Abstract
BACKGROUND We studied the extent of BRCA1/2 genetic testing to help select the surgical approach for patients with breast cancer in Japan remains unclear. PATIENTS AND METHODS The study subjects were female patients with primary unilateral invasive breast cancer considered as candidates for breast-conserving surgery who underwent preoperative BRCA1/2 genetic testing. A retrospective analysis was performed on the results of BRCA1/2 genetic testing and surgical method selection using national registration data from the Japanese Hereditary Breast and Ovarian Cancer Syndrome Consortium. RESULTS Our study included 318 female patients. Among these patients, 23.7% of patients with BRCA1/2 mutations and 61.8% of patients without these variants underwent breast-conserving surgery (P < .01). Among the patients with BRCA1/2 mutations, those who chose breast-conserving surgery tended not to undergo risk-reducing salpingo-oophorectomy (P < .05). Among the patients with BRCA1/2 mutations who underwent mastectomy for the affected side, 31.8% received contralateral risk-reducing mastectomy. Patients diagnosed with breast cancer under the age of 50 years were more likely to have contralateral risk-reducing mastectomy than patients over the age 50 years (P < .05). CONCLUSIONS Patients with BRCA1/2 mutations tend to choose mastectomy. However, it is speculated that the final surgical method selection is made in consideration of not only the test results but also with careful consideration of the patient, taking into account other factors including individual values for risk-reducing surgeries and the age of breast cancer onset.

Abstract
Panel sequencing of susceptibility genes for hereditary breast and ovarian cancer (HBOC) syndrome has uncovered numerous germline variants; however, their pathogenic relevance and ethnic diversity remain unclear. Here, we examined the prevalence of germline variants among 568 Japanese patients with BRCA1/2-wildtype HBOC syndrome and a strong family history. Pathogenic or likely pathogenic variants were identified on 12 causal genes for 37 cases (6.5%), with recurrence for 4 SNVs/indels and 1 CNV. Comparisons with non-cancer east-Asian populations and European familial breast cancer cohorts revealed significant enrichment of PALB2, BARD1, and BLM mutations. Younger onset was associated with but not predictive of these mutations. Significant somatic loss-of-function alterations were confirmed on the wildtype alleles of genes with germline mutations, including PALB2 additional somatic truncations. This study highlights Japanese-associated germline mutations among patients with BRCA1/2 wildtype HBOC syndrome and a strong family history, and provides evidence for the medical care of this high-risk population.

Abstract
Recently, olaparib(brand name: Lynparza Tablets)-a PARP inhibitor-has been approved for national health insurance coverage in Japan as a drug for unresectable or recurrent, BRCA1/2-positive, HER2-negative breast cancer in patients with a history of cancer chemotherapy. The addition of BRCA1/2 genetic testing as a companion diagnostic tool to the health insurance coverage is of considerable significance as a spearhead of health insurance medical care for all different types of hereditary tumors. However, several problems related to this companion diagnostic test have emerged, including the estab- lishment of a genetic counseling system and handling of BRCA1/2 genetic tests performed at the patients' own expense. In addition, the purpose of the companion diagnostic test is to confirm drug indication in a case. However, since the test results include the diagnosis of hereditary tumors, there is also an urgent need to improve the medical care system and social environment for family members of patients with pathological mutations. The use of genetic analysis is widespread in the clinical settings, and genetic medical care is anticipated to advance in the future. Therefore, it would be pivotal to come up with measures against hereditary tumors, such as hereditary breast and ovarian cancer(HBOC)syndrome. In this chapter, we describe the current status and prospects of HBOC medical care, with a particular focus on companion diagnostics.

Abstract
Background: BRCA1 and BRCA2 are high-penetrance inherited genes; different founder mutations have been reported in various areas and races. By using trial registration data from the Japanese hereditary breast and ovarian cancer syndrome (HBOC) consortium, we aimed to explore the clinicopathological characteristics of breast cancer patients with the Japanese founder mutation BRCA1 L63X. Results: We found 88 BRCA1 carriers, 76 BRCA2 carriers, and one carrier of both BRCA1 and BRCA2. Of 46 independent BRCA1 mutations, the BRCA1 L63X mutation was detected in 26 patients. We observed a significant difference in the proportion of triple-negative breast cancer phenotype among 88.9%, 72.5%, and 26.8% of BRCA1 L63X mutation, BRCA1 mutation, and BRCA2 mutation carriers, respectively (p < .001). Additionally, significant differences were also observed in nuclear grade in the resultant breast cancer between the groups (p < .001). Conclusions: A high proportion of Japanese HBOC patients showed the BRCA1 L63X mutation, and the clinical characteristics of breast cancer in patients with this mutation might differ from those in patients with other BRCA1 or BRCA2 mutations, in terms of the subtype and nuclear grade of the resultant cancer. Methods: From 827 patients in the Japanese HBOC consortium through August 2015, patients with BRCA1/2 mutations were included in this study. We compared the clinicopathological features among patients with BRCA1 L63X mutation, other BRCA1 mutations, and BRCA2 mutations using Chi-square test.

Abstract
Background Ductal carcinoma in situ (DCIS) is considered a component of the clinical spectrum of breast cancer even in those with BRCA1/2 mutation. The aim of this study was to report the feature of DCIS raised in Japanese women with BRCA1/2 mutations. Methods A total of 325 Japanese women with breast cancer (BC) (with or without invasive cancer) were referred for genetic counseling and underwent genetic testing for mutations in the BRCA1 and BRCA2 genes in Showa University Hospital between December 2011 and August 2016. And 49 of them who were pathologically diagnosed as DCIS were included in this study. Logistic regression models were fit to determine the associations between potential predictive factors and BRCA status. A Cox proportional hazards model is used to predictive value of parameters for Ipsilateral breast tumor recurrence (IBTR) and contralateral breast tumor recurrence (CBTR). Results (a) Of 325 patients (with or without invasive cancer), 19.1% (62/325) tested positive for BRCA1/BRCA2 mutations. And 18.4% (9/49) was positive for BRCA1/BRCA2 mutations in DCIS, compared with 19.2% (53/276) in IDC (p = 1.000). Among BRCA mutations, 14.5% (9/62) had DCIS compared with nonmutations (15.2%, 40/263). Incidence of DCIS was 3.0% (1/33) of BRCA1 mutations and 27.5% (8/29) of BRCA2 mutation (p = 0.009). (b) Median age of diagnosis in BRCA mutation carriers was 39 years, compared with 46 years in noncarriers. Age, Family history (FH) of BC, FH of first or second BC and total number of relatives with BC diagnosis (DX) has significant difference between BRCA mutation carriers and noncarriers in univariate analysis. In a multivariate logistic model, total relatives with BC DX ≥ 2 (odds ratio [OR], 5.128; 95% confidence interval [CI], 1.266–20.763; p = 0.022), age at diagnosis ≤35 years (OR 0.149, 95% CI 0.023–0.954, p = 0.045) and ER+/HER2+ status (OR 5.034, 95% CI 1.092–23.210, p = 0.038) remained as independent significant predictors for BRCA mutation. Ki67 index (cut off by 14% or 30%) did not differ between BRCA mutation carriers and noncarriers (p = 0.459 and p = 0.651). (c) There was a significant difference in ER‐positive tumors among BRCA2 carriers and noncarriers (p = 0.042). Subgroup analysis showed BRCA2 carriers tend to be of higher grade (Grade 2 and 3), more frequently ER+/PR+ (p = 0.041) and lower proliferation (Ki67 index) than noncarriers, whereas differences in nuclear grade and ki67 index were not found significantly in our study. (d) BRCA mutation was not associated with an increased risk of IBTR and CBTR. Conclusion DCIS is equally as prevalent in patients who were BRCA mutation carriers as in high familial‐risk women who were noncarriers, but occurs at earlier age. BRCA2 carriers have higher incidence in DCIS than that of BRCA1 carriers, and tend to be higher grade and more frequently ER positive and lower proliferation. Total relatives with BC DX ≥2, age at diagnosis ≤35 years and ER+/HER2+ might be independent predictors for BRCA mutation in Japanese women with DCIS and patients of these risk factors should be recommended to receive genetic counseling and BRCA testing.

Abstract
The purpose of this study is to summarize the results from a survey on awareness of genetic counseling for pregnant women who wish to receive non-invasive prenatal testing (NIPT) in Japan. As a component of a clinical study by the Japan NIPT Consortium, genetic counseling was conducted for women who wished to receive NIPT, and a questionnaire concerning both NIPT and genetic counseling was given twice: once after pre-test counseling and again when test results were reported. The responses of 7292 women were analyzed. They expressed high satisfaction with the genetic counseling system of the NIPT Consortium (94%). The number of respondents who indicated that genetic counseling is necessary for NIPT increased over time. Furthermore, they highly valued genetic counseling provided by skilled clinicians, such as clinical geneticists or genetic counselors. The vast majority (90%) responded that there was sufficient opportunity to consider the test ahead of time. Meanwhile, women who received positive test results had a poor opinion and expressed a low-degree satisfaction. We confirmed that the pre-test genetic counseling that we conducted creates an opportunity for pregnant women to sufficiently consider prenatal testing, promotes its understanding and has possibilities to effectively facilitate informed decision making after adequate consideration. A more careful and thorough approach is considered to be necessary for women who received positive test results.

Abstract
22 Background: Hereditary breast and ovarian cancer (HBOC) is a high-penetrance inherited disease, and founder mutation has been reported in the West. However, there are yet no reports of founder mutation of HBOC on breast cancer in the Japanese population. In this study, we report the breast cancer clinical characteristics of L63X, which is one of the founder mutations in BRCA1 in the Japanese population. Methods: Data on 223 affected breast cancer patients (28 BRCA1 carriers, 19 BRCA2 carriers, and 176 non-carriers) were collected at Showa University in Tokyo from September 2010 to June 2015. In 22 independent mutations of BRCA1, the L63X mutation was detected in 9 patients. Data regarding the age of breast cancer onset, pathological features, clinical features, and family history were collected. Results: The age of onset was no significant differences between the L63X mutation and other BRCA1 mutations (39.7 vs. 38.5years). The proportion of triple negative breast cancer patients was 87.5% in the L63X mutation carriers and 89.5% in other BRCA1 mutation carriers. No patients of the L63X affected bilateral breast cancers. On the other hand, 36.7% of other BRCA1mutations affected bilateral breast cancers. There was no significant difference in pathological features (intrinsic subtype, nuclear grade and ki-67 index). The L63X carriers tended to have a family history of breast cancers. All L63X mutations were detected in the Eastern part of Japan. Conclusions: The breast cancer clinical characteristics of L63X might be considered no different from other types of BRCA1 mutations. Recently, it has been reported that breast and ovarian cancer risks varied according to the type and location of BRCA1/2 mutations. L63X mutation is located in the breast cancer cluster region in BRCA1. Further investigation is necessary for appropriate validation and accumulation of data.

Abstract
To clarify the role of human papillomavirus (HPV) and Epstein-Barr virus (EBV) infection in gastric carcinogenesis in relation to overexpression of mutated p53 anti-oncogene, we used PCR to amplify DNA sequences of these viruses and immunohistochemistry to detect p53 overexpression in formaline-fixed, paraffin embedded blocks including 12 normal gastric and 51 gastric carcinoma specimens. HPV and EBV DNA were found in 17% and 0% of normal gastric tissues and in 45% and 27% of gastric carcinoma specimens, respectively. p53 overexpression was shown in 37% of gastric carcinoma specimens only. HPV infection rate was significantly higher in stage I gastric carcinomas as compared with stage IV carcinomas (p<0.03). p53 overexpression was significantly increased in well-differentiated adenocarcinomas as compared with poorly differentiated carcinomas (p<0.01). The rates of both HPV infection and p53 overexpression were significantly higher in gastric carcinomas without vascular invasion than in those with the invasion (p<0.02). No correlation was found between p53 overexpression and/or the presence of viral DNA (HPV/EBV) in regard to the depth of invasion, lymph node involvement, distant metastasis, and the location of the tumors. Our results suggest that some of the gastric carcinomas are associated with HPV and/or EBV infection and p53 mutations, and that all of these may be involved in the early stage of this malignancy. There was no correlation between HPV and or EBV infection and overexpression of p53 in gastric carcinoma.

Abstract
We present azimuthal angle correlations of intermediate transverse momentum (1-4 GeV/c) hadrons from dijets in Cu+Cu and Au+Au collisions at square root sNN=62.4 and 200 GeV. The away-side dijet induced azimuthal correlation is broadened, non-Gaussian, and peaked away from Delta phi=pi in central and semicentral collisions in all the systems. The broadening and peak location are found to depend upon the number of participants in the collision, but not on the collision energy or beam nuclei. These results are consistent with sound or shock wave models, but pose challenges to Cherenkov gluon radiation models.

Abstract
Cross sections for midrapidity production of direct photons in p+p collisions at the Relativistic Heavy Ion Collider (RHIC) are reported for transverse momenta of 3 < pT < 16 GeV/c. Next-to-leading order perturbative QCD (pQCD) describes the data well for pT >5 GeV/c, where the uncertainties of the measurement and theory are comparable. We also report on the effect of requiring the photons to be isolated from parton jet energy. The observed fraction of isolated photons is well described by pQCD for pT >7 GeV/c.

Abstract
Deuteron-gold (d+Au) collisions at the Relativistic Heavy Ion Collider provide ideal platforms for testing QCD theories in dense nuclear matter at high energy. In particular, models suggesting strong saturation effects for partons carrying small nucleon momentum fraction (x) predict modifications to jet production at forward rapidity (deuteron-going direction) in d+Au collisions. We report on two-particle azimuthal angle correlations between charged hadrons at forward/backward (deuteron/gold going direction) rapidity and charged hadrons at midrapidity in d+Au and p+p collisions at square root of sNN=200 GeV. Jet structures observed in the correlations are quantified in terms of the conditional yield and angular width of away-side partners. The kinematic region studied here samples partons in the gold nucleus with x~0.1 to ~0.01. Within this range, we find no x dependence of the jet structure in d+Au collisions.

Abstract
J/psi production in d + Au and p + p collisions at square root of S(NN) = 200 GeV has been measured by the PHENIX experiment at rapidities -2.2 < y < +2.4. The cross sections and nuclear dependence of J/psi production versus rapidity, transverse momentum, and centrality are obtained and compared to lower energy p + A results and to theoretical models. The observed nuclear dependence in d + Au collisions is found to be modest, suggesting that the absorption in the final state is weak and the shadowing of the gluon distributions is small and consistent with Dokshitzer-Gribov-Lipatov-Altarelli-Parisi-based parametrizations that fit deep-inelastic scattering and Drell-Yan data at lower energies.

Abstract
We report on charged hadron production in deuteron-gold reactions at sqrt[s(NN)]=200 GeV. Our measurements in the deuteron direction cover 1.4<eta<2.2, referred to as forward rapidity, and in the gold direction -2.0<eta<-1.4, referred to as backward rapidity, and a transverse momentum range p(T)=0.5-4.0 GeV/c. We compare the relative yields for different deuteron-gold collision centrality classes. We observe a suppression relative to binary collision scaling at forward rapidity, sensitive to low momentum fraction (x) partons in the gold nucleus, and an enhancement at backward rapidity, sensitive to high momentum fraction partons in the gold nucleus.

Abstract
We present a measurement of the double longitudinal spin asymmetry in inclusive pi(0) production in polarized proton-proton collisions at sqrt[s]=200 GeV. The data were taken at the Relativistic Heavy Ion Collider with average beam polarizations of 0.27. The measurements are the first in a program to study the longitudinal spin structure of the proton, using strongly interacting probes, at collider energies. The asymmetry is presented for transverse momenta 1-5 GeV/c at midrapidity, where next-to-leading-order perturbative quantum chromodynamic (NLO pQCD) calculations well describe the unpolarized cross section. The observed asymmetry is small and is compared to a NLO pQCD calculation with a range of polarized gluon distributions.

Abstract
Transverse momentum spectra of charged hadrons with p(T)<8 GeV/c and neutral pions with p(T)<10 GeV/c have been measured at midrapidity by the PHENIX experiment at BNL RHIC in d+Au collisions at sqrt[s(NN)]=200 GeV. The measured yields are compared to those in p+p collisions at the same sqrt[s(NN)] scaled up by the number of underlying nucleon-nucleon collisions in d+Au. The yield ratio does not show the suppression observed in central Au+Au collisions at RHIC. Instead, there is a small enhancement in the yield of high momentum particles.

Abstract
A 20-year-old woman presented with a 4-month history of follicular papules distributed over the trunk and extremities. One month later, routine blood tests were abnormal, showing acute myeloblastic leukaemia (M1 in the French-American-British classification). Skin biopsy demonstrated a dermal infiltrate of a large number of neutrophils with occasional eosinophils and histiocytes in the vicinity of the hair follicle remnants. Intermingled in the infiltrate were atypical cells that were morphologically and immunohistochemically identical to leukaemic myeloblasts. Cultures of the papules and special stains of the biopsy specimen were negative for bacteria and fungi. The follicular eruption improved promptly in response to chemotherapy for the leukaemia. We suggest that this case may represent a rare, follicular variant of neutrophilic dermatosis associated with myelogenous leukaemia.

Abstract
We report the result of enzymatic and molecular analyses, using cultured lymphocyte fractions (cultivated monocytes), of six Japanese patients (from five families) and one Italian patient with fructose-1,6-bisphosphatase (FBPase) deficiency. Enzymatic analysis demonstrated FBPase deficiency in all seven patients, including the Italian patient whose fructose-1,6-bisphosphatase activity has been reported to be normal in leukocytes but deficient in liver. Molecular analysis of the FBPase gene identified pathogenic mutations in only 8 among the total 12 alleles of six families. We have thus demonstrated the validity of using cultured monocytes as a secure and noninvasive alternative to liver biopsy for accurate diagnosis of FBPase deficiency.

Abstract
A 71-year-old Japanese woman presented with erythematous plaques on the eyelids and subcutaneous indurations or nodules with or without overlying erythema on the hands, thigh, and leg. She also had oral ulcers, arthralgia and a low grade fever. Laboratory tests revealed an elevated titer of antinuclear antibody, an increased erythrocyte sedimentation rate and anemia. Skin biopsy specimens from the hand and thigh showed lymphocytic perivascular and periappendageal infiltrates and vacuolar alterations at the basement membrane zone of the skin appendages. Moreover, there was a dense lymphocytic infiltrate deep in the dermis with extension into the subcutaneous fat, which was compatible with the diagnosis of lupus erythematosus profundus. Although the biopsy specimen from the eyelid lesion did not contain the subcutaneous fat, the changes in the dermis were essentially the same as those of the hand and thigh. The eruption as well as the other symptoms promptly responded to oral prednisolone.

Abstract
A 53-year-old female with a 9-month history of chest pain presented with a giant anterior chest wall mass. Radiologic examination showed an anterior mediastinal tumor invading the chest wall. Serum calcium and parathyroid hormone-related protein (PTHrP) levels were extremely elevated. Biopsy specimens disclosed a squamous cell carcinoma with Hassall's corpuscle-like keratotic pearls, and an immunohistological study showed a positive staining with PTHrP. The tumor and serum PTHrP concentration markedly decreased following cisplatin-based chemotherapy and radiation. This is the first case of PTHrP producing a thymic carcinoma with the unusual presentation of a large extrathoracic mass.

Abstract
Fructose-1,6-bisphosphatase (FBPase) is a key gluconeogenic enzyme. The data herein show that both the enzyme activity and mRNA level of the human FBPase gene are enhanced by 9-cis retinoic acid (9cRA) and all-trans retinoic acid (atRA) as well as by 1,25-dihydroxyvitamin D3 (VD3) in human promyelocytic HL60 cells and normal monocytes in peripheral blood, which were used as an alternative source to liver for the DNA diagnosis of FBPase deficiency. To understand the molecular mechanism of this enhancing action, the 2.4 kb 5'-regulatory region of the human FBPase gene was isolated and sequenced. Using luciferase reporter gene assays, a 0.5 kb FBPase basal promoter fragment was found to confer induction by VD3, 9cRA, and atRA that was mediated by the vitamin D3 receptor (VDR), retinoid X receptor (RXR), and retinoic acid receptor (RAR). Within this region, a direct repeat sequence, 5'-TAACCTttcTGAACT-3' (-340 to -326), which functions as a common response element for VD3, 9cRA, and atRA, was identified. The results of electrophoretic mobility shift assays indicated that VDR-RXR and RAR-RXR heterodimers bind this response element. Collectively, these observations indicate that VD3 and RA are important modulators of the expression of the human FBPase gene in monocytic cells.

Abstract
p27Kip1, a cyclin-dependent kinase inhibitor, is a negative regulator of the cell cycle, and apoptosis is a genetically encoded program of cell death. To clarify the relationship between the cell cycle and apoptosis, we investigated expression of p27, cyclin D1 and apoptosis-related proteins (p53, Bax, Bcl-2 and c-Myc) in 60 cases of oral and oropharyngeal squamous-cell carcinoma (SCC) using an immuno-histochemical approach, and evaluated spontaneous apoptosis in vivo. Our most notable finding was that spontaneous apoptosis in the p27-positive group was significantly higher than that in the p27-negative group (p = 0.028). In addition, the percentage of p27-positive cells was clearly correlated with that of Bax-positive cells (gamma = 0.288, p = 0.028) and with that of cyclin D1-positive cells (gamma = 0.416, p = 0.002). Expression of p27 was inversely associated with the clinical stage of total tumor progression (p = 0.027). However, no correlation was found between p27 expression and the following parameters: gender, tumor size, lymph node metastasis, overall survival and disease-free survival. Our results give evidence that the action of the cell-cycle regulator p27 is closely linked with apoptosis in clinical samples from patients and indicate that over-expression of p27 might induce apoptosis in cancer cells through elevation of Bax expression, thereby acting on tumor progression.

Abstract
Fructose-1,6-bisphosphatase (FBPase) deficiency is an autosomal recessive inherited disorder and may cause sudden unexpected infant death. We reported the first case of molecular diagnosis of FBPase deficiency, using cultured monocytes as a source for FBPase mRNA. In the present study, we confirmed the presence of the same genetic mutation in this patient by amplifying genomic DNA. Molecular analysis was also performed to diagnose another 12 Japanese patients with FBPase deficiency. Four mutations responsible for FBPase deficiency were identified in 10 patients from 8 unrelated families among a total of 13 patients from 11 unrelated families; no mutation was found in the remaining 3 patients from 3 unrelated families. The identified mutations included the mutation reported earlier, with an insertion of one G residue at base 961 in exon 7 (960/961insG) (10 alleles, including 2 alleles in the Japanese family from our previous report [46% of the 22 mutant alleles]), and three novel mutations--a G-->A transition at base 490 in exon 4 (G164S) (3 alleles [14%]), a C-->A transversion at base 530 in exon 4 (A177D) (1 allele [4%]), and a G-->T transversion at base 88 in exon 1 (E30X) (2 alleles [9%]). FBPase proteins with G164S or A177D mutations were enzymatically inactive when purified from E. coli. Another new mutation, a T-->C transition at base 974 in exon 7 (V325A), was found in the same allele with the G164S mutation in one family (one allele) but was not responsible for FBPase deficiency. Our results indicate that the insertion of one G residue at base 961 was associated with a preferential disease-causing alternation in 13 Japanese patients. Our results also indicate accurate carrier detection in eight families (73%) of 11 Japanese patients with FBPase deficiency, in whom mutations in both alleles were identified.

Abstract
pMRA17 cloned from Pseudomonas K-62 plasmid pMR26 specified the resistance to both organic and inorganic mercurials. DNA sequence of this broad-spectrum resistant mer operon was determined. The 5504-bp sequence includes six open reading frames (ORFs), five of which were identified as merR, merT, merP, merA and merB in order by analysis of deletion mutants and by comparison with the DNA and amino acid (aa) sequences of previously sequenced mer operons. The merB encoding organomercurial lyase showed a less identity than the other mer genes with those from other broad-spectrum resistance operons. The remaining ORF named merE, located between merA and merB, had no significant homology with the published mer genes and seemed to be a new gene which may involve in phenylmercury resistance. Induction experiments and maxicell analyses of the mer-polypeptides revealed that pMRA17 mer operon expressed mercurial-inducible phenotype and the merB and merE as well as the merA were under the control of MerR which could activate not only by mercuric ion but also by organomercurials.

Abstract
Gastrin-releasing peptide (GRP) is present in the lung and functions as a growth factor for bronchial epithelial cells and fibroblasts. GRP may stimulate release of cytokines from alveolar macrophages. However, in interstitial lung diseases, the role of GRP has not been clarified, in part because of the instability of GRP. Progastrin-releasing peptide (ProGRP) molecules are the actual GRP gene products. ProGRP molecules contain common extension peptides(31-98) [ProGRP(31-98)], which are not homologous with other proteins unlike GRP. With the ELISA, we measured ProGRP(31-98) concentrations in sera and bronchoalveolar lavage (BAL) fluids from patients with sarcoidosis and idiopathic pulmonary fibrosis (IPF). Significant increased ProGRP(31-98) concentrations were found in sera and BAL fluids from patients with IPF or sarcoidosis when compared with healthy subjects. Serum ProGRP(31-98) values significantly correlated with BAL fluid ProGRP(31-98) values. In IPF and sarcoidosis, the release of the actual GRP gene products is increased in the lung and the bloodstream, and GRP may play a role during the processes of inflammation and remodeling in interstitial lung diseases.

Abstract
Inactivation of p53 gene products either by mutation or by complex formation with E6 oncoprotein encoded by high risk HPV appears to be a common event in cervical carcinogenesis. This study was designed to clarify this association in 41 primary cervical, 15 endometrial, 3 ovarian and one rectal carcinomas. Polymerase chain reaction analysis revealed presence of high risk HPV in 36 (88%) cervical, 5 (33%) endometrial and none of ovarian and rectal carcinomas. HPV 16 was found in 14 cervical carcinomas, HPV 18 in 19 cervical and 2 endometrial carcinomas and HPV 33 in 28 cervical and 5 endometrial carcinomas. Expression of tumor suppressor protein p53 by using polyclonal antibody CM-1, was detected in 28 (68%) cervical, 7 (47%) endometrial, 2 (66%) ovarian and one (100%) rectal carcinoma. Twenty six cervical and 3 endometrial carcinoma cases were positive for both high risk HPV and p53. We conclude that beside cervical carcinoma HPV infection is not uncommon in endometrial carcinoma and in our experimental design there is no inverse correlation between HPV infection and p53 over-expression in a variety of the tumors analysed in the present study.

Abstract
This study was undertaken to examine the role of proteases in etoposide-induced apoptosis of human leukemia HL-60 cells. We found the potent activity to produce internucleosomal DNA fragmentation in a 150 000 g supernatant of cell lysate which was prepared from etoposide-treated HL-60 cells undergoing apoptosis. This nuclear-DNA fragmenting activity could be detected when the supernatant was incubated with isolated nuclei under Mg2+-dependent conditions. On the other hand, we could not detect such activity in the supernatant of cell lysate from non-treated HL-60 cells. Treatment of the supernatant with a serine protease inhibitor, N-tosyl-L-phenylala-nylchloromethyl ketone (TPCK), abolished the DNA fragmenting activity. An inhibitor of interleukin 1-beta-converting enzyme (ICE), Z-Val-Ala-Asp-fluoromethyl ketone (VAD-FMK), had no effect on this DNA fragmenting activity in vitro. However, when the cells were incubated with etoposide in the presence of VAD-FMK, the formation of TPCK-sensitive DNA fragmenting activity was blocked. Our data indicate that serine and ICE-like proteases may be involved in etoposide-induced apoptosis at the different stages, and especially a serine protease may be closely associated with the final step for induction of internucleosomal DNA fragmentation during apoptosis in HL-60 cells.

Abstract
The process of tumor growth and metastasis is a complex cascade of events relating many factors. The adhesion molecules relate to the cell-cell adhesion, adhesion to the extracellular matrix or the vascular endothelium and are thought to play important roles in the invasion and metastasis of the cancer. Integrins are known as extracellular matrix receptors. The change in the expression of integrins in the cancer cells has been reported. Recent information on the role of integrins in tumor progression and metastasis is reviewed here.

Abstract
Tumor cell interaction with extracellular matrix and endothelial cells constitute the most crucial factor of metastasis. Integrins are one of adhesion molecules which mediate the interaction. Most lung cancers adhered strongly to extracellular matrix corresponding with expression of integrins. Three lung cancers which expressed few or no integrins had very weak ability to adhere to extracellular matrix. Strong binding to endothelial cells was found in most lines but the three lung cancers had very little ability to adhere to endothelial cells. Binding to endothelial cells were strongly inhibited by antibodies to beta-1 subunit. Lung cancers may adhere to extracellular matrix and endothelial cells through integrins, especially the beta-1 subfamily.

Abstract
Fructose-1,6-bisphosphatase deficiency is an inheritable disorder of gluconeogenesis. Sequence analysis of the cDNA of the fructose-1,6-bisphosphatase mRNA isolated from monocytes from a girl with this disease and her consanguineous parents revealed that the patient and her parents were a homozygote and heterozygotes for an insertion of one G residue at G957GGGG961, respectively. This mutation resulted in translation of a truncated enzyme protein, and the mutant protein showed no fructose-1,6- bisphosphatase activity in an overexpression experiment in Escherichia coli. However, this mutation is located in a region of the amino acid sequence which is not well conserved among mammals. A mutagenized clone was prepared from the normal clone. The extents of substitutions and deletions of the amino acid sequence were predicted to be less in the mutagenized protein than in the mutant protein. This mutagenized clone also expressed no fructose-1,6-bisphosphatase activity, although both of two normal clones from control monocytes and a control liver sample expressed an apparently normal level of fructose-1,6-bisphosphatase activity. Thus, this mutation is concluded to be responsible for fructose-1,6-bisphosphatase deficiency in this patient.

We investigated phenotypic surface markers of peripheral blood lymphocytes including expression of gamma delta T cell receptor (TCR gamma delta) in 185 patients with sarcoidosis and 42 normal subjects. The proportion of TCR gamma delta+ lymphocytes in peripheral blood of patients with sarcoidosis (5.5 +/- 5.4%) was significantly higher than in normal subjects (3.6 +/- 2.2%; p < 0.05). A number of patients with sarcoidosis had prominently increased levels of circulating TCR gamma delta+ lymphocytes. Successive measurements of circulating TCR gamma delta+ lymphocytes demonstrated the persistence of increased levels of circulating TCR gamma delta+ lymphocytes. We divided the patients with sarcoidosis into two groups, one with high, the other with low TCR gamma delta+ expression. Compared with the low-value group, the high-value group had significantly decreased levels of circulating CD4+ lymphocytes, decreased incidence of a positive tuberculin reaction, and higher levels of serum angiotensin-converting enzyme and lysozyme, suggesting that these two groups may differ in their immunological response and disease activity of sarcoidosis. Measurement of TCR gamma delta+ expression in the circulation seems to be useful for estimating the disease activity of sarcoidosis.

Abstract
We measured eosinophilic cationic protein (ECP) concentrations in the circulation and bronchoalveolar lavage (BAL) fluids from patients with chronic eosinophilic pneumonia, patients with eosinophilic granuloma, and normal control subjects. Significantly increased ECP concentrations were found in the circulation of patients with chronic eosinophilic pneumonia and with eosinophilic granuloma compared with those found in control subjects. The ECP concentrations were well correlated to eosinophil counts in the circulation of patients with chronic eosinophilic pneumonia, while they were not in patients with eosinophilic granuloma. Chronic eosinophilic pneumonia patients had prominently increased ECP concentrations in BAL fluids compared with those found in control subjects, while eosinophilic granuloma patients did not. Those concentrations in chronic eosinophilic pneumonia patients were well correlated to eosinophil counts in the BAL fluid. Corticosteroid therapy remarkably decreased circulating ECP concentrations in three patients with chronic eosinophilic pneumonia, but it had no significant effects in two patients with eosinophilic granuloma. Measurement of ECP concentrations seems to be useful to evaluate the disease activity of chronic eosinophilic pneumonia.

Abstract
Intercellular adhesion molecule 1 (ICAM-1) plays an important role in inflammatory diseases. We investigated levels of circulating soluble ICAM-1 in patients with miliary tuberculosis (n = 8) and pulmonary tuberculosis (n = 49). We also attempted to compare ICAM-1 levels among pulmonary tuberculosis patients according to chest X ray classification of the Japanese Society for Tuberculosis. Significantly increased levels of circulating ICAM-1 were found in patients with miliary tuberculosis and extensive (extent 3) pulmonary tuberculosis (n = 9) compared to those of controls (n = 48), but not in patients with extent 1 (n = 24) or extent 2 pulmonary tuberculosis (n = 16). Immunohistochemical examination of the tuberculous lung tissues from the patients showed intensive cellular ICAM-1 on epithelioid cells and giant cells as well as on vascular endothelial cells. These results suggest that ICAM-1 is an important adhesion molecule in tuberculosis.

Abstract
Fructose 1,6-bisphosphatase deficiency is an autosomal recessive inherited disorder of gluconeogenesis. We could isolate cDNAs encoding human fructose 1,6-bisphosphatase from normal monocytes, liver and kidney, but not from normal lymphocytes. The cDNAs contained an open reading frame coding for 338 amino acids, and their nucleotide sequences in monocytes and liver were identical. G644C645 nucleotides in this sequence were the same as those of cDNA from HL-60 cells, although our result differed from a previous report (M. El-Maghrabi et al. (1993) J. Biol. Chem. 268, 9466-9472) on an alteration to C644G645 nucleotides in human liver cDNA resulting in a change of Gly-214 to Ala-214 in the enzyme. The Gly-214 (GGC) residue was therefore conserved in the enzymes hitherto isolated from humans and other animals. Analysis of monocytes in seven patients with fructose 1,6-bisphosphatase deficiency showed a DNA fragment with apparent normal size in two sisters but no detectable DNA fragment in the other five patients. Monocytes were thus useful as an alternative source for mRNA from human liver for the molecular analysis of fructose 1,6-bisphosphatase deficiency.

Abstract
In 68 cases of surgically resected gastric carcinomas, expression of human epidermal growth factor (EGF) and its receptor (EGFR) were examined immunohistologically using the Avidin-Biotin Peroxidase Complex Method, and their relation with DNA contents and nuclear protein synthesis in the tumor progression were studied by measuring DNA ploidy patterns and nucleolar organizer regions (NORs), respectively with cytofluorometry and AgNO3 stain method. EGF and EGFR expression were respectively found only in 2 (7%) and 1 (4%) in 28 early cancers, and significantly increased in advanced cancers, 25 (63%) and 9 (23%) out of 40 cases. The ratio of aneuploid tumor and the NORs numbers per tumor cell also increased in advanced cancers, compared with in early cancers. EGF and EGFR respectively expressed in 19 (51%) and 9 (23%) in 37 aneuploid cancers, significantly more frequent than 8 (26%) and 1 (3%) in 31 diploid cancers. In the EGF-positive tumors, the NORs numbers showed 4.11 +/- 0.72, significantly higher than 2.68 +/- 0.61 in the EGF-negative tumors. These results suggested that expression of EGF and EGFR in the gastric carcinomas increases during the tumor progression from the early to advanced stage, stimulates synthesis of DNA and nuclear protein, and consequently enhances (strengthens, heightens, or intensifies) the proliferative activity of the tumors.

Abstract
Rel proteins have been implicated in the differentiation and transformation of lymphoid cells. Despite their significant sequence homology to the Drosophila Dorsal morphogen, a functional role for Rel proteins in early development has yet to be established. Here we show that expression of the v- or c-rel genes in P19 embryonal carcinoma (EC) cells leads to drastic morphological changes accompanied by the expression of several differentiation-specific antigens. In contrast, v-Rel mutants defective for DNA-binding as well as those lacking the F9 cell-specific transcription activation region of v-Rel were equally unable to promote P19 cell differentiation. Our results demonstrate that transcriptional activation by Rel proteins correlates with Rel-induced differentiation of EC cells, and raise the intriguing possibility that Rel proteins may play an important role in early developmental processes.

Abstract
The epipodophyllotoxin derivative etoposide, an inhibitor of DNA topoisomerase II, has been found to induce internucleosomal DNA fragmentation, characteristic of apoptosis. In the present study, we examined the effect of Ca2+ depletion on VP-16-induced endonucleolytic DNA cleavage in HL-60 cells. VP-16-induced internucleosomal DNA fragmentation could not be blocked by the extracellular Ca2+ chelator EGTA. However, an intracellular Ca2+ chelator BAPTA-AM, which was added after treatment with VP-16, abolished both internucleosomal DNA fragmentation and the morphologic features of apoptosis. No significant increase of intracellular Ca2+ was found after VP-16 treatment. We demonstrate for the first time that preexisting intracellular Ca2+ plays an essential role in induction of apoptosis by VP-16 in HL-60 cells.

Abstract
cDNAs representing the alpha subunit of polyomavirus enhancer binding protein 2 (PEBP2; also called PEA2) were isolated. The products of the cDNAs are highly homologous to that of Drosophila segmentation gene runt (run) for an N-proximal 128-amino acid region showing 66% identity. The run homology region encompasses the domain capable of binding to a specific nucleotide sequence motif and of dimerizing with the companion beta subunit. The human AML1 gene related to t(8;21) acute myeloid leukemia also had a run homology region. Together with the beta subunit, which increases the affinity of the alpha subunit to DNA without binding to DNA by itself, PEBP2 represents a newly discovered family of transcription factor. The major species of PEBP2 alpha mRNA was expressed in T-cell lines but not in B-cell lines tested. Evidence indicated that PEBP2 functions as a transcriptional activator and is involved in regulation of T-cell-specific gene expression.

Abstract
Polyomavirus enhancer binding protein, PEBP2 (PEA2), is a heterodimer of two distinct subunits, alpha and beta, of which the former directly binds to DNA and the latter acts auxiliary to enhance the DNA binding. Recent cloning studies has revealed that the alpha subunit is homologous to the products of the Drosophila segmentation gene runt and the human AML1 gene, and that it functions as a major regulator for the T cell-specific gene expression. We have currently cloned cDNAs for the beta subunit. The isolated cDNAs contain three isoforms that are presumed to arise from alternative RNA splicing and encode polypeptides consisting of 187, 182, and 155 amino acids, respectively. These polypeptides neither show any significant homology with known other proteins including the alpha subunit nor have any known DNA-binding and dimerization domains. Thus, PEBP2, as the complex of these subunits, is thought to constitute an entirely novel category of heteromeric transcriptional regulator together with the Runt and AML1 proteins. Gel retardation assays of the cDNA-encoded proteins produced in an in vitro translation system or in Escherichia coli demonstrated that the larger two beta isoforms, but not the smallest one, can dimerize with the alpha subunit. Furthermore, this heterodimerization was shown to cause a marked increase in the intrinsic DNA binding affinity of the alpha subunit.

Abstract
We examined the expression of tumor-suppressor protein p53 in a variety of laryngeal carcinomas from 43 patients (25 primary, 13 metastatic and 5 recurrent cases), 13 normal laryngeal tissues and 7 benign laryngeal nodule biopsy specimens, using the polyclonal antibody CM-1. Previously we have reported a high incidence of ras mutations (51%) and human papillomavirus (HPV) infection (37%) in these laryngeal carcinomas. p53 protein was detected by immunohistochemistry in 65% of laryngeal carcinomas (60% of primary, 69% of metastatic and 80% of recurrent cases). No correlation was found between p53 over-expression and histological grading of the tumors. None of the specimens from normal larynx and laryngeal nodules revealed any detectable level of this protein. Furthermore, 11 (69%) of 16 HPV-positive cases and 17 (77%) of 22 cases with ras mutation showed variable grades of p53 expression. Twelve (71%) of 17 laryngeal carcinomas in current study having both p53 over-expression and ras mutation were moderately or poorly differentiated. Likewise, positivity for these 2 parameters was significantly increased in metastatic tumors (9 of 13 cases, 69%) as compared with primary and recurrent tumors (8 of 30 cases, 27%) (p < 0.01). Our results suggest that multiple factors are involved in this malignancy, and that the simultaneous over-expression of p53 and the presence of ras mutation may be related to the progression stage of laryngeal carcinoma.

Abstract
Breakpoints of the t(8;21) chromosome translocation in acute myeloid leukemia are clustered within the human gene, AML1, located on chromosome 21 [Miyoshi, H., Shimizu, K., Maseki, N., Kaneko, Y. & Ohki, M. (1991). Proc. Natl. Acad. Sci. USA, 88, 10431-10434]. The product of AML1 has a region about 130 amino acids long that is highly homologous to the Drosophila segmentation gene runt (runt homology region). The cDNA isolated from mouse fibroblasts encoding the alpha-subunit of polyomavirus enhancer binding protein 2 (PEBP2/PEA2) revealed that it also has a runt homology region (E. Ogawa et al., submitted). In this study, a different cDNA clone presumed to represent the mouse homolog of human AML1 (PEBP2 alpha B) was isolated from a cDNA library derived from B cells. The deduced amino acid sequence of PEBP2 alpha B is 99% identical to that of AML1 for the first 241 residues, including the runt homology region, though their sequences diverge thereafter. On the other hand, PEBP2 alpha B and PEBP2 alpha share only 92% and 82% homologies at the amino acid and nucleotide levels respectively, even for the runt homology region, indicating that these proteins are encoded by distinct genes. While PEBP2 alpha is highly expressed in T-cell lines but not in most of the B-cell lines and functions as an activator of T-cell-specific genes, PEBP2 alpha B is expressed in both types of cells. A possible functional relationship between PEBP2 alpha and PEBP2 alpha B is discussed in relation to leukemogenic potential of AML1.

Abstract
To evaluate the role of ras activation and human papillomavirus (HPV) infection in laryngeal carcinoma, we analyzed tumor DNA from 43 cases, including 25 primary laryngeal tumors, 12 lymph-node and one skin metastases, and 5 recurrent laryngeal carcinomas. Thirteen normal laryngeal tissues and 7 benign laryngeal nodule biopsy specimens along with normal tissue surrounding laryngeal carcinoma in 2 cases were also included. The polymerase-chain-reaction technique was used to amplify DNA fragments containing codon 12 and 61 of H-, K- and N-ras, also HPV 16, 18 and 33 DNA, subsequently hybridized with sequence-specific oligonucleotides. DNA samples from 22 patients with laryngeal carcinoma revealed ras mutations (18 in N-ras codon 12, 6 in H-ras codon 61, and 3 in K-ras codon 61). Likewise, HPV DNA was found in 16 cases (HPV 16, 18 and 33 in 3 cases, 14 cases and 1 case respectively). ras mutations were significantly higher in metastatic tumors (10 of 13 cases) than in primary (11 of 25 cases) and recurrent laryngeal carcinomas (1 of 5 cases). HPV DNA was detected in 60% of recurrent, 44% of primary and 15% of metastatic tumors. Only 2 of the 13 normal laryngeal tissues and 1 out of 7 laryngeal nodule specimens were found to contain HPV DNA. These results suggest that ras activation, especially in N-ras codon 12.1 (GGT-->AGT) and HPV infection are 2 important factors in (multistage) laryngeal carcinogenesis. The ras mutation may be associated with metastatic ability of the tumor.

Abstract
The frequency of H-ras, K-ras, and N-ras mutations and the presence of high-risk human papillomavirus (HPV 16, 18, and 33) DNA were studied in 75 paraffin-embedded specimens obtained from 68 Japanese patients with a variety of prostate carcinomas by using polymerase chain reaction and DNA hybridization with sequence-specific oligonucleotides. Ten specimens each of normal and benign hyperplastic prostatic tissues from the same number of patients were also examined for this analysis. Of 68 carcinoma cases, ras gene mutations were present in 16 cases (24%) and HPV DNAs in 28 cases (41%). Eleven mutations were detected in codon 61 of H-ras, 4 in codon 12 of N-ras, and 2 in codon 61 of K-ras. HPV 16, 18, and 33 DNAs were found in 11, 17, and 5 cases, respectively. Eight of the 16 cases with ras mutation also harbored HPV DNAs. The frequency of ras mutations and the HPV infection increased in patients with advanced stages of the tumor and with the higher Gleason score. There was the predominant presence of H-ras codon 61.2 (CAG-->CTG) mutation and HPV 18 DNA in prostatic carcinomas metastasizing to the bone. None of the normal or benign hyperplastic prostatic specimens contained either ras mutation or HPV DNA. Our results suggest that ras gene mutations and HPV infections are relatively frequent, at least in prostate carcinoma of Japanese patients. These two factors appear to be related to the progression of the tumor. Moreover, H-ras codon 61.2 mutation and HPV 18 infection may have some predictive roles for bone metastasis in prostate carcinoma.

Abstract
BACKGROUND AND METHODS The prevalence of type 6, 11, 16, 18, and 33 human papillomavirus (HPV) was investigated with the polymerase chain reaction (PCR) on formalin-fixed, paraffin wax-embedded material, including 48 neoplastic and 21 normal urinary bladder specimens. The PCR-amplified DNA were analyzed by gel electrophoresis and dot blot and Southern blot hybridization. Some tissues were tested further by nonisotopic in situ hybridization. RESULTS HPV DNA was detected in 39 (81%) of 48 carcinomas and 7 (33%) of 21 normal urinary bladder specimens. The presence of high-risk HPV (types 16, 18, and 33) was increased significantly in carcinoma cases (62%) as compared with normal specimens (14%) (P less than 0.01). Similarly, multiple HPV infections were significantly higher in carcinoma (60%) than in the normal tissues (5%) (P less than 0.01). The overall and high-risk HPV infections in both neoplastic and normal specimens were distributed almost equally in male and female patients. There was no significant correlation between positive results for HPV and histologic grades of the carcinoma. CONCLUSIONS These results demonstrate that the urinary bladder in both sexes is another site where infection with the common genital tract HPV may carry a risk of malignant transformation.
