Abstract
In this review, we have summarized the existing knowledge of ulcerative colitis (UC) markers based on current literature, specifically, the roles of potential new biomarkers, such as circulating, fecal, genetic, and epigenetic alterations, in UC onset, disease activity, and in therapy response. UC is a complex multifactorial inflammatory disease. There are many invasive and non-invasive diagnostic methods in UC, including several laboratory markers which are employed in diagnosis and disease assessment; however, colonoscopy remains the most widely used method. Common laboratory abnormalities currently used in the clinical practice include inflammation-induced alterations, serum autoantibodies, and antibodies against bacterial antigens. Other new serum and fecal biomarkers are supportive in diagnosis and monitoring disease activity and therapy response; and potential salivary markers are currently being evaluated as well. Several UC-related genetic and epigenetic alterations are implied in its pathogenesis and therapeutic response. Moreover, the use of artificial intelligence in the integration of laboratory biomarkers and big data could potentially be useful in clinical translation and precision medicine in UC management.

Abstract
Hereditary cancer syndromes predispose to several types of cancer due to inherited pathogenic variants in susceptibility genes. We describe the case of a 57-year-old woman, diagnosed with breast cancer, and her family. The proband belongs to a family with a suspected tumor syndrome, due to other cancer cases in her family from the paternal and maternal sides. After oncogenetic counseling, she was subjected to mutational analysis with an NGS panel analyzing 27 genes. The genetic analysis showed two monoallelic mutations in low penetrance genes, c.1187G>A (p.G396D) in MUTYH and c.55dup (p.Tyr19Leufs*2) in BRIP1. One of the mutations was inherited from the maternal side and the other from the paternal side, suggesting two different cancer syndrome types in the family. MUTYH mutation was related to the onset of cancers on the paternal side, as confirmed by the occurrence of the same mutation in the proband's cousin. BRIP1 mutation was found in the proband's mother, indicating that it was related to the cancer cases observed on the maternal side, including breast cancer and sarcoma. Advances in NGS technologies have allowed the identification of mutations in families with hereditary cancers in genes other than those related to a specific suspected syndrome. A complete oncogenetic counseling, together with molecular tests that enable a simultaneous analysis of multiple genes, is essential for the identification of a correct tumor syndrome and for clinical decision-making in a patient and his/her family. The detection of mutations in multiple susceptibility genes allows the initiation of early risk-reducing measures for identified mutation carriers among family members and to include them in a proper surveillance program for specific syndromes. Moreover, it may enable an adapted treatment for the affected patient, permitting personalized therapeutic options.

Abstract
In the present study, immunogenicity data in 61 vaccinated healthcare workers (HCWs) either infection naïve (naïve HCWs) or with infection of Delta and/or Omicron COVID-19 (experienced HCWs) were evaluated up to 270 days after the second dose of BNT162b2 vaccine and up to 90 days after a booster dose. A decrease in antibody levels at 270 days following administration of the second dose (p = 0.0335) was observed, although values did not fall below the positivity threshold (33.8 BAU/ml). After booster vaccination, antibody levels increased after 30 days (p = 0.0486), with much higher values than after first and second vaccination. Antibody levels then decreased at 60 and 90 days after the booster dose. A comparison between mean antibody levels of naïve and experienced HCWs revealed higher values in experienced HCWs, resulting from both natural and vaccination-induced immunity. A total of 14.7% of HCWs contracted the Omicron virus variant after the vaccine booster, although none showed severe symptoms. These results support that a booster dose results in a marked increase in antibody response that subsequently decreases over time.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is the seventh leading cause of cancer death worldwide; most of cases are sporadic, however about 5% to 10% report a hereditary predisposition. Several hereditary syndromes have been associated with familial pancreatic cancer (FPC) onset, including hereditary breast and ovarian cancer syndrome (HBOC), Lynch syndrome (LS), Familial atypical multiple mole melanoma (FAMMM), Familial adenomatous polyposis (FAP), Li-Fraumeni syndrome (LFS), Peutz-Jeghers syndrome (PJS), and Hereditary pancreatitis (HP).The aim of this study was to determine the mutational status of a cohort of 56 HBOC families, 7 LS families, 3 FAP and FAMMM families, and 1 LFS family with at least one case of PDAC. Mutation analysis of BRCA1/2, ATM, CHEK2, PALB2, RAD51C, RAD51D, NBN, CDH1, TP53, MLH1, MSH2, MSH6, and PMS2 genes, showedmutation in BRCA1/2, MLH1, and APC genes. We founda high mutation rate in patients belong HBOC and LS families, with a percentage of 28.6% in both syndromes and prevalence in HBOC of BRCA2 mutations with one case of double mutation in BRCA2 gene. In FAP family, we found a pathogenic mutation in APC gene in 1/3 families. We observed an early onset of PDAC and a lower survival in PDAC patients belonging to mutated families, while no evidence of possible pancreatic cancer cluster regions was found. Moreover, we identified a novel BRCA2 germline mutation, c.5511delT (p.Phe1837LeufsX3), not reported in any database, that segregated with disease in HBOC patients. Mutational analysis was extended to family membersof mutated patients, both healthy and cancer affected, which revealed 23 unaffected family members that inherited the proband's mutation. Although correlative by its nature, the presence of a BRCA mutation in PDAC patients may have benefits in terms of optimized treatment and longer outcome.

Abstract
It is well-known that the Coronavirus Disease 2019, which is caused by the beta-coronavirus severe acute respiratory syndrome (SARS-CoV-2), emerged in December 2019 followed by an outbreak first reported in Wuhan, China. Thus far, vaccination appears to be the only way to bring the pandemic to an end. In the present study, immunogenicity data was evaluated using LIAISON® SARS-CoV-2 TrimericS IgG assay (DiaSorin S.p.A) among a sample of 52 vaccinated healthcare workers, five of whom were previously infected with SARS-CoV-2 and 47 who were seronegative, over a time span of ≤90 days following the second dose of the BNT162b2 mRNA vaccine. The test detects antibodies against the Trimeric complex (S1, S2 and receptor binding domain). The overall mean value of the serum levels of IgG antibodies to SARS-CoV-2 30 days following the second dose of the vaccine was 1,901.8 binding arbitrary unit (BAU)/ml, after 60 days the mean value declined to 1,244.9 BAU/ml. The antibody levels then reached a plateau, as confirmed by the antibody test carried out 90 days following the second dose, which revealed a mean value of 1,032.4 BAU/ml (P<0.0001). A higher level was observed at all three times in male subjects compared with female subjects, and in younger male participants compared with female participants, although these differences did not reach a statistically significant level. Similarly, no significant difference was found in antibody values at different times according to age. After the second dose of the vaccine, two subjects were infected with SARS-CoV-2, and an increase in antibody values in the third assay was observed in both individuals.

Abstract
Over the centuries, humans have traditionally used garlic (Allium sativum L.) as a food ingredient (spice) and remedy for many diseases. To confirm this, many extensive studies recognized the therapeutic effects of garlic bulbs. More recently, black garlic (BG), made by heat-ageing white garlic bulbs, has increased its popularity in cuisine and traditional medicine around the world, but there is still limited information on its composition and potential beneficial effects. In this study, the metabolite profile of methanol extract of BG (BGE) was determined by high-performance liquid chromatography coupled to tandem mass spectrometry in high-resolution mode. Results allowed to establish that BGE major components were sulfur derivatives, saccharides, peptides, organic acids, a phenylpropanoid derivative, saponins, and compounds typical of glycerophospholipid metabolism. Characterization of the BGE action in cancer cells revealed that antioxidant, metabolic, and hepatoprotective effects occur upon treatment as well as induction of maturation of acute myeloid leukemia cells. These results are interesting from the impact point of view of BG consumption as a functional food for potential prevention of metabolic and tumor diseases.

Abstract
BACKGROUND This study was carried out to estimate the seroprevalence of SARS-CoV-2 antibodies in a Southern Italian population. METHODS The study was performed among students and workers of the University of Campania "Luigi Vanvitelli" and the relative Teaching Hospital. Participants were invited to undergo a blood sampling, an interview or to complete a self-administered questionnaire. RESULTS A total of 140 participants (5.8%) tested positive for SARS-CoV-2 antibodies. Positive SARS-CoV-2 test results increased significantly during the months of testing, and those who had had at least one symptom among fever, cough, dyspnea, loss of taste or smell and who had had contact with a family member/cohabitant with confirmed COVID-19 were more likely to test positive. Faculty members were less likely to have a positive test result compared to the healthcare workers (HCWs). Among HCWs, physicians showed the lowest rate of seroconversion (5.2%) compared to nurses (8.9%) and other categories (10%). Nurses and other HCWs compared to the physicians, those who had had at least one symptom among fever, cough, dyspnea, loss of taste or smell, and who had had contact with a family member/cohabitant with confirmed COVID-19 were more likely to test positive. CONCLUSIONS The results have demonstrated that SARS-CoV-2 infection is rapidly spreading even in Southern Italy and confirm the substantial role of seroprevalence studies for the assessment of SARS-CoV-2 infection circulation and potential for further spreading.

Abstract
Prostate cancer (PCa) is globally the second most diagnosed cancer type and the most common cause of cancer-related deaths in men. Family history of PCa, hereditary breast and ovarian cancer (HBOC) and Lynch syndromes (LS), are among the most important risk factors compared to age, race, ethnicity and environmental factors for PCa development. Hereditary prostate cancer (HPCa) has the highest heritability of any major cancer in men. The proportion of PCa attributable to hereditary factors has been estimated in the range of 5–15%. To date, the genes more consistently associated to HPCa susceptibility include mismatch repair (MMR) genes (MLH1, MSH2, MSH6, and PMS2) and homologous recombination genes (BRCA1/2, ATM, PALB2, CHEK2). Additional genes are also recommended to be integrated into specific research, including HOXB13, BRP1 and NSB1. Importantly, BRCA1/BRCA2 and ATM mutated patients potentially benefit from Poly (ADP-ribose) polymerase PARP inhibitors, through a mechanism of synthetic lethality, causing selective tumor cell cytotoxicity in cell lines. Moreover, the detection of germline alterations in MMR genes has therapeutic implications, as it may help to predict immunotherapy benefits. Here, we discuss the current knowledge of the genetic basis for inherited predisposition to PCa, the potential target therapy, and the role of active surveillance as a management strategy for patients with low-risk PCa. Finally, the current PCa guideline recommendations are reviewed.

Abstract
Endometrial cancer (EC) is the fifth most common cancer in women from developed countries, accounting for 4.8% of new cases and 2.1% of deaths. The genetic basis for the familial risk of endometrial cancer has not been completely defined. Mostly, hereditary EC is part of two syndromes as Lynch syndrome (LS) and Hereditary Breast and Ovarian Cancer syndrome (HBOC). LS is the prototypical hereditary cancer syndrome in EC and accounts for 2-6% of all endometrial cancers. This disease is caused by autosomal dominant mutations in DNA mismatch repair (MMR) genes. Patients carrying a germline mutation in one of the MMR genes have a cumulative lifetime risk to develop EC of 20-70%. HBOC is an autosomal dominantly inherited disease, which mostly predisposes to breast and ovarian cancers, but it can be also associated with other malignancies. HBOC results from germline mutations in BRCA1/2 genes. The aim of this study was to determine the mutational status of a cohort of 40 EC patients, 19 belonging to families with LS and 21 to HBOC. Mutation analysis of MLH1, MSH2, BRCA1 and BRCA2 genes showed pathogenic variants in 17/40 (42.5%) patients. Out of 19 patients belonging to LS families, 8 (42.1%) showed a pathogenic variant. Out of 21 patients belonging to HBOC families, 9 (42.8%) showed a pathogenic variant. 1/21 (4.8%) patient report 1 variant of unknown significance (UV), c.599 C > T (p.T200I), in BRCA2. Moreover, in 1/21 (4.8%) patient we identified a novel missense variant in BRCA2, c.9541A > T (p.Met3181Leu). Mutational analysis was extended to family members, both healthy and cancer affected, of mutated patients; all the tested relatives affected with cancer displayed the pathogenic variant. Our data suggest that patients with hereditary EC have a high percentage of mutations in the LS and HBOC main susceptibility genes; therefore, the surveillance for EC, already indicated in LS patients, should also be recommended for patients with HBOC.

Abstract
Familial adenomatous polyposis (FAP) is a rare genetic disorder caused mainly by monoallelic mutations of APC gene. The hereditary breast and ovarian cancer (HBOC) syndrome is an autosomal dominantly inherited disease, which mostly predisposes to breast and ovarian cancers as a result of germline mutations in BRCA1 or BRCA2 genes. In a family, mutations in two cancer susceptibility genes are extremely rare. We studied a family with a case of a 46 years-old woman affected with FAP and ovarian cancer. The patient was affected with profuse FAP since the age of 18 years and a serous ovarian cancer was diagnosed at the age of 45 years. She reported other FAP cases and one case of breast cancer in maternal family. Initially, she was tested for FAP predisposition with mutational analysis of APC gene that revealed the presence of a frameshift mutation, c.3927_3931delAAAGA (p.Glu1309AspfsX4). The presence of ovarian cancer in the patient and of a breast cancer case in the maternal family, suggested an extended analysis to HBOC susceptibility genes that led to the detection of a frameshift mutation, c.3756_3759delGTCT (p.Ser1253Argfs), in BRCA1 gene. The genetic analysis was extended also to family members. The occurrence of the double mutation in APC and BRCA1 genes in the patient was responsible for the onset of FAP and ovarian cancer respectively. The genetic counselling in hereditary cancer with a careful analysis of the pedigree allows identifying the gene to be analyzed. The development of multi-gene panels testing for cancer predisposition, with next generation sequencing (NGS), may reveal mutations in genes of high and moderate penetrance for cancer, although at a low frequency and allows diagnosing a possible double heterozygosity. This enables an adjusted treatment for the affected patient and is critical as it allows initiation of early risk-reducing measures for identified mutation carriers among family members.

Abstract
INTRODUCTION Male Breast Cancer (MBC) is a rare disease, about 1% of all breast cancers worldwide and less than 1% of cancers occurring in men. The bilateral male breast cancer (bMBC) is extremely rare. Germline mutations of BRCA1/BRCA2 genes are associated with a significantly increased risk of cancer in MBC; the role of PALB2 remains to be clarified. Our main goal was to provide contribution on characterization of BRCA1/BRCA2 and PALB2 mutations in MBC patients. METHODS We observed 28 MBC cases; one of them was a bMBC. Screening for BRCA1, BRCA2 and PALB2 genes was performed on all 28 MBC patients. Mutational analysis was extended to family members of mutated patients. RESULTS In our study, the MBC incidence was 5.2% and for bMBC was 3.6%. Mutation analysis showed pathogenic mutations in 11/28 (39.3%) patients; 2/28 (7.1%) displayed a mutation in BRCA1, 8/28 (28.6%) in BRCA2 and 1/28 (3.6%) in PALB2. Out of 11 mutated patients, one (9.1%) reported a double mutation in BRCA2. Personal history of other cancers was reported in 2/28 (7.1%) patients affected by bladder cancer. A first/second degree family history of breast/ovarian and other cancers occurred in 23/28 (82.1%) patients. CONCLUSION Our findings indicate BRCA2 as the main MBC susceptibility gene and describe an increased risk of bMBC and bladder cancer in mutated patients. The identification of mutations in MBC susceptibility genes supports the usage of oncology prevention programs in affected patients and their relatives carrying the mutation.

Abstract
Aims and background E-cadherin, also known as uvomorulin or cell-CAM 120/80, is one of the subclasses of cadherins, CA2+-dependent cell adhesion molecules. Several recent studies have suggested that loss of E-cadherin may be associated with tumor progression, such as in lung, gastric, hepatocellular, breast and prostatic carcinoma. Assessment of E-cadherin serum levels in lung cancer showed a relation to histologic type. Methods and study design Using an enzyme immunoassay, we determined E-cadherin serum levels in 79 patients affected with lung cancer (stage l–IV), 9 patients with breast cancer, 23 patients with different benign diseases, and 20 healthy patients. Results At a specificity level of 90%, E-cadherin diagnostic sensitivity was 66.6%, 47.6% and 43.7% in patients affected with squamous cell carcinoma, small cell carcinoma and adenocarcinoma, respectively. Conclusions Preliminary results suggest the use of serum E-cadherin as a prospective tumor marker.

Abstract
An immunoradiometric method of the second generation (IRMA II) is widely used to determine CA125 serum levels. In this study we have evaluated the performance characteristics of a commercially available IRMA CA125 II (Byk-Gulden, Sangtec Diagnostics). The CA125 serum levels were determined in several groups of patients (healthy women, pregnant women, subjects affected by benign and malignant ovarian cancer, patients with liver diseases) with two IRMAs CA125 II (Byk-Gulden, Sangtec Diagnostica and Centocor, Diagnostic Division) and IRMA CA125 I (Byk-Gulden, Sangtec Diagnostica). Our results show a good analytic performance of IRMA CA125 II (Byk-Gulden, Sangtec Diagnostica), a good correlation between IRMAs CA125 II (Byk-Gulden, Sangtec Diagnostica and Centocor, Diagnostic Division), but an unacceptable correlation between IRMAs CA125 II (Byk-Gulden, Sangtec Diagnostica and Centocor, Diagnostic Division) and IRMA CA125 I. A statistically significant difference was observed comparing the values obtained with both IRMAs CA125 II and IRMA CA125 I in the groups of patients. In contrast no statistically significant difference was observed when we compared the values obtained with IRMA CA125 II (Byk-Gulden, Sangtec Diagnostica) and IRMA CA125 II (Centocor, Diagnostic Division). CA125 serum values obtained with the second-generation kits were different from those obtained with the first-generation one; consequently, it is important, especially in the follow-up of cancer patients, that CA125 serum values be obtained with kits of the same generation. Our data seem to suggest the use of second-generation kits to determine CA125 serum levels.

Abstract
PALB2 gene is mutated in about 1-2% of familial breast cancer as well as in 3-4% of familial pancreatic cancer cases. Few studies have reported mutations in Italian patients with breast or pancreatic cancer. We evaluate the occurrence of PALB2 mutations in Italian patients affected with hereditary breast and ovarian cancers and define the pathological significance of the putative allelic variants. We recruited 98 patients (F = 93, M = 5) affected with breast and/or ovarian cancer, negative for mutations in BRCA1 and BRCA2 (BRCAX). Genomic DNA was isolated from peripheral blood lymphocytes, PALB2 coding regions and adjacent intronic were sequenced; in silico predictions were carried out using prediction programs. Mutational analysis of PALB2 gene revealed the novel mutation c.1919C>A (p.S640X) in a 29 years old woman with breast cancer. The c.1919C>A (p.S640X) mutation causes the lack of C-terminus region inducing alteration of MORF4L1-PALB2 association and the lack of interaction of PALB2 with RAD51 and BRCA2. In addition, we identified two novel PALB2 variants, c.3047T>C (p.F1016S) and c.*146A>G. In silico analysis conducted for c.*146A>G indicates that this variant does not affect the splicing while c.3047T>C (p.F1016S) was predicted as damaging in three classifier algorithms. The proband carrier of c.3047T>C (p.F1016S) showed two breast cancer cases, two ovarian cancer cases and one pancreatic cancer in mother's family. c.3047T>C (p.F1016S) and c.*146A>G should be considered PALB2 UVs even though the genotype-phenotype correlation for these variants remains still unclear. Our findings indicate that the presence of PALB2 mutation should be routinely investigated in hereditary breast and ovarian cancers families since it could be of clinical relevance for clinical management.

Abstract
Lichens are valuable natural resources used for centuries throughout the world as medicine, food, fodder, perfume, spices and dyes, as well as for other miscellaneous purposes. This study investigates the antiproliferative, antibacterial and antifungal activity of the acetone extract of the lichen Xanthoria parietina (Linnaeus) Theodor Fries and its major secondary metabolite, parietin. The extract and parietin were tested for antimicrobial activity against nine American Type Culture Collection standard and clinically isolated bacterial strains, and three fungal strains. Both showed strong antibacterial activity against all bacterial strains and matched clinical isolates, particularly against Staphylococcus aureus from standard and clinical sources. Among the fungi tested, Rhizoctonia solani was the most sensitive. The antiproliferative effects of the extract and parietin were also investigated in human breast cancer cells. The extract inhibited proliferation and induced apoptosis, both effects being accompanied by modulation of expression of cell cycle regulating genes such as p16, p27, cyclin D1 and cyclin A. It also mediated apoptosis by activating extrinsic and intrinsic cell death pathways, modulating Tumor Necrosis Factor-related apoptosis-inducing ligand (TRAIL) and B-cell lymphoma 2 (Bcl-2), and inducing Bcl-2-associated agonist of cell death (BAD) phosphorylation. Our results indicate that Xanthoria parietina is a major potential source of antimicrobial and anticancer substances.

Abstract
Male breast cancer (MBC) is a rare disease, accounting for ~1% of all breast cancer cases worldwide. Although other genes are also involved, predisposing genetic factors to MBC include germline mutations in the BRCA genes (BRCA2). Among the other genes, partner and localizer of BRCA2 (PALB2) is considered a moderate-penetrance breast cancer susceptibility gene that may also play a role in MBC predisposition. Thus, the aim of the present study was to determine the PALB2 gene status in 8 MBC cases selected from a cohort of 181 hereditary breast and/or ovarian cancer probands. We performed PALB2 mutational analysis by direct sequencing of 13 exons and adjacent intronic regions. This study showed the presence of a PALB2 truncating mutation in 1/8 (12.5%) cases. This novel mutation was named c.1285_1286delAinsTC (p.I429SfsX12) and is localized in exon 4 of PALB2, in the region encoding for the ChAM motif which is important for the efficient association of PALB2 to chromatin and for recruitment of the BRCA complex to accumulate RAD51 at double-strand break sites. Our findings indicate that PALB2 could be added to the list of breast cancer susceptibility genes also in families with MBC cases.

Abstract
AIM Arg72Pro is a polymorphism commonly occurring in the proline-rich domain of Tp53. It can determine the development of different types of cancers, such as breast, lung, cervical, colorectal and hepatocellular carcinoma. Previous studies reported a correlation between Pro72 homozygosity and the clinical course of ulcerative colitis (UC). Our aim was to evaluate Arg72Pro genotype in patients who underwent proctocolectomy with ileo-pouch-anal anastomosis (IPAA) for UC compared with those who did not need surgery. MATERIAL OF STUDY The distribution of the different genotype of Arg72Pro was studied in 264 (234 medically treated [MT] and 30 IPAA) patients affected with UC observed between 2008 and 2011. IPAA patients underwent restorative proctocolectomy for refractory UC; MT ones were managed medically. Blood samples for genotyping were collected from all patients. Arg72Pro genotype analysis was carried out by polymerase chain reaction confronting two-pair primers (PCR-CTPP). RESULTS In MT patients (n=234) Arg/Arg, Arg/Pro and Pro/Pro frequencies were 51.28%, 41.02% and 7.7%, respectively, while in IPAA patients (n=30) were 53.4%, 23.3% and 23.3%, respectively. A statistically significant association was found between Pro/Pro and need for surgery (p=<0.0059, χ =7.59). CONCLUSION Our results showed that the Pro/Pro genotype was higher in IPAA (23.3%) than in MT (7.7%) patients. In UC patients the proline homozygosity identifies likeliness to resist to any standard pharmacologic therapy. It could potentially identify patients who would benefit from early surgical treatment, thereby reducing the rate of emergency colectomies and complications related to them. KEY WORDS Arg72Pro, Arg72Pro polymorphism, Ileopouch-anal anastomosis, IPAA, p53 polymorphism, Ulcerative colitis.

Abstract
BACKGROUND An estimated 5 % – 10 % of all breast cancers are due to an inherited predisposition and, out of these, about 30 % are caused by germline mutations of the BRCA1 and BRCA2 genes. The prevalence of germline mutations in theBRCA1 and BRCA2 genes varies among ethnic groups. The aims of this study are to evaluate deleterious mutations and genomic rearrangements in BRCA1/2 genes and the CHEK21100delC mutation in a cohort of Italian women affected with hereditary breast and/or ovarian cancer. In addition we clarify the effect of the novel variants identified in BRCA2 gene bymRNA analysis and prediction software. METHODS We enrolled 103 consecutive Italian patients affected with hereditary breast and/or ovarian cancer, aged23 – 69 years. RESULTS We found BRCA1/2 mutations in 15/103 probands(14.6 % ). Among these, a BRCA2 gene mutation has not been described previously. In addition, we identified five novel BRCA2 variants (S1341, IVS1-59t > c, IVS11-74insA, IVS12 + 74c > g and I1167V). No genomic BRCA1/2re arrangements or CHEK2 1100delC mutation was found in our patients. The novel BRCA2 mutation NS1742del(p.N1742_S1743del) was an in-frame 6 bp deletion that results in loss of two amino acids. CONCLUSIONS In silico analysis conducted for S1341, IVS1-59t > c, IVS11-74insA and IVS12 + 74c > g of BRCA2 predicted the variants as neutral and benign, whereas the results for I1167V was inconclusive. mRNA analysis for the novel BRCA2 intronic variant IVS11-74insA and the already published BRCA1 variant C197 shows that they have no effect on the splicing. These results are in agreement with in silico analysis.

Abstract
Peripheral arterial disease (PAD) is a chronic condition caused by atherosclerosis and is a severe complication of type 2 diabetes (T2D). We hypothesised that chronic condition of arterial disease engenders inflammation and endothelial damage in response to circulating cytokines released in the blood stream of PAD patients. We explored the levels of circulating cytokines in PAD patients with and without diabetes by multiplex cytokine array compared with non-PAD controls. Serum from PAD patients with or without diabetes showed high levels of VEGF, IFN-gamma, TNF-alpha, MCP-1, and EGF. VEGF levels correlated with TNF-alpha and IFN-gamma, significantly. Endothelial cells (ECs) were exposed to the different altered cytokines to evaluate changes in cell growth, migration and tubule-like formation, displaying impairment on proliferation, migration and tubule formation. Our findings demonstrate that a set of cytokines is significantly increased in the serum of PAD patients. These cytokines act to induce endothelial dysfunction synergistically. VEGF strongly correlated with TNF-alpha and IFN-gamma, opening new therapeutic perspectives.

Abstract
OBJECTIVES Curative properties of medicinal plants such as Psidium guajava L. (Myrtaceae) have often been indicated by epidemiological studies on populations in which these fruits are consumed daily. However, complete characterization of the active principles responsible for this ability has never been performed. Here, we have characterized P. guajava's anti-cancer potential and identified the parts of the fruit involved in its anti-neoplastic action. MATERIALS AND METHODS We studied morphology of our cells, cell cycle characteristics and apoptosis and performed immunostaining, differentiation and western blot analyses. RESULTS We report that the P. guajava extract exerted anti-cancer control on both haematological and solid neoplasias. P. guajava extract's anti-tumour properties were found to be tightly bound to induction of apoptosis and differentiation. Use of ex vivo myeloid leukaemia blasts corroborated that P. guajava was able to induce cell death but did not exhibit anti-cancer effects on all malignant cells investigated, indicating selective activity against certain types of tumour. Analyses of P. guajava pulp, peel and seeds identified the pulp as being the most relevant component for causing cell cycle arrest and apoptosis, whereas peel was responsible for causing cell differentiation. P. guajava itself and its pulp-derived extract were found to induce apoptosis accompanied by caspase activation and p16, p21, Fas ligand (FASL TNF super-family, member 6), Bcl-2-associated agonist of cell death (BAD) and tumour necrosis factor receptor super-family, member 10b (DR5), overexpression. CONCLUSIONS Our findings showed that P. guajava L. extract was able to exert anti-cancer activity on cultures in vitro and ex vivo, supporting the hypothesis of its anti malignant pro-apoptotic modulation.

Abstract
Critical limb ischemia (CLI) is the end stage of peripheral vascular disease (PVD). One third of CLI patients progresses to leg amputation with high associated morbidity and mortality. In no-option patients with end-stage critical limb ischemia, bone marrow cell transplantation has shown promising results, improving leg perfusion to the level of reducing major amputations and allowing limb salvage. We recently reported the successful application of an innovative protocol based on repeated autologous bone marrow cell transplantation, which resulted in an effective and feasible strategy for achieving long-term revascularization in patients with severe CLI. In an effort to understand the clinical benefit provided by stem cells therapy in patients with CLI, we characterized the marrow-derived stromal cells of CLI patients and we provided a correlation between the in vitro features of these cells and the clinical follow up at 12 months. We showed that cells derived from CLI patients had a reduced capacity to proliferate, adhere, and migrate, but that they stimulated proliferation and migration of endothelial cells through the release of VEGF-A, supporting the idea that the paracrine mechanisms underpinned the biological effects of long-term angiogenesis in CLI patients.

Abstract
INTRODUCTION hMLH1 gene, lying on chromosome 3p21-23, is a key factor of the mismatch repair (MMR) complex, which amends DNA replication errors. MMR alterations are involved in the development of both hereditary and sporadic forms of colorectal carcinoma related to ulcerative colitis (UC). I219V Polymorphism is located on exon 8 of hMLH1 and provides an aminoacidic substitution of isoleucine to valine, on the protein codon 219. This may affect the speed and fidelity of protein synthesis because of a tRNA paucity or changes in the mRNA secondary structure. Most of the hereditary nonpolyposis colon cancer-associated missense mutations of hMLH1 cause structural changes of the amino- or carboxy-terminal regions, involving the domains that interact with ATP and hPMS2. AIMS AND METHODS In this study, we analyzed the hMLH1 I219V polymorphism frequency in colectomized patients with UC. Venous blood from 100 ulcerative patients and 97 apparently healthy subjects has been collected. Out of 100 patients affected with UC, 75 noncolectomized showed an alternating course of disease, while 25 did not respond to the common drugs, and underwent colectomy. Genotyping was performed by polymerase chain reaction and following enzymatic digestion by BccI. RESULTS No significant differences were found between patients with UC and controls both for genotype and allele frequencies. However, our data show a significant association when colectomized and noncolectomized patients are compared. The frequencies of G homozygosity were 28% in colectomized and 10.7% in noncolectomized patients (p < 0.05, chi(2) = 4.4, Odds ratio = 3.3). The allele frequencies of allele A were 52% in colectomized and 68% in noncolectomized patients; while those of allele G were 48% and 32%, respectively. CONCLUSIONS I219V polymorphism in hMLH1 could influence the clinical course of the disease and lead to resistance to therapy.

Abstract
Background: BPA (bisphenol A or 2,2-bis(4-hydroxy-phenol)propane) is present in the manufacture of polycarbonate plastic and epoxy resins, which can be used in impact-resistant safety equipment and baby bottles, as protective coatings inside metal food containers, and as composites and sealants in dentistry. Recently, attention has focused on the estrogen-like and carcinogenic adverse effects of BPA. Thus, it is necessary to investigate the cytotoxicity and apoptosis-inducing activity of this compound. Methods: Cell cycle, apoptosis and differentiation analyses; western blots. Results: BPA is able to induce cell cycle arrest and apoptosis in three different acute myeloid leukemias. Although some granulocytic differentiation concomitantly occurred in NB4 cells upon BPA treatment, the major action was the induction of apoptosis. BPA mediated apoptosis was caspase dependent and occurred by activation of extrinsic and intrinsic cell death pathways modulating both FAS and TRAIL and by inducing BAD phosphorylation in NB4 cells. Finally, also non genomic actions such as the early decrease of both ERK and AKT phosphorylation were induced by BPA thus indicating that a complex intersection of regulations occur for the apoptotic action of BPA. Conclusion: BPA is able to induce apoptosis in leukemia cells via caspase activation and involvement of both intrinsic and extrinsic pathways of apoptosis.

Abstract
OBJECTIVE To investigate whether CYP17 T>C polymorphism and polymorphisms C1558T and Val80 of CYP19 are related to endometriosis. DESIGN Clinical study. PATIENT(S) Women affected with endometriosis (n = 104) and control group (n = 86). The diagnosis of endometriosis was confirmed by the histologic examination of the endometriotic lesions. RESULT(S) In patients affected with endometriosis, we observed that AA and CC genotypes were significantly represented in Val80 and C1558T polymorphisms of CYP19. CONCLUSION(S) The molecular mechanisms that underlie the development of endometriosis are unclear. Both environmental and genetic factors are involved in the pathogenesis of the disease. The inheritable susceptibility to endometriosis justifies the growing interest in identifying genes and/or genetic polymorphisms that predispose women to an increased risk of developing endometriosis. The identification of single-nucleotide polymorphism (SNP), probably linked to endometriosis, could help to explain its pathogenesis.

Abstract
BACKGROUND The p53 tumor suppressor protein plays a fundamental role in maintaining genomic integrity through its ability to arrest the cell cycle in G1 and induce apoptosis. The proapoptotic activity of p53 seems to be strictly related to proline-rich regions, homologous to the SH3 binding domain. In the literature, reported data suggest a role for polymorphism at codon 72 of p53 in the predisposition to neoplastic transformation, although the results are still controversial. In this study, we investigated Arg72Pro polymorphism of p53 and related this polymorphism to clinical parameters in patients affected with ulcerative colitis (UC). METHODS We studied 243 consecutive outpatients affected with well-established UC. The control group comprised 142 healthy blood donors, with age and sex comparable to those of the patients. RESULTS p53 Pro/Pro was significantly related to the clinical course and duration of disease (odds ratio, 55.8 and 8.8, respectively). Nineteen of 24 patients with Pro homozygosity had a duration of disease >7 years. In contrast, 87 of 123 patients with Arg/Arg had short-standing UC (< or =7 yrs) and 66 of 96 with Arg/Pro had short-standing UC (chi-squared, 22.86; P < 0.0001). Thirty-four of 243 patients affected with UC had a positive family history for colorectal carcinoma (CRC). In those patients p53, Pro/Pro was significantly related to a family history of CRC (odds ratio, 38.1). CONCLUSIONS These preliminary data suggest that polymorphism at codon 72 of the p53 gene influences the clinical course of UC, with continuous disease associated with p53 Pro homozygosity.

Abstract
Curative properties of some medicinal plants such as the Feijoa sellowiana Bert. (Myrtaceae), have been often claimed, although the corresponding molecular mechanism(s) remain elusive. We report here that the Feijoa acetonic extract exerts anti-cancer activities on solid and hematological cancer cells. Feijoa extract did not show toxic effects on normal myeloid progenitors thus displaying a tumor-selective activity. In the Feijoa acetonic extract, fractionation and subsequent purification and analyses identified Flavone as the active component. Flavone induces apoptosis which is accompanied by caspase activation and p16, p21 and TRAIL over-expression in human myeloid leukemia cells. Use of ex vivo myeloid leukemia patients blasts confirms that both the full acetonic Feijoa extract and its derived Flavone are able to induce apoptosis. In both cell lines and myeloid leukemia patients blasts the apoptotic activity of Feijoa extract and Flavone is accompanied by increase of histone and non-histone acetylation levels and by HDAC inhibition. Our findings show for the first time that the Feijoa apoptotic active principle is the Flavone and that this activity correlates with the induction of HDAC inhibition, supporting the hypothesis of its epigenetic pro-apoptotic regulation in cancer systems.

Abstract
BACKGROUND The recent introduction of new automated assays needs careful definition of reference values in healthy children. The aim of this study was to determine serum parathyroid hormone (PTH) and osteocalcin in a large group of healthy children according to age. METHODS We selected 2,288 healthy children (1,079 girls, 1,209 boys), aged 2-16 years. Serum PTH and osteocalcin were assayed with a two-site immunochemiluminometric assay adapted on an automated analyzer, the Liaison. RESULTS Significant differences were found between the mean serum values of PTH and osteocalcin in boys and girls in all age groups (p <0.001). Boys' and girls' PTH values ranged from 3.42-22.30 ng/l and 2.31-24.49 ng/l, respectively; serum osteocalcin ranged from 3.85-17.80 nmol/l in boys and 3.74-17.38 nmol/l in girls. CONCLUSIONS The results of this study contribute to the establishment of reference values in healthy children for PTH and osteocalcin assays.

Abstract
Antiestrogens used for breast cancer (BC) treatment differ among each other for the ability to affect estrogen receptor (ER) activity and thereby inhibit hormone-responsive cell functions and viability. We used high-density cDNA microarrays for a comprehensive definition of the gene pathways affected by 17beta-estradiol (E2), ICI 182,780 (ICI), 4OH-tamoxifen (Tamoxifen), and raloxifene (RAL) in ER-positive ZR-75.1 cells, a suitable model to investigate estrogen and antiestrogen actions in hormone-responsive BC. The expression of 601 genes was significantly affected by E2 in these cells; in silico analysis reveals that 86 among them include one or more potential ER binding site within or near the promoter and that the binding site signatures for E2F-1, NF-Y, and NRF-1 transcription factors are significantly enriched in the promoters of genes induced by estrogen treatment, while those for CAC-binding protein and LF-A1 in those repressed by the hormone, pointing to novel transcriptional effectors of secondary responses to estrogen in BC cells. Interestingly, expression of 176 E2-regulated mRNAs was unaffected by any of the antiestrogens tested, despite the fact that under the same conditions the transcriptional and cell cycle stimulatory activities of ER were inhibited. On the other hand, of 373 antiestrogen-responsive genes identified here, 52 were unresponsive to estrogen and 25% responded specifically to only one of the compounds tested, revealing non-overlapping and clearly distinguishable effects of the different antiestrogens in BC cells. As some of these differences reflect specificities of the mechanism of action of the antiestrogens tested, we propose to exploit this gene set for characterization of novel hormonal antagonists and selective estrogen receptor modulators (SERMs) and as a tool for testing new associations of antiestrogens, more effective against BC.

Abstract
AIM To evaluate serum osteoprotegerin (OPG) concentrations in relation to age-dependent changes in serum markers of bone metabolism and systemic inflammation. METHODS Two-hundred and eighty-three healthy subjects were evaluated for plasma estimated creatinine clearance (Cr-clearance), C-reactive protein (CRP), bone alkaline phosphatase, C-telopeptides of type-1 collagen (CrossLaps), nuclear factor-kappaB ligand (RANKL) and OPG concentrations. RESULTS In adult subjects (82 cases aged between 27 and 64 years) serum OPG concentrations were significantly and independently correlated with RANKL and Cr-clearance (R(2): 0.29), but not with CRP and biochemical markers of bone metabolism. In old subjects who were between 65 and 84 years of age (52 cases) serum OPG concentrations were significantly higher as compared with the adult subjects and correlated independently and significantly with serum RANKL, Cr-clearance and CrossLaps values (R(2): 0.63). The highest OPG values were found in the long-lived subjects (149 cases with ages between 85 and 110 years) who also showed increased serum CrossLaps and CRP concentrations as compared with the younger subjects. However, in the long-lived subjects serum OPG concentrations were significantly and independently correlated with Cr-clearance and CRP (R(2): 0.45) but not with CrossLaps values. CONCLUSIONS These data would suggest that different factors might be responsible for the age-dependent enhancement of OPG production. Bone metabolism would seem to be the most important factor influencing serum OPG concentrations in old subjects under 85 years of age, whereas in long-lived subjects the circulating values of this cytokine seem to be mainly correlated with serum CRP which could be a marker of inflammation and cardiovascular risk.

Abstract
OBJECTIVE In this prospective study, we investigated whether the development of interferon (IFN)-alpha-related autoimmune thyroiditis (IFN-AT) was correlated with the sequential changes of cytokine pattern induced by IFNalpha in the peripheral lymphocytes. PATIENTS AND METHODS We enrolled 18 hepatitis C virus (HCV)-positive patients who developed IFN-AT, eight patients with euthyroidism [IFN-AT(Eu)] and 10 with thyroid dysfunction [IFN-AT(Dy)]. Twenty HCV-positive patients without IFN-AT acted as control group (Co-HCV+). Intracellular expression of IFNgamma and IL-4 was evaluated by multicolor flow-cytometry analysis in peripheral lymphocytes in vitro stimulated by phorbol-12-myristate-13-acetate (PMA) (25 ng/ml) and ionomycin (1 mug/ml) in presence of monensin (5 microm). RESULTS At the appearance of thyroid disease, both IFN-AT(Eu) and IFN-AT(Dy) patients showed a significant increase of IFNgamma expression in CD3+CD56+ and CD3-CD56+ cells but not in CD4+ and CD8+ cells. At this time point, IFN-AT(Eu) but not IFN-AT(Dy) patients also showed an increase of IL-4 expression in CD3+CD56+ cells and CD4+ cells. Six months later, IFN-AT(Eu) patients maintained high expression of IL-4 in CD4+ and CD3+CD56+ cells without any further increase in IFNgamma expression. By contrast, IFN-AT(Dy) patients showed an increase of IFNgamma expression in CD4+ and CD8+ cells, with a concomitant decrease of IL-4 expression in CD4+ cells. CONCLUSIONS Type 2 immune response is activated early and specifically in patients with IFN-AT who remain euthyroid throughout the follow-up. Predominant in patients developing thyroid dysfunction, by contrast, is the type 1 immune response that seems to occur earlier in innate than acquired immune system.

Abstract
We investigated whether intervention with antioxidant vitamins C and E in enteral feeding influenced oxidative stress and clinical outcome in critically ill patients. Two-hundred-sixteen patients expected to require at least 10 days of enteral feeding completed the study. One-hundred-five patients received enteral feeding supplemented with antioxidants, and 111 control patients received an isocaloric formula. Plasma lipoperoxidation (by thiobarbituric acid reactive substances [TBARS] and prostaglandin F(2alpha) isoprostane levels), low-density lipoprotein (LDL) oxidizability, and LDL tocopherol content were determined at baseline and at the end of the 10-day period. The clinical 28-day outcome was also assessed. Plasma TBARS and isoprostanes were 5.33 +/- 1.26 nM/mL and 312 +/- 68 pg/mL, respectively, before treatment and 2.42 +/- 0.61 nM/mL and 198 +/- 42 pg/mL after intervention (P < 0.01 for both comparisons). Antioxidants improved LDL resistance to oxidative stress by approximately 30% (the lag time before treatment was 87 +/- 23 min and was 118 +/- 20 min after treatment; P < 0.04). There was a significantly reduced 28-day mortality after antioxidant intervention (45.7% in the antioxidant group and 67.5% in the regular-feeding group; P < 0.05). Isoprostanes may provide a sensitive biochemical marker for dose selection in studies involving antioxidants.

Abstract
During tumor progression, the accumulation in genetic alterations is a fundamental characteristic of malignant cells. p53 gene is frequently mutated in human tumor. Cellular accumulation of p53 protein can initiate an immune response with generation of circulating anti-p53 antibodies. Patients with ulcerative colitis have an increased risk of developing colorectal neoplasm and, among the different genes involved in carcinogenesis, p53 may play a key role. Sera and tissues from 97 patients (M = 53, F = 44) affected with ulcerative colitis (UC) were collected. Serum anti-p53 antibodies (p53Abs) were detected in duplicate with ELISA method. Serum p53Abs were detectable in 9.3% (9/97) of patients affected with UC. In these patients, the titer of p53Ab ranged between 3.1 and 14.9 U/mL (mean, 6.6 U/mL; SD, 4.64). Serum p53Abs were undetectable in control group. With an immunoluminometric assay for the quantitative determination of p53, we found 9/97 positive samples (> or = 0.69 mg/mg of total proteins). In contrast, the samples of the remaining 89 patients were found negative (< or = 0.30 mg/mg of total proteins). All patients that were positive for anti-p53 antibodies were also positive with p53 protein accumulation in the tissue of colonic biopsies. In UC, follow-up with colonoscopy has several advantages. The colonoscopy is not well accepted by patients, and poor patient observance has the potential to seriously devalue the technique as a screening tool, despite practical considerations of competence within endoscopy service. Serological detection of p53Abs by enzyme-linked immunosorbent assay (ELISA) is easy to perform, does not require tumor specimen, can be performed in a routine diagnostic procedure, may be used in clinical practice, and could facilitate physicians in patient monitoring. We suggest that serum p53Abs assessment, indirect marker for p53 gene mutations, and abnormally high p53 protein levels could be considered to have a potential for use as a complementary test to improve surveillance program performance.

Abstract
Mutated p53 acts as a dominant oncogene and alterations in the p53 gene are described in a large number of patients with hepatocellular carcinoma (HCC). It has been demonstrated that hepatitis C virus (HCV)-core protein regulates transcriptionally cellular genes, as well as cell growth and apoptosis. This study was undertaken to evaluate whether p53 may be expressed also in a precocious stage of HCV-related liver damage. We studied p53 expression by immunoluminometric assay on liver samples from 40 patients (M/F 18/ 22, median age 44 years, range 13-64 years) with biopsy-proven HCV-related chronic hepatitis. We considered the following factors: degree of liver damage, liver iron content and HCV-RNA titre. We also evaluated as possible co-factors alcohol and food intake in the last 3 years. p53 was over-expressed in seven of 40 (17.5%) patients. Liver histology documented the presence of unexpected cirrhosis in two patients among the p53 positive subjects. The p53 positive group had a daily ethanol intake significantly higher in respect to that of the p53 negative group (P < 0.05). Alimentary history documented that patients with a p53 over-expression had a lower intake of total calories, monounsaturated fatty acids, vitamin C and riboflavin. Data indicate that p53 over-expression can occur even in initial stages of HCV-related liver disease.

Abstract
Helicobacter pylori is a definite carcinogen whose mechanism of action is still unknown. The aim of this work was (1) to determine the presence of p53 protein and related antibodies in patients affected by various gastric pathologies and chronically infected with H. pylori, and (2) to try to discover a test to be used as a marker of a possible switch towards a neoplastic phenotype.

Abstract
OBJECTIVES To compare the effect of a high-fat meal and a high-carbohydrate meal (pizza), with and without antioxidant vitamins, on endothelial activation in healthy subjects and in patients with type 2 diabetes mellitus. BACKGROUND The postprandial state is becoming increasingly acknowledged to affect some early events of atherogenesis. METHODS In a randomized, observer-blinded, crossover study, 20 newly diagnosed type 2 diabetic patients and 20 age- and gender-matched healthy subjects received two meals at one-week intervals: a high-fat meal (760 calories) and an isoenergetic high-carbohydrate meal (non-cheese pizza). In all subjects, the same meals were repeated immediately following ingestion of vitamin E, 800 IU, and ascorbic acid, 1,000 mg. RESULTS In normal subjects, the high-fat meal increased the plasma levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1), which were prevented by vitamins. No change in these parameters occurred after pizza ingestion or pizza ingestion with vitamins. In diabetic patients, basal concentrations of glucose, cytokines and adhesion molecules were significantly higher than in nondiabetic controls. Both meals significantly increased cytokine and adhesion molecule levels, but the increase was more sustained following the high-fat meal. There was no significant change from baseline when vitamin supplementation accompanied each meal. There was a relationship between changes in serum triglycerides and changes in TNF-alpha (r = 0.39, p < 0.01), IL-6 (r = 0.28, p < 0.05) and VCAM-1 (r = 0.25, p < 0.05), and between changes in plasma glucose and changes in IL-6 (r = 0.36, p < 0.01) and ICAM-1 (r = 0.31, p < 0.02). CONCLUSIONS An oxidative mechanism mediates endothelial activation induced by post-meal hyperlipidemia and hyperglycemia.

Abstract
OBJECTIVE The present study was undertaken to evaluate the pattern of serum cytokine production in postmenopausal women and the relationship with the hormonal status. A group of fertile women served as controls. METHODS Eighty-two women in apparent good health, non-smokers and without a history of hormone replacement therapy, were enrolled for the study. The women were divided in two groups according to their hormonal status: fertile women (n=34, age 32 +/- 7 years) and postmenopausal women (n=48, age 54 +/- 8 years). Blood samples were withdrawn in the morning, after an overnight fast. RESULTS Sex hormones (LH, FSH, Estradiol, Progesterone, DHEA, DHEA-S), as well as GH and IGF-1 levels, were significantly higher in the serum of fertile women as compared with their postmenopausal counterparts. Unlike IL-2, IL-4, IL-5, IL-10, IL-12 and IFN-gamma, significant differences were observed in serum IL-6, IL-18, TNFalpha and TNFbeta between groups: both IL-6 and IL-18 were higher in postmenopausal women, while TNFalpha and TNFbeta were significantly lower. There was an inverse relationship between serum DHEA and DHEA-S levels and both IL-6 (r= -0.46, P<0.02) or IL-18 (r= -0.38, P<0.05) serum concentrations. CONCLUSIONS Compared with fertile counterparts, women in postmenopause present an alteration in serum cytokine profile suggesting a prevalence of Th2 lymphocytes.

Abstract
BACKGROUND Visceral fat is a key regulator site for the process of inflammation, and atherosclerotic lesions are essentially an inflammatory response. METHODS AND RESULTS Fifty-six healthy premenopausal obese women (age range 25 to 44 years, body mass index 37.2+/-2.2, waist to hip ratio range 0.78 to 0.92) and 40 age-matched normal weight women were studied. Compared with nonobese women, obese women had increased basal concentrations of tumor necrosis factor-alpha (TNF-alpha, P<0.01), interleukin-6 (IL-6, P<0.01), P-selectin (P<0.01), intercellular adhesion molecule-1 (ICAM-1, P<0.02), and vascular adhesion molecule-1 (VCAM-1, P<0.05). Vascular responses to L-arginine (3 g IV), the natural precursor of nitric oxide, were impaired in obese women: reductions in mean blood pressure (P<0.02), platelet aggregation to adenosine diphosphate (P<0.05), and blood viscosity (P<0.05) were significantly lower as compared with those in the nonobese group. Concentrations of TNF-alpha and IL-6 were related (P<0.01) to visceral obesity, as well as to adhesin levels and responses to L-arginine. After 1 year of a multidisciplinary program of weight reduction (diet, exercise, behavioral counseling), all obese women lost at least 10% of their original weight (9.8+/-1.5 kg, range 7.5 to 13 kg). Compared with baseline, sustained weight loss was associated with reduction of cytokine (P<0.01) and adhesin (P<0.02) concentrations and with improvement of vascular responses to L-arginine. CONCLUSION In obese women, endothelial activation correlates with visceral body fat, possibly through inappropriate secretion of cytokines. Weight loss represents a safe method for downregulating the inflammatory state and ameliorating endothelial dysfunction in obese women.

Abstract
OBJECTIVE It is rare that manufacturers report age-related FT3, FT4 and TSH normal ranges in healthy children. STUDY DESIGN Using a solid phase time-resolved fluoroimmunometric method, we determined serum FT3, FT4 and TSH in 3,360 healthy children, age 2-16 years, that we grouped into two age ranges (2-7 yr and 9-16 yr). RESULTS Boys' and girls' mean serum thyroid hormone values substantially overlap in all age groups. In the age range 2-7 yr, FT3, FT4 and TSH values were 0.10-0.67 ng/dl (mean 0.37 ng/dl), range 0.45-2.29 ng/dl (mean 1.18 ng/dl) and 0.10-5.9 microU/ml (mean 2.2 microU/ml), respectively. In the age range 9-16 yr, FT3, FT4 and TSH values were 0.11-0.53 ng/dl (mean 0.35 ng/dl), 0.69-1.69 ng/dl (mean 1.07 ng/dl) and 0.20-6.1 microU/ml (mean 2.3 pU/ml), respectively. CONCLUSION Our results represent a useful set of reference values in children and can help physicians in the management of thyroid diseases.

Abstract
As reported earlier, p53 antibodies are detected in the sera of patients with different types of cancer, including lung cancer. In contrast, in the serum of healthy subjects the presence of anti-p53 antibodies is extremely rare. We collected the venous blood samples of 109 patients affected with lung cancer (LC): 57 patients (46 M, 11 F) with non-small-cell carcinoma (NSCLC), 52 others (40 M, 12 F) with small-cell carcinoma (SCLC). Serum p53 antibodies were assayed using ELISA method and all positive sera were confirmed by Western-blot method. In addition, using IRMA methods we assayed serum CEA, TPA, CYFRA21-1 and NSE. Serum p53Ab are detectable (p53Ab-positive) in 35/109 (32.1%) patients with lung cancer. About 17/57 (29.8%) patients affected with NSCLC and 18/52 (34.6%) with SCLC were p53Ab-positive. CEA, TPA, CYFRA21-1 and NSE sensitivity in LC patients (NSCLC+SCLC) is 50.5%, 58.7%, 42.2%, 35.8%, respectively. The lower sensitivity (32.1%) of serum p53Ab is connected with the higher specificity and diagnostic accuracy (100% and 69%, respectively). Out of 35 patients p53Ab-positive, five (14.3%) exhibit only serum p53Ab, while serum values of the established tumor markers were lower than cut-off. Serum p53Ab assessment is a simple and a low-cost assay with a good specificity and diagnostic accuracy that in LC patients can be used at least in association with established tumor markers.

Abstract
BACKGROUND The retinoblastoma-interacting zinc-finger gene RIZ is expressed in two forms (RIZ1 and RIZ2) that differ for the presence near the N-terminus of RIZ1 of a conserved domain, defined PR (PRDI-BF1-RIZ homology), homologous to a similar domain present in other proteins recognized as tumor suppressor gene products. The RIZ1 form is usually absent or expressed at low levels in tumor cells, whereas RIZ2 is frequently expressed. We investigated a possible involvement of RIZ1 in differentiation control using a myeloid cell maturation model that is easily modulated by retinoids and other agents. MATERIALS AND METHODS HL60 or NB4 cell lines or patients' leukemic promyelocytes were treated with all- trans -retinoic acid or other agents to induce differentiation. RIZ gene expression was determined with reverse transcriptase polymerase chain reaction (RT-PCR) and RNase protection assay. Immunocytochemistry was performed to assess variation of the intracellular distribution of RIZ protein on all- trans-retinoic acid treatment. Forced expression of RIZ1 protein was obtained with a recombinant adenovirus containing RIZ1 cDNA. RESULTS Treatment with retinoic acid induced a selective expression of RIZ1 in HL60 cell line. Retinoic acid effect was maximal at 7 days and correlated to the granulocytic differentiation of cells. A similar effect was obtained in retinoic acid-sensitive NB4 cell line or in patients' leukemic promyelocytes, but not in the retinoic acid-resistant cell line NB4.007/6 or in the U937 cell line. Selective expression of RIZ1 was also induced by 12-O-tetradecanoyl-phorbol-13-acetate in the U937 and HL60 cell lines and by 1,25-dihydroxyvitamin D(3) only in HL60 cells. In HL60 cells, RIZ1 was also induced by activation of a retinoid alpha receptor-independent maturation pathway based on retinoid X receptor agonist and protein kinase A synergism. In addition, retinoic acid produced a redistribution of the antigen within the nucleus in these cells. Forced expression of RIZ1 protein induced growth arrest and death of HL60 cells. CONCLUSIONS The correlation between the selective expression of RIZ1 induced by retinoic acid, 12-O-tetradecanoyl-phorbol-13-acetate, or 1,25-dihydroxyvitamin D(3) and differentiation suggested that RIZ protein was involved in myeloid cell differentiation induced by these agents.

Abstract
Estrogen treatment of MCF-7 cells grown in serum-free medium induced a modification of the intracellular distribution of p53 protein. Western blot analysis and immunofluorescence staining showed that p53 was localized in the nucleus of untreated cell and that after 48 h of hormone treatment, it was mostly localized in the cytoplasm. This effect was blocked by the antiestrogen ICI182,780. Intracellular redistribution of p53 was correlated to a reduced expression of the WAF1/CIP1 gene product and to the presence of degradation fragments of p53 in the cytosol. Estradiol treatment prevented the growth inhibition induced by oligonucleotide transfection, simulating DNA damage. This observation indicated that the wild-type p53 gene product present in the MCF-7 cell could be inactivated by estradiol through nuclear exclusion to permit the cyclin-dependent phosphorylation events leading to the G1-S transition. In addition, the estradiol-induced inactivation of p53 could be involved in the tumorigenesis of estrogen-dependent neoplasm.

Abstract
Co-immunoprecipitation experiments in cell extract from cultured cells or target tissues indicated that estrogen receptor was complexed with the retinoblastoma binding protein RIZ in a ligand-dependent manner. Mapping of interaction sites indicated that in both proteins the same regions and motifs responsible for the interaction of transcriptional co-activator and nuclear receptors were involved. In cultured cells, estradiol induced a redistribution of RIZ protein within the nucleus and in the cytoplasm. A similar effect was produced in vivo, in prepuberal rat endometrium, by administration of a physiological dose of estradiol. Therefore, RIZ protein could be a specific effector of estrogen action downstream of the hormone-receptor interaction, presumably involved in proliferation control.
