Abstract
Hepatocellular carcinoma (HCC) is often associated with an inflammatory setting. A plethora of cytokines are secreted in this milieu, actively contributing to the progression of the disease; however, the extent of cytokine interaction and how it contributes to HCC development remains an enigma. In this regard, our analysis of available patient-derived data suggests that cytokines like interleukin-6 (IL-6) and transforming growth factor-beta (TGF-β) are enriched in HCC. We further analyzed the effect of these cytokines independently or in combination on HCC cells. Importantly, IL-6 was found to induce a STAT-3-dependent proliferation and mediate its pro-proliferative effects through activation and direct interaction with the p65 subunit of NFkB. Alternatively, TGF-β was found to induce a SMAD-dependent induction of epithelial to mesenchymal transition (EMT) coupled to growth arrest in these cells. Interestingly, the simultaneous addition of IL-6 and TGF-β failed to profoundly impact EMT markers but resulted in attenuation of IL-6-induced pro-proliferative effects. Analysis of the putative molecular mechanism revealed a decrease in IL-6 receptor (IL-6R) transcript levels, reduced expression of IL-6-induced STAT-3, and its nuclear localization upon addition of TGF-β along with IL-6. Consequently, a reduced p65 activation was also observed in combination treatment. Importantly, SMAD levels were unperturbed and the cells showed more TGF-β-like features under combination treatment. Finally, we observed that TGF-β resulted in enrichment of repressive chromatin mark (H3K27me3) coupled to growth arrest, while IL-6 induced an open chromatin signature (H3K4me3) associated with an enhanced expression of EZH2. Overall, for the first time, we show that TGF-β attenuates IL-6-induced effects by regulating the receptor level, downstream signaling, and the epigenome. Understanding the complex interactions between these cytokines can be imperative to a better understanding of the disease, and manipulation of cytokine balance can act as a prospective future therapeutic strategy.

Transgenic expression of tgfb1a induces hepatic inflammation, fibrosis and metastasis in zebrafish. Biochem Biophys Res Commun 2018; 509:175-181.

Abstract
TGFB signaling pathway plays a key role on liver disease progression. In our previous study, we have demonstrated the oncogenic ability of Tgfb signaling pathway as a chronic induction of tgfb1a specifically in hepatocytes led to both hepatocellular carcinoma (HCC) and cholangiocarcinoma in zebrafish. Here we would like to examine the potential mechanisms of Tgfb1a induced tumorigenesis. As majority of HCC developed from the background of liver inflammation and fibrosis, by immune-fluorescent staining on markers of liver inflammation, we indeed observed a progressively increased liver inflammation during tumorigenesis. Examination of liver fibrosis also revealed marked increase of liver fibrosis during early liver tumorigenesis and it was dramatically dropped in late liver tumorigenesis. Hence, induction of tgfb1a drives HCC through association of liver inflammation and fibrosis. Furthermore, we found high expression of EMT markers in late liver tumorigenesis, indicating a tumor metastasis potential. These observations are generally consistent with the molecular mechanisms of hepatocarcinogenesis in human.

Abstract
The concept of the immunological surveillance against neoplastic cells was initially proposed by Erlich in 1909 and later elaborated by Burnet. This hypothesis states that the normal function of the immune system, in particular the cell-mediated immunity, is to recognize and destroy the transformed and proliferating tumor cells. The role of cell-mediated immunity during the first steps of tumorigenesis remains controversial. However, there is certain evidence about its importance in the progression and dissemination of cancer. The frequent immunosuppressed condition of cancer patients at tumor relapse or recurrence of secondary tumors is a clinical sign supporting this hypothesis, and many studies have demonstrated a defective immune response in patients diagnosed with advanced cancer. Several mechanisms of escape from the immune surveillance have been described, including the immunoselection of tumor antigen-negative variants, the downregulation of MHC class I expression, suppressive T cells, and the elaboration of immunosuppressive cytokines and other factors. Because of the technical difficulty of isolating the very small amounts from culture supernatants or body fluids, only a few of these substances have been characterized and studied with respect to their biological activity: transforming growth factor-β (TGF-β), the protein p15E, interleukin 10 (IL-10), prostaglandin E2 (PGE2), mucins, suppressive E-receptor (SER), immunosuppressive acidic protein (IAP), and adhesion molecules. The possibility of monitoring cancer patients by testing biochemical factors related to cancer growth led to a proposal to measure a number of these factors as tumor markers. Some of them, e.g mucins, enjoy the consensus of the oncologic community, as for some indications they can help the clinician in the management of cancer patients. Except for the class of mucins, the other above-mentioned immunosuppressive factors have not found any clinical application in the laboratory routine because the information deriving from their measurement, although of speculative and scientific interest, has limited clinical value at present. Nevertheless, even if they have no impact on patient management, these substances do have a potential role to play in the study of cancer patients, and should be taken into account when developing new therapeutic strategies.

Abstract
Fascin plays a role in tumor metastasis under the influence of TGF-β, each potentiating the effect of the other. We retrospectively investigated whether there was a prognostic relationship between TGF-β and fascin, and disease stage, local recurrence, metastasis tendency, and response to treatment. Twelve neuroblastomas, 17 osteosarcomas, 14 Ewing's sarcomas, 15 rhabdomyosarcoma cases, and 8 rare solid tumors were included. Serum TGF-β levels were high at the time of diagnosis in all groups (p = .015) and decreased significantly during remission (p = .008). Serum TGF-β values in the relapse period rarely reached high levels at the time of diagnosis and even stayed under the control group values (p = .017). When TGF-β receptor expression in tumor tissues was evaluated, the association of TGF-β receptor positivity with metastatic disease and advanced stage was striking. We found that 88% of rhabdomyosarcoma cases with alveolar histopathology expressed the TGF-β receptor, and the association between TGF-β receptor positivity and alveolar histopathology seemed to be a negative prognostic marker. When fascin levels were evaluated in childhood solid tumor tissue, the risk of relapse increased when the fascin total score at diagnosis was >4. This is one of the few studies including prognostic markers such as serum TGF-β, tissue TGF-β, TGF-β receptor, and fascin in pediatric solid tumors. Considering the poor prognosis of advanced stage pediatric solid tumors and the need for biomarkers to predict which patient might need more intensive therapy or warrant closer follow-up afterward, we think that TGF-β, TGF-β receptor, and fascin expression have an important prognostic role.

Abstract
Systemic abrogation of TGF-β signaling results in tumor reduction through cytotoxic T lymphocytes activity in a mouse model. The administration of polysaccharide-Kureha (PSK) into tumor-bearing mice also showed tumor regression with reduced TGF-β. However, there have been no studies regarding the PSK administration to cancer patients and the association with plasma TGF-β. PSK (3 g/day) was administered as a neoadjuvant therapy for 2 weeks before surgery. In total, 31 advanced gastric cancer (AGC) patients were randomly assigned to group A (no neoadjuvant PSK; n=14) or B (neoadjuvant PSK therapy; n=17). Plasma TGF-β was measured pre- and postoperatively. The allocation factors were clinical stage (cStage) and gender. Plasma TGF-β ranged from 1.85-43.5 ng/ml (average, 9.50 ng/ml) in AGC, and 12 patients (38.7%) had a high value, >7.0 ng/ml. These patients were largely composed of poorly-differentiated adenocarcinoma with pathological stage III/IV. All the six elevated cases in group B showed a significant reduction of plasma TGF-β (from 21.6 to 4.5 ng/ml, on average), whereas this was not exhibited in group A. The cases within the normal limits of TGF-β remained unchanged irrespective of PSK treatment. Analysis of variance showed a statistically significant reduction in the difference of plasma TGF-β between groups A and B (P=0.019). PSK reduced the plasma TGF-β in AGC patients when the levels were initially high. The clinical advantage of PSK may, however, be restricted to specific histological types of AGC. Perioperative suppression of TGF-β by PSK may antagonize cancer immune evasion and improve patient prognosis in cases of AGC.

Abstract
AIM Epithelial-mesenchymal transition (EMT) is a crucial process during cancer invasion and metastasis, which is accompanied by the suppressed expression of E-cadherin initiated by stimuli such as transforming growth factor (TGF)-β. Recent studies have shown that the epigenetic regulation of E-cadherin could be an alternate mechanism of EMT induction in hepatocellular carcinoma (HCC). miRNA-29a (miR-29a) is involved in the epigenetic regulation of genes by targeting DNA methyltransferases (DNMT), which methylate CpG islands to suppress the transcription of genes. We studied the involvement of miR-29a in TGF-β-induced EMT in HCC cells. METHODS We treated human HCC cell lines with TGF-β to induce EMT. To investigate DNA methylation in EMT, cells were treated with a methylation inhibitor, 5-Aza-2'-deoxycytidine (5-Aza) and methylation status of CpG islands in the E-cadherin promoter was examined using methylation-specific PCR. Precursor miR-29a (pre-miR-29a) was electroporated to force the expression of miR-29a in HCC cells in order to study the role of miR-29a in EMT. RESULTS TGF-β transformed HCC cells into a spindle-shaped morphology accompanied by a decrease of E-cadherin with the induction of methylation of its promoter. Pretreatment of the cells with 5-Aza blocked this suppression of E-cadherin, indicating the involvement of DNA methylation. TGF-β increased DNMT3B and DNMT1 and decreased miR-29a expression. The forced expression of miR-29a abrogated the suppression of E-cadherin induced by TGF-β. CONCLUSION miR-29a could regulate TGF-β-induced EMT by affecting DNA methylation via the suppression of DNMT. These observations reveal the epigenetic regulation of genes by miRNA as a unique mechanism of EMT in HCC.

Abstract
The epithelial-mesenchymal transition (EMT) has been implicated in various pathophysiological processes, including cancer cell migration and distal metastasis. Reactive oxygen species (ROS) and insulin receptor substrate-1 (IRS-1) are important in cancer progression and regulation of EMT. To explore the biological significance and regulatory mechanism of EMT, we determined the expression, the biological function and the signaling pathway of prostate transmembrane protein, androgen induced-1 (TMEPAI), during the induction of EMT and cell migration. Transforming growth factor (TGF)-β1 significantly upregulated the expression of TMEPAI during EMT in human lung adenocarcinoma. Depletion of TMEPAI abolished TGF-β1-induced downregulation of ferritin heavy chain and the subsequent generation of ROS, thus suppressing TGF-β1-induced EMT and cell migration. In addition, increased ROS production and overexpression of TMEPAI downregulated the level of IRS-1. Both the addition of H2O2 and IRS-1 small interfering RNA rescued the ability of TGF-β1 to induce EMT in TMEPAI-depleted cells. Remarkably, the levels of TMEPAI in lung tumor tissues are very high, whereas its expression in normal lung epithelium is very low. Moreover, TMEPAI expression was positively correlated with the cell mesenchymal phenotype and migration potential. Our work reveals that TMEPAI contributes to TGF-β1-induced EMT through ROS production and IRS-1 downregulation in lung cancer cells.

Abstract
Pathological deregulation of the transforming growth factor, beta 1 (TGFB1) pathway has been implicated in the development of several major diseases, including cancers. Regulatory variation in the TGFB1 gene may lead to altered TGFB1 expression and activity, and thus, modulate an individual's susceptibility to disease. Here, we performed a study of the functional relevance of cis-acting regulatory variation in the proximal promoter region of the TGFB1 gene. In a previous study, 9 promoter polymorphisms were identified in the 2kb region upstream of the transcription start site and 9 distinct promoter haplotypes were inferred from a panel of individuals from 5 distinct continental population groups. Following experimental validation, we found that the 2 major haplotypes significantly influenced TGFB1 transcriptional activity in an allele-specific manner and that 3 of the SNPs (-1886G>A, -509C>T and -1550DEL/AGG) altered DNA-protein complex formation. Though the biological relevance of these findings remains to be verified, our study suggests that polymorphisms in the TGFB1 promoter could indeed influence gene expression and potentially contribute to the pathogenesis of TGFB1 related diseases.

Abstract
The proliferation of colorectal epithelial cells is regulated by various stimuli including cytokines and growth factors, thus the variants of those genes can modify the colorectal cancer risk. TGF-[beta]1 can act as both a tumor suppressor and a stimulator of tumor progression. TGF-[beta]1 C-509T polymorphism in the promoter sequence has been associated with increased levels of plasma TGF-[beta]1 in individuals with T allele. To evaluate the potential influences of this polymorphism on colorectal adenoma and cancer risk, a case-control study was conducted in Korea. A total of 646 subjects were prospectively enrolled in Seoul National University Hospital. Risk of colorectal neoplasms was evaluated separately for 244 patients with colorectal adenoma, 152 patients with colorectal cancer relative to 250 healthy controls. Genotypes were determined by the PCR-RFLP method. ORs and 95% CIs were calculated by a multivariate logistic regression analysis. The TGF-[beta]1 -509T allele containing genotypes posed a reduced risk of colorectal cancer (adjusted OR = 0.59, 95% CI = 0.28-0.92). But there was no association between this polymorphism and colorectal adenoma. Our results suggest that the TGF-[beta]1 -509T allele may have a protective role in the development of colorectal cancer, possibly consistent with its role as an inhibitor of epithelial malignant transformation.

Abstract
There is a significant phenotypic variance among cystic fibrosis (CF) patients. Due to the role of TGF-beta1 in fibrotic processes we investigated its role in CF pathogenesis. TGF-beta 1 codons 10 and 25 were genotyped in 118 Czech CF patients and 268 controls by PCR-ARMS. Difference between CF and controls was found at codon 10, lower frequency of T/T homozygotes, and codon 25, higher frequency of G/C heterozygotes. We did not prove the association of TGF-beta1 polymorphisms and lung function in CF, however, the TT (codon 10)/GG (codon 25) genotype was preferentially associated with CF-related liver disease and diabetes. Independent of the TGF-beta1 genotype, production of cytokine was higher in patients than in controls with the notable exception of very low levels in Burkholderia cepacia complex colonized patients. In CF, both extremes, highest or lowest TGF-beta 1 production, were associated with impaired lung function.

Abstract
PURPOSE AND EXPERIMENTAL DESIGN Dendritic cells (DCs) are important for immune surveillance and play a central role in protection against infection and malignancy. DCs comprise two subsets: DC1 (myeloid DC) and DC2 (lymphoid DC). The aim of this study is to determine whether the number and/or function of circulating DCs were decreased in patients with pancreatic cancer and to evaluate the effects of these changes in patients with locally advanced pancreatic cancer before and after chemoradiotherapy (CRT). We examined the circulating DC number and function using the peripheral blood from 29 patients with pancreatic cancer and 20 healthy control subjects. In patients who underwent CRT (n = 20), blood samples were taken before and after CRT. DCs were tested for the ability to stimulate allogeneic T lymphocytes in mixed leukocyte reaction (MLR). CD4/8, NK activity, PHA, and TGF-beta1 were also measured. RESULTS The number and allostimulatory activity of circulating DC1s in patients were significantly lower than those in controls. In the patients who underwent CRT, the allostimulatory activity of DC1s at post-CRT was significantly increased as compared to those at pre-CRT. The level of TGF-beta1 was also significantly decreased at post-CRT as compared to pre-CRT. There were no changes in CD4/8, NK activity and proliferative response of T lymphocytes at the peri-CRT period. CONCLUSION These data indicate that the number and function of circulating DCs were impaired in patients with pancreatic cancer. Chemoradiotherapy, however, improved DC function, which might be related to decreased immunosuppressive cytokine levels.

Abstract
Transgenic mice that overexpress cyclin D1 protein in the liver develop liver carcinomas with high penetrance. Transforming growth factor beta (TGF-beta) serves as either an epithelial cell growth inhibitor or a tumor promoter, depending on the cellular context. We interbred LFABP-cyclin D1 and Alb-TGF-beta1 transgenic mice to produce cyclin D1/TGF-beta1 double transgenic mice and followed the development of liver tumors over time, characterizing cellular and molecular changes, tumor incidence, tumor burden, and tumor physiology noninvasively by magnetic resonance imaging. Compared with age-matched LFABP-cyclin D1 single transgenic littermates, cyclin D1/TGF-beta1 mice exhibited a significant increase in tumor incidence. Tumor multiplicity, tumor burden, and tumor heterogeneity were higher in cyclin D1/TGF-beta1 mice compared with single transgenic littermates. Characteristics of cyclin D1/TGF-beta1 livers correlated with a marked induction of the peripheral periductal oval cell/stem cell compartment of the liver. A number of cancerous lesions from cyclin D1/TGF-beta1 mice exhibited unique features such as ductal plate malformations and hemorrhagic nodules. Some lesions were contiguous with the severely diseased background liver and, in some cases, replaced the normal architecture of the entire organ. Cyclin D1/TGF-beta1 lesions, in particular, were associated with malignant features such as areas of vascular invasion by hepatocytes and heterogeneous hyperintensity of signal on T2-weighted magnetic resonance imaging. These findings demonstrate that TGF-beta1 promotes stem cell activation and tumor progression in the context of cyclin D1 overexpression in the liver.

Abstract
We examined the association between an elevated plasma TGF-beta 1 level and the disease progression of advanced breast cancer (BC) patients (n = 44). TGF-beta 1 levels were detected by an enzyme-linked immunosorbent assay (ELISA). Platelet carryover and in vitro platelet activation in our plasma samples was assessed and found to be insignificant. Plasma TGF-beta 1 values were significantly elevated (P < 0.05) in stage IIIB/IV patients (median value: 2.40 ng/ml, range: 0.13-8.48 ng/ml, n = 44) compared with healthy donors (median value: 1.30 ng/ml, range: 0.41-4.93 ng/ml, n = 36). Although pronounced in metastatic patients, especially those who had been newly diagnosed, TGF-beta 1 elevation was independent of tumour mass, site of distant metastases, histopathological type, steroid receptor (SR) content and age of the BC patients. Follow-up of 6 patients indicated a relationship between the plasma TGF-beta 1 and the patient's response. This suggests that TGF-beta 1, may be a promising prognostic marker for breast cancer patients with advanced disease. Confirmatory large-scale studies are needed, particularly given the overlap of values between our different subgroups analysed.

Abstract
Transforming growth factor (TGF)-beta1 is the most abundant growth factor in human bone. It is produced by osteoblasts and inhibits osteoclast proliferation and activity and stimulates proliferation and differentiation of preosteoblasts. Several polymorphisms have been described in the TGF-beta1 gene. Previously, we and others have found associations between some of these polymorphisms and bone mass. We therefore wanted to examine if these polymorphisms are also predictors of osteoporotic fractures. The polymorphisms G(-1639)-A, C(-1348)-T, C(-765)insC, T(29)-C, G(74)-C, 713-8delC, C(788)-T, and T(816-20)-C were examined using RFLP and sequencing in 296 osteoporotic patients with vertebral fractures and 330 normal individuals. Bone mineral density (BMD) was examined at the lumbar spine and at the femoral neck by DXA. Genotype distributions were in H-W equilibrium. Linkage disequilibrium was found between the polymorphisms. The T(816-20)-C genotypes were distributed differently among osteoporotic patients and normal controls. The TT genotype was less common in individuals with osteoporotic fractures (chi(2) = 6.02, P < 0.05). BMD was higher in individuals with the TT-genotype (T(816-20)-C) at the lumbar spine, 0.960 +/- 0.173 g/cm(2) compared with individuals with the TC or CC genotypes: 0.849 +/- 0.181 g/cm(2) and 0.876 +/- 0.179 g/cm(2), respectively (P < 0.001, ANOVA). Similar differences between genotypes were found at the different hip regions as well as at the total hip. Individuals with the TT-genotype (C(-1348)-T) had higher bone mass at the femoral neck: 0.743 +/- 0.134 g/cm(2) compared with 0.703 +/- 0.119 g/cm(2) in individuals with TC or CC genotypes (P < 0.05). Individuals with the CC-genotype (T(29)-C) had higher bone mass at the femoral neck, 0.735 +/- 0.128 g/cm(2) compared with 0.703 +/- 0.120 g/cm(2) in individuals with TC or TT genotypes (P < 0.05) and at the total hip: 0.852 +/- 0.166 g/cm(2) vs. 0.818 +/- 0.149 g/cm(2), respectively (P < 0.05). None of the other polymorphisms were distributed differently in patients and controls and did not affect BMD. In conclusion, The TT genotype of the T(816-20)-C polymorphism is less common in patients with osteoporotic fractures and is associated with higher bone mass both at the lumbar spine and at the hip. The C(-1348)-T and T(29)-C polymorphisms were distributed similarly in osteoporotic patients and normal controls, however, the rare genotypes were associated with higher bone mass at the hip.

Abstract
BACKGROUND Allogeneic blood stem-cell donors demonstrate more vigorous mobilization of CD34(+) cells to the circulation in response to cytokine administration than do autologous donors. Transforming growth factor (TGF-beta1) has been implicated as a mobilization inhibitor. A study was designed to determine whether plasma TGF-beta1 levels are elevated in cytokine-mobilized autologous cancer donors compared with cytokine-mobilized normal donors. METHODS Plasma collected from 29 autologous cancer donors and 33 normal allogeneic stem-cell donors following administration of mobilizing cytokines just prior to the first collection was assayed for TGF-beta1 using a sandwich-type ELISA. Plasma from three volunteers not treated with cytokine was also analyzed. Comparisons were made using the Student's t test on log-transformed data. RESULTS Average TGF-beta1 levels in the plasma of cancer patients were significantly higher than in allogeneic stem-cell donors (4.4 ng/mL versus 7.2 ng/mL; p = 0.038). The allogeneic donors required fewer collections to harvest greater numbers of CD34(+) cells and colony-forming unit granulocyte-macrophage (CFU-GM) than autologous donors. Plasma from three untreated volunteers had mean TGF-beta1 levels of 0.36 ng/mL, with all three levels below the 25th percentile for allogeneic donors and the 5th percentile for cancer patients. DISCUSSION Cytokine administration was associated with increased plasma TGF-beta1 levels. The levels were higher in cancer patients being mobilized for stem-cell collection than in allogeneic blood stem-cell donors. These differences could underlie the increased number of apheresis procedures required to harvest autologous graft products from cancer patients.

Abstract
BACKGROUND The objective of the present study was to elucidate possible relationships between four polymorphisms of the TGF-beta1 gene (-800G>A; -509C>T; Leu10Pro; Arg25Pro) and stage, histological activity grade and progression rate of liver fibrosis, classified according to the METAVIR-score. METHODS Three study groups, i.e. 48 patients with hepatic fibrosis (26 with known duration of hepatitis C virus infection), 47 patients with non-fibrotic diseases and 50 healthy blood donors, were analyzed for TGF-beta1 polymorphisms using ARMS-PCR and sequence analysis. The concentrations of total TGF-beta1 in plasma and of hyaluronan, P-III-NP and activities of transminases in serum were measured. RESULTS The presence of proline at codons 10 and/or 25 was associated with a faster progression of fibrosis than other polymorphisms. Patients with the genotype (25)ArgPro developed fibrosis significantly faster (0.23 units/year) than those having (25)ArgArg (0.08 units/year). Similarly, the fibrosis progression rate of patients with genotypes (10)LeuPro and (10)ProPro was almost three times as fast as of those having genotype (10)LeuLeu. Stage and histological activity grade of fibrosis in (25)ArgPro in comparison to (25)ArgArg were higher. Also (10)LeuPro showed a higher average stage of fibrosis than (10)LeuLeu. The TGF-beta1 plasma concentrations of patients with hepatic fibrosis were not significantly different between carriers of (25)ArgArg and (25)ArgPro genotypes. The frequency of the genotype (25)ArgPro in liver fibrotic patients was about three times that of the control group whereas the frequency distribution of the genotype (25)ArgArg tended to lower frequency in the fibrosis group. TGF-beta1-promoter polymorphisms did not show any correlation with stage, grade or progression of liver fibrosis. CONCLUSION Our results indicate that the heterozygous ArgPro of codon 25 predicts significantly faster fibrotic progression of chronic hepatitis C than the homozygous (25)ArgArg genotype. The homozygous LeuLeu genotype of codon 10 showed a slow progression of fibrosis.

Abstract
PURPOSE The ability to prescribe treatment based on relative risks for normal tissue injury has important implications for oncologists. In non-small-cell lung cancer, increasing the dose of radiation may improve local control and survival. Changes in plasma transforming growth factor beta (TGFbeta) levels during radiotherapy (RT) may identify patients at low risk for complications in whom higher doses of radiation could be safely delivered. PATIENT AND METHODS Patients with locally advanced or medically inoperable non-small-cell lung cancer received three-dimensional conformal RT to the primary tumor and radiographically involved nodes to a dose of 73.6 Gy (1.6 Gy twice daily). If the plasma TGFbeta level was normal after 73.6 Gy, additional twice daily RT was delivered to successively higher total doses. The maximum-tolerated dose was defined as the highest radiation dose at which < or = one grade 4 (life-threatening) late toxicity and < or = two grade 3 to 4 (severe life-threatening) late toxicities occurred. RESULTS Thirty-eight patients were enrolled. Median follow-up was 16 months. Twenty-four patients were not eligible for radiation dose escalation beyond 73.6 Gy because of persistently abnormal TGFbeta levels. Fourteen patients whose TGFbeta levels were normal after 73.6 Gy were escalated to 80 Gy (n = 8) and 86.4 Gy (n = 6). In the 86.4-Gy group, dose-limiting toxicity was reached because there were two (33%) grade 3 late toxicities. CONCLUSION It is feasible to use plasma TGFbeta levels to select patients for RT dose escalation for non-small-cell lung cancer. The maximum-tolerated dose using this approach is 86.4 Gy.

Abstract
OBJECTIVES To assess expression of the immunosuppressive cytokines IL-10 and TGF-beta in the ascitic fluid and plasma of advanced ovarian cancer patients. DESIGN A prospective study. SETTING The Department of Obstetrics and Gynaecology at the University of Arkansas for Medical Sciences. POPULATION Twenty-eight women diagnosed with advanced ovarian cancer and ten normal female controls. METHODS Plasma and ascitic samples were collected at the time of surgery and analysed for the presence of IL-10 and TGF-beta using a sensitive enzyme-linked immunosorbent assay. RESULTS Elevated levels of IL-10 were detected in the plasma [mean (SD) = 12 (5) pg/mL; range 8 to 23 pg/mL] and in the peritoneal fluid [mean (SD) = 165 (137) pg/mL; range 50 to 556 pg/mL] of ovarian cancer patients, while no detectable IL-10 was found in any of the normal control plasma samples tested. Similarly, plasma levels of TGF-beta in ovarian cancer patients were significantly higher [mean (SD) = 1,506 (246) pg/mL; range 1,020 to 2,070 pg/mL] compared with controls [mean (SD) = 937 (187) pg/mL; range 770 to 1,140 pg/mL](P < 0.001). Surprisingly, however, although elevated TGF-beta levels were also detected in the peritoneal fluid of all ovarian cancer patients [mean (SD) = 407 (158) pg/mL; range 140 to 770 pg/mL], these levels were significantly lower than those seen in matched plasma samples (P < 0.001). CONCLUSIONS Local and systemic secretion of immunosuppressive cytokines may play an important role in the impaired anti-tumour immune function commonly observed in advanced ovarian cancer. However, the observation that plasma levels of TGF-beta are significantly higher than those detected in the ascitic fluid raises the possibility that cells other than tumour cells are responsible for TGF-beta release in the bloodstream of these patients.

Abstract
PURPOSE To correlate the volume of lung irradiated with changes in plasma levels of the fibrogenic cytokine transforming growth factor beta (TGFbeta) during radiotherapy (RT), such that this information might be used to predict the development of symptomatic radiation-induced lung injury (SRILI). METHODS AND MATERIALS The records of all patients with lung cancer treated with RT with curative intent from 1991 to 1997 on a series of prospective normal tissue injury studies were reviewed. A total of 103 patients were identified who met the following inclusion criteria: (1) newly diagnosed lung cancer of any histology treated with RT +/- chemotherapy with curative intent; (2) no evidence of distant metastases or malignant pleural effusion; (3) no thoracic surgery after lung RT; (4) no endobronchial brachytherapy; (5) follow-up time more than 6 months; (6) plasma TGFbeta1 measurements obtained before and at the end of RT. The concentration of plasma TGFbeta1 was measured by an enzyme-linked immunosorbent assay. Seventy-eight of the 103 patients were treated with computed tomography based 3-dimensional planning and had dose-volume histogram data available. The endpoint of the study was the development of SRILI (modified NCI [National Cancer Institute] common toxicity criteria). RESULTS The 1-year and 2-year actuarial incidence of SRILI for all 103 patients was 17% and 21%, respectively. In those patients whose TGFbeta level at the end of RT was higher than the pre-RT baseline, SRILI occurred more frequently (2-year incidence = 39%) than in patients whose TGFbeta1 level at the end of RT was less than the baseline value (2-year incidence = 11%, p = 0.007). On multivariate analysis, a persistent elevation of plasma TGFbeta1 above the baseline concentration at the end of RT was an independent risk factor for the occurrence of SRILI (p = 0.004). The subgroup of 78 patients treated with 3-dimensional conformal radiotherapy, who consequently had dose-volume histogram data, were divided into groups according to their TGFbeta1 kinetics and whether their V(30) level was above or below the median of 30%. Group I (n = 29), with both a TGFbeta1 level at the end of RT that was below the pre-RT baseline and V(30) < 30%; Group II (n = 35), with a TGFbeta1 level at the end of irradiation that was below the baseline but a V(30) > or = 30% or with a TGFbeta1 level at the end of RT that was above the pre-RT baseline but V(30) < 30%; Group III (n = 14), with both a TGFbeta1 level at the end of RT that was above the baseline and V(30) > or = 30%. A significant difference was found in the incidence of SRILI among these three groups (6.9%, 22.8%, 42.9%, respectively, p = 0.02). CONCLUSIONS (1) An elevated plasma TGFbeta1 level at the end of RT is an independent risk factor for SRILI; (2) The combination of plasma TGFbeta1 level and V(30) appears to facilitate stratification of patients into low, intermediate, and high risk groups. Thus, combining both physical and biologic risk factors may allow for better identification of patients at risk for the development of symptomatic radiation-induced lung injury.

Abstract
PURPOSE To investigate the relationship between loss of heterozygosity (LOH) at the mannose 6-phosphate/insulin-like growth factor 2 receptor (M6P/IGF2R) gene locus and the development of radiation-induced lung injury. MATERIAL AND METHODS Thirty-five lung cancer patients with both stored plasma for Transforming Growth Factor beta1 (TGFbeta1) analysis and sufficient quantities of archival pathology tissue to screen for LOH were studied. All patients had been treated with thoracic radiotherapy for their malignancy and had radiographically detectable tumor present before beginning radiotherapy. Tumor and normal cells were microdissected from archival lung cancer pathology specimens. Two polymorphisms in the 3' untranslated region of the M6P/IGF2R were used to screen for LOH. Plasma TGFbeta1 levels were measured using acid-ethanol extraction and an ELISA. TGFbeta1 and M6P/IGF2R protein expression was estimated by immunofluorescence and immunohistochemical staining. Symptomatic radiation pneumonitis was scored according to National Cancer Institute Common Toxicity Criteria without knowledge of the results of TGFbeta or LOH analyses. RESULTS Of the 35 patients, 10 were homozygous for this polymorphism (noninformative) and were excluded. Of the 25 informative patients, 13 had LOH. Twelve of 13 patients with LOH had increased pretreatment plasma TGFbeta1 levels, vs. 3/12 patients without LOH (p < 0.01). A decrease or loss of M6P/IGF2R protein in the malignant cell accompanied by increased latent TGFbeta1 protein in extracellular matrix and tumor stroma was found in tumors with LOH, suggesting that this mutation resulted in loss of function of the receptor. Seven of 13 (54%) LOH patients developed symptomatic radiation-induced lung injury vs. 1/12 (8%) of patients without LOH (p = 0.05). CONCLUSION Loss of the M6P/IGF2R gene strongly correlates with the development of radiation pneumonitis after thoracic radiotherapy (RT). Furthermore, patients with LOH (in the setting of measurable tumor) are much more likely to have elevated plasma TGFbeta, suggesting an inability to normally process this cytokine. Thus, loss of the M6P/IGF2R gene may predispose patients to the development of radiation-induced lung injury.

Abstract
Radiation therapy (RT) is frequently used to treat patients with tumors in and around the thorax. Clinical radiation pneumonitis is a common side effect, occurring in 5% to 20% of patients. Efforts to identify patients at risk for pneumonitis have focused on physical factors, such as dose and volume. Recently, the underlying molecular biological mechanisms behind RT-induced lung injury have come under study. Improved knowledge of the molecular events associated with RT-induced lung injury may translate into a better ability to individualized therapy. This review discusses our current understanding of the physical and molecular factors contributing to RT-induced pulmonary injury.

Abstract
In Japan, the proportion of hemophiliacs infected with human immunodeficiency virus type 1 (HIV-1) is 40%, whereas more than 90% are infected with hepatitis C virus (HCV). To evaluate the immunological status of hemophiliacs infected with HIV-1, we investigated the pattern of cytokine production in peripheral blood mononuclear cells (PBMCs) of HIV-1-seropositive and -seronegative hemophiliacs, HIV-1-seropositive non-hemophiliacs, and healthy individuals. The production of IL-18 and IL-1beta from PBMCs stimulated with Staphylococcus aureus Cowan strain 1 (SAC) in the HIV-1-seropositive hemophiliacs was significantly decreased in comparison with the other groups. On the other hand, IL-12 production in both HIV-1-seropositive groups was significantly lower than in HIV-1-seronegative groups. TNF-alpha and IL-6 production was similar among the four groups. In contrast, plasma levels of TGF-beta1 were increased in HIV-1-seropositive hemophiliacs, HIV-1-seropositive nonhemophiliacs, and HIV-1-seronegative hemophiliacs, with the highest levels being in HIV-1-seropositive hemophiliacs, suggesting that coinfection with HIV-1 and HCV increases the level of plasma TGF-beta in HIV-1-seropositive hemophiliacs. Treatment of PBMCs from healthy individuals with TGF-beta1 inhibited IL-18 and IL-1beta production without affecting IL-6, IL-10, or TNF-alpha production. Suppression of the expression of caspase 1 mRNA, which is known to be an IL-1beta-converting enzyme and which also cleaves the precursor of IL-18, was observed in the SAC-stimulated PBMCs from healthy individuals after treatment with TGF-beta1 and in the SAC-stimulated PBMCs from HIV-1-seropositive hemophiliacs, suggesting that the decreased production of IL-18 and IL-1beta in HIV-1-seropositive hemophiliacs may be related to the downregulation of caspase 1 mRNA induced by high levels of TGF-beta1 in plasma.

Abstract
The cytokine transforming growth factor-beta (TGF-beta) was initially purified from human platelets, a rich source of this protein. In addition to platelets, TGF-beta1 is also found in other blood fractions, including plasma and the circulating leukocytes. However, more than 15 years after the initial isolation of TGF-beta1, there remains no consensus on how much TGF-beta1 is present in normal human plasma. Here we review the difficulties associated with measuring TGF-beta concentrations in complex biological fluids, and discuss the current state of knowledge on the distribution of TGF-beta isoforms in various blood fractions as well as the nature of the TGF-beta-containing protein complexes.

Abstract
Intracerebroventricular administration into sedentary mice of the high molecular mass fraction of cerebrospinal fluid (CSF) from exercise-exhausted rats produced a decrease in spontaneous motor activity [K. Inoue, H. Yamazaki, Y. Manabe, C. Fukuda, T. Fushiki, Release of a substance that suppresses spontaneous motor activity in the brain by physical exercise, Physiol. Behav. 64 (1998) 185-190]. CSF from sedentary rats had no such effect. This suggests the presence of a substance regulating the urge for motion as a response to fatigue. A bioassay system using hydra, a freshwater coelenterate, showed an activity indistinguishable from transforming growth factor-beta (TGF-beta) in the CSF from exercise-fatigued rats, while not in that from sedentary rats. The increase in the concentration of active TGF-beta in the CSF from exercise-fatigued rat was also ascertained by another bioassay system using mink lung epithelial cells (Mv1Lu). Injection of TGF-beta into the brains of sedentary mice elicited a similar decrease in spontaneous motor activity in a dose-dependent manner. Increasing the exercise load on rats raised both the levels of active TGF-beta and the activity of depression on spontaneous motor activity of mice in the CSF of rats. Taken together, these results suggest that exercise increases active TGF-beta in the brain and it creates the feeling of fatigue and thus suppresses spontaneous motor activity.

Abstract
PURPOSE The pleotropic cytokine TGF-beta1 which induces connective tissue synthesis, and inhibits the growth of smooth muscle cells, has been implicated in corpus cavernosum fibrosis. The objective of this study was to determine the dose and time dependence of TGF-beta1 as an active agent in penile corporal fibrosis in an animal model. MATERIALS AND METHODS A time release method of delivery was developed using sodium alginate microspheres containing recombinant human (rh) TGF-beta1. New Zealand White rabbits were injected intracorporally with a single alginate microsphere either with or without rh-TGF-beta1. Dosage was varied from 325 to 1500 ng./bead. Animals were sacrificed at either three or five days post injection and the penises removed en bloc, examined, and processed for quantitative histomorphometric analysis, staining the sections with Masson's trichrome. RESULTS Alginate microspheres containing [125I]-rh-TGF-beta1 showed slow-release kinetics (t1/2 = 10.5 hours). Histomorphometric analysis of 60 sets of high powered fields/treatment/ animal showed dose dependent decreases in percentage of corporal smooth muscle with TGF-beta1 treatment (750 to 1500 ng./bead). Placebo (alginate microspheres alone) had trabecular smooth muscle content comparable to values previously reported for untreated rabbit corpus cavernosum. CONCLUSIONS This study confirms that TGF-beta1 induces fibrosis in situ by altering connective tissue synthesis and hence the structure of the corpus cavernosum. Injection of rh-TGF-beta1 impregnated alginate microspheres into the corpus cavernosum resulted in dose-dependent decreases in percentage of corporal smooth muscle.

Abstract
Hepatocellular carcinoma (HCC) is a common, potentially lethal tumor in human patients. Because the serum levels of transforming growth factor-beta1 (TGF-beta1) correlate with outcome in patients with HCC and because TGFbeta1 mRNA expression is increased in HCC tissues, it raises the possibility that TGF-beta1 may be of importance in the development, growth, and metastases of HCC. Tamoxifen has been used for the treatment of human HCC. However, clinical trials have produced conflicting results. To further delineate whether tamoxifen may be of benefit in altering the course of HCC, we documented the effects of 4-hydroxytamoxifen and 17beta-estradiol on TGF-beta1 mRNA and protein levels and cell proliferation in a human HCC cell line. PLC/PRF/5 cells were treated with carrier (controls), 4-hydroxytamoxifen, 17beta-estradiol, or TGF-beta1. 4-Hydroxytamoxifen and 17beta-estradiol decreased TGF-beta1 mRNA and protein levels in a time- and dose-dependent manner. TGF-beta1 significantly inhibited PLC/PRF/5 cell proliferation, whereas both 4-hydroxytamoxifen and 17beta-estradiol stimulated PLC/PRF/5 cell proliferation. The stimulatory effects of 4-hydroxytamoxifen on PLC/PRF/5 cell proliferation raise concerns regarding its use in the treatment of HCC in human patients and suggest that 4-hydroxytamoxifen may have no beneficial effects in some patients with HCC.

Abstract
PURPOSE Specific cytokines have been found to be secreted by and influence the growth of prostate cancers in cell culture. Interleukin-6 (IL-6), tumor necrosis factor alpha (TNFalpha), granulocyte macrophage-colony stimulating factor (GM-CSF) and transforming growth factor-beta1 (TGF-beta1) have all been closely associated with prostate cancer. We analyzed the levels of these cytokines in the systemic circulation of patients with varying stages of prostate cancer compared to controls. MATERIALS AND METHODS Serum IL-6, TNFalpha and GM-CSF were measured using commercially available enzyme linked immunosorbent assays in 5 groups of patients, including controls-19 men presenting to prostate cancer screening with normal digital rectal examination and serum prostate specific antigen (PSA) no greater than 2.0 ng./ml., stage pT2-19 with cancer confined to the prostate in the radical prostatectomy specimen, stage pT3-10 with extraprostatic extension and/or seminal vesicle involvement, stage N1-12 with lymph node metastases at pelvic lymph node dissection, and stage M1-9 with bone metastases. Platelet poor plasma TGF-beta1 was measured using a commercially available enzyme linked immunosorbent assay in controls and patients with stage M1 disease only because it was not available for patients with stages pT2, pT3 and N1 disease. No patient had a history of any other malignancy. All blood specimens were collected before surgery and/or androgen ablation. Statistical analysis was done with the Kruskal-Wallis analysis of variance. RESULTS Serum IL-6 and platelet poor plasma TGF-beta1 were significantly elevated in patients with clinically evident metastases (p = 0.0008 and 0.0412, respectively) while serum GM-CSF and TNFalpha were not. IL-6 and TGF-beta1 correlated with increasing serum PSA (p = 0.0335 and 0.0386, respectively). GM-CSF did not correlate with PSA or age. In multivariate analysis TNFalpha correlated with age but not PSA. CONCLUSIONS IL-6 and TGF-beta1 correlate with tumor burden as assessed by serum PSA or clinically evident metastases. Further research is needed to determine the response to androgen ablation as well as the source(s) and actions of these cytokines.

Abstract
Transforming growth factor beta1 (TGF-beta1) has been implicated as inhibitor of cell proliferation and a potent inducer of apoptosis in vitro and in vivo after the administration of high doses. To assess the role of endogenous TGF-beta1, we quantitated the cytokine and its receptors in rat liver during regenerative and hyperplastic growth, regression by apoptosis, and in hepatocellular carcinoma (HCC). This was accomplished by Northern blot analysis and by RNase protection assay of the messenger RNA (mRNA) of TGF-beta1 and TGF-beta receptors (TbetaR) types I to III and by an activity bioassay of the TGF-beta proteins. Untreated rat livers were found to contain 15.6 +/- 4.8 ng TGF-beta1 protein/g tissue; TGF-beta2 protein was not detected. To induce toxic cell death and subsequent regenerative DNA synthesis in the liver, rats were treated with a necrogenic dose of carbon tetrachloride (CCl4). After 24 and 48 hours, there was an upregulation of TGF-beta1 (mRNA, up to tenfold; protein, about twofold) and of TbetaRs (mRNA: two- to fourfold); that indicates an overall enhanced production of and sensitivity to TGF-beta1, which may serve to confine the regenerative response. Hyperplastic liver growth and regression of the hyperplasia were induced by treatment with cyproterone acetate (CPA) or nafenopin (NAF) followed by withdrawal; neither mRNAs of TGF-beta1 and TbetaR types I to III nor TGF-beta1 protein exhibited significant changes during the growth phase or during regression by apoptosis. We also studied neoplastic growth. HCC, obtained after long-term treatment with NAF, exhibited high rates of cell replication and apoptosis. The majority of lesions contained mRNA and protein of TGF-beta1 and mRNA of TbetaR types I to III at concentrations similar to those of the surrounding tissue. In conclusion, during liver regeneration there is a pronounced upregulation of expression of both TGF-beta1 and TbetaRs I to III, but not during mitogen-induced liver growth or regression. It appears that apoptosis is induced via altered local concentration of TGF-beta1, in a paracrine and/or autocrine way. By this mechanism the lethal effects of TGF-beta1 may be locally confined, and overshoots of apoptosis in the liver may be prevented.

Abstract
Hepatocellular carcinoma (HCC) is estimated to have an annual worldwide incidence of 0.25 to 1.2 million new cases per year. Both the prevalence and incidence of HCC vary markedly as a function of geography and the local prevalence of chronic viral hepatitis. Both chronic hepatitis B and chronic hepatitis C are recognized as risk factors for HCC. The prevalence of cirrhosis in individuals with HCC and chronic hepatitis B or C is reported to be 80.9% and 75.8%, respectively. HCC occurs at a lower rate in chronic viral hepatitis in the absence of cirrhosis. Moreover, hepatitis C virus (HCV) rather than hepatitis B virus (HBV) is associated with the majority of non-cirrhotic cases of HCC. It is probable that the ongoing process of hepatocyte necrosis and liver cell renewal coupled with inflammation, which is characteristic of chronic viral hepatitis, causes not only nodular regeneration and cirrhosis but also progressive genomic errors in hepatocytes as well as unregulated growth and repair mechanisms leading to hepatocyte dysplasia and, in some cases, hepatic carcinoma. Current concepts concerning virus-induced HCC are reported and discussed in the following review.

Abstract
The protein products of oncogenes and tumor suppressor genes play critical roles in the development of many cancers. The expression of a number of these proteins can be detected in extracellular fluids such as blood. This article reviews the literature on the application of methods for the detection of the proteins of oncogenes and tumor suppressor genes in the blood of humans with cancer or at risk for the development of cancer. The detection of these proteins in blood may be useful molecular markers of carcinogenesis that could play an important part in cancer diagnosis, prognosis, and prevention.

Abstract
Changes in TGF-beta plasma levels were observed 18 weeks after hemithoracic irradiation in rats. This coincides with an increase in the breathing frequency. being most pronounced between 22 and 28 weeks after irradiation. The correlation suggests a potential role of the circulating TGF-beta in the monitoring of localized radiation-induced lung injury.

Abstract
This article reviews the literature on the application of methods for the detection of growth factors, oncogene proteins, and tumor-suppressor gene proteins in the blood of humans with cancer or who are at risk for the development of cancer. The research summarized here suggests that many of these biomarker assays can be used to distinguish between diseased and nondiseased states and in some instances may be able to predict susceptibility for future disease. Thus, these biomarkers could be valuable tools for monitoring at-risk populations for purposes of disease prevention and control.

Abstract
To assess the clinical relevance of transforming growth factor-beta 1 (TGF-beta 1) in the urine of patients with hepatocellular carcinoma (HCC), TGF-beta 1 was measured, by radioimmunoassay, in 140 patients with HCC, 50 cirrhotic patients, 30 patients with chronic active hepatitis, and 50 healthy controls. The results indicate that there were significantly increased urinary TGF-beta 1 levels in patients with HCC. Raised TGF-beta 1 levels were associated, in a dose-related fashion, with increased risk for development of HCC (odds ratio, 1.05, 95% confidence interval, 1.03-1.07). HCC patients with raised TGF-beta 1 levels had shorter survival than those with normal TGF-beta 1 levels (p = 0.038). TGF-beta 1 levels decreased after successful anticancer therapy (p < 0.0001). There was an inverse correlation between TGF-beta 1 and serum alpha-fetoprotein (AFP) (r = -0.199, p < 0.04). Receiver operating characteristics (ROC) curve analysis indicated that parallel determination of TGF-beta 1 and AFP significantly increased the sensitivity and diagnostic accuracy, with a high specificity. In conclusion, raised urinary TGF-beta 1 was associated with HCC development. It is a predictor of poor prognosis, and a tumor marker for diagnosis and therapeutic follow-up of HCC.

Abstract
Considerable progress has been made recently in understanding the molecular mechanisms of angiogenesis, which like most other biological processes is the result of subtle and often complex interactions between molecules that have regulatory (eg, cytokines and their receptors) and effector (eg, extracellular matrix, integrins, and proteases) functions. The title of this review was chosen to reflect a recent trend in which knowledge acquired through a molecular/cell biological approach is being rapidly transferred to the clinical setting. As a result, by manipulating angiogenesis either positively or negatively, considerable therapeutic benefit can now be envisaged in physiological and pathological settings in which neovascularization is a prominent component.

Abstract
BACKGROUND Our aim was to assess the relationship between transforming growth factor beta 1 (TGF-beta 1) and alpha-fetoprotein (AFP) levels in hepatocellular carcinoma (HCC). METHODS Urinary TGF-beta 1 and serum AFP were determined in 123 HCC patients, 50 patients with chronic liver disease (CLD), and 50 healthy controls. RESULTS Both TGF-beta 1 and AFP levels were higher in HCC patients than in CLD patients or controls (each, P = 0.0001). There was a negative correlation between TGF-beta 1 and logAFP (r = -0.196, P = 0.029). Multivariate analysis indicated that TGF-beta 1 and AFP were associated with an increased risk of HCC development. By receiver-operating characteristic curve analysis, determination of AFP and TGF-beta 1 in parallel significantly increased the sensitivity and diagnostic accuracy in detecting HCC. CONCLUSION Increased urinary TGF-beta 1 level can be used as a complementary marker to AFP for detection of HCC with low AFP production.

Abstract
To assess the clinical relevance of transforming growth factor-beta1 (TGF-beta1) in hepatocellular carcinoma (HCC), urinary TGF-beta1 and serum alpha-fetoprotein (AFP) were determined in 94 patients with cirrhotic HCC, 94 age- and sex-matched patients with cirrhosis alone and 50 healthy adults. TGF-beta1 level in HCC was higher than in cirrhosis alone or in healthy controls (each P = 0.0001). There is an inverse correlation between TGF-beta1 and AFP levels (r = -0.292, P = 0.004). Significantly higher TGF-beta1 level was found in HCC patients with worsening Child-Pugh stages, diffuse HCC, tumour size > 3 cm, multilobular tumour and AFP < or = 20 ng ml(-1). TGF-beta1 level decreased after complete treatment with transcatheter arterial chemoembolization (P = 0.0001). The median survival in HCC patients with raised TGF-beta1 was shorter than those with normal TGF-beta1 (P = 0.018). Multivariate analysis indicated that TGF-beta1 and AFP were significantly correlated with the presence of HCC. In addition, TGF-beta1 could be used as a diagnostic marker for HCC, particularly in tumours with low AFP production. In conclusion, elevated urinary TGF-beta1 level is a tumour marker and predictor of poor survival for cirrhotic HCC.

To evaluate the diagnostic application of urinary transforming growth factor-beta1 (TGF-beta1) and serum alpha-fetoprotein (AFP) levels in hepatocellular carcinoma (HCC), TGF-beta1 and AFP were determined in 94 patients with cirrhotic HCC and in 94 sex- and age-matched patients with cirrhosis alone. TGF-beta1 and AFP levels in HCC were higher than in cirrhosis alone (P = 0.0001). There is an inverse correlation between TGF-beta1 and log AFP (r = -0.292, P = 0.004). Multivariate analysis indicated that TGF-beta1 and AFP were closely associated, in a dose-related fashion, with the development of HCC. Receiver-operating characteristic (ROC) curves were used to determine the optimal cut-off values of TGF-beta1 (50 microg g(-1) creatinine) and AFP (100 ng ml(-1)). Both TGF-beta1 and AFP showed a high specificity (99%) and positive likelihood ratio. The sensitivity was 53.1% for TGF-beta1 and 55.3% for AFP. The determination of both markers in parallel significantly increased the diagnostic accuracy (90.1%) and sensitivity (84%), with a high specificity (98%) and positive likelihood ratio (40.0). In conclusion, TGF-beta1 and AFP are independent tumour markers of HCC and may be used as complementary tumour markers to discriminate HCC from cirrhosis.

Abstract
PURPOSE To determine the frequency with which elevated plasma transforming growth factor-beta 1 (TGF beta 1) concentrations occur in lung cancer patients, to determine the kinetics of TGF beta 1 expression during and after radiotherapy and to correlate plasma TGF beta 1 levels with disease status after treatment. MATERIALS AND METHODS Plasma samples were obtained before, during and after radiotherapy in 54 patients with lung cancer and 20 normal controls. Plasma TGF beta 1 levels were measured using an enzyme-linked immunosorbent assay. RESULTS Baseline TGF beta 1 levels in lung cancer patients and normal controls were 13.0 +/- 2.5 and 4.4 +/- 0.3 ng/ml, respectively. Elevated TGF beta 1 were found in 50% (27/54) of lung cancer patients. During radiation therapy plasma TGF beta 1 levels declined, however, by the completion of treatment the mean TGF beta 1 level had not normalized in patients with lung cancer. The TGF beta 1 level at last follow-up correlated with disease status in those patients with an increased pretreatment plasma level. Three of four patients with no evidence of cancer had normal follow-up TGF beta 1 levels, compared to 2/16 patients with residual or recurrent tumor (P = 0.02). CONCLUSIONS Elevated plasma TGF beta 1 levels occur frequently in patients with lung cancer. In those patients with an elevated plasma TGF beta 1 level at diagnosis, monitoring this level may be useful in detecting both disease persistence and recurrence after therapy.

Abstract
In order to elucidate collagen metabolism in hepatocellular carcinoma (HCC) tissue, we compared levels of different potential markers of collagen metabolism and plasma transforming growth factor-beta 1 in patients with HCC and in patients with liver cirrhosis. Serum levels of prolyl hydroxylase and the tissue inhibitor of metalloproteinase-1 in patients with HCC were significantly higher than those in patients with liver cirrhosis and increased with the size of the HCC tumour, whereas the serum levels of procollagen type III propeptide and type IV collagen 7S domain were similar in the two groups. In HCC, the increased plasma transforming growth factor-beta 1 levels were closely correlated with serum levels of prolyl hydroxylase and the tissue inhibitor of metalloproteinase-1. These findings suggest that, in HCC tissue, the intracellular biosynthesis of collagen is enhanced, whereas the secretion of procollagen is disturbed and the degradation of collagen is suppressed by the excess production of the tissue inhibitor of metalloproteinase-1. The results also suggest that plasma transforming growth factor-beta 1 plays an important role in the altered metabolism of collagen in HCC.

Abstract
The sensitivity of normal tissues rather than of the tumour usually limits the effectiveness of cancer treatment. The normal tissue side effects from chemotherapy and/or radiotherapy result from both direct cellular loss and the extensive fibrosis that develops at the site of injury. Recent evidence suggests that the cytokine, transforming growth factor beta (TGF beta), mediates this fibrogenic process. Herein, we provide evidence in support of the hypothesis that the fibrosis formation following therapy results not only from TGF beta produced locally in the injured normal tissue, but also from circulating TGF beta released by the tumour. Thus, therapy-induced normal tissue damage appears in part to be a local manifestation of a systemic condition.

Abstract
Assays which measure active and latent forms of transforming growth factor beta (TGF-beta) separately in human serum and plasma are required to investigate the biological role of TGF-beta in a variety of human diseases. We have developed an enzyme-linked immunosorbent assay (ELISA) using two polyclonal antibodies against TGF-beta which rapidly determines the amount of active plus acid-activatable, latent TGF-beta forms ((a+l)TGF-beta) present in human serum and plasma in the range 4 pmol/l to 2000 pmol/l. To measure active TGF-beta alone, we have developed a second ELISA using the extracellular domain of the TGF-beta type II receptor as the capture reagent which detects active TGF-beta in serum and plasma samples in the range 20 pmol/l to 4000 pmol/l. Both assays detect TGF-beta 1 and TGF-beta 3 with similar sensitivity, are > 10-fold less sensitive to TGF-beta 2 and are not affected by a range of other peptide growth factors. The mean (a+l)TGF-beta present in human serum was 330 pmol/l but the range was very large (< 4 pmol/l to 1400 pmol/l). The mean active TGF-beta present was 230 pmol/l (range < 20 pmol/l to 1400 pmol/l) and the proportion of the (a+l)TGF-beta present which was active [a/(a+l)] varied from < 10% to 100%. The concentration of (a+l)TGF-beta and the proportion of TGF-beta which was active were very similar in the serum and platelet-poor plasma prepared from the same whole blood sample. The clot formed during serum preparation retained all of the TGF-beta which was detected by the (a+l)TGF-beta ELISA in the corresponding platelet releasate, although the PDGF in platelets was released into the serum. In contrast, platelet-poor plasma contained no detectable PDGF demonstrating that the (a+l)TGF-beta assayed in the plasma was not due to platelet degranulation after bleeding. Serum active TGF-beta and (a+l)TGF-beta concentrations therefore provide a reliable estimate of these forms of TGF-beta present in plasma.

Abstract
Transforming growth factor-beta 1 (TGF-beta 1) has been implicated in tumor progression by promoting angiogenesis or suppressing immune system. We reported previously that transforming growth factor-beta 1 (TGF-beta 1) is overproduced by human hepatocellular carcinoma (HCC) tissues and that plasma TGF-beta 1 levels are elevated in patients with HCC. In the present study, we investigated the relationship between plasma TGF-beta 1 levels and tumor vascularity as assessed by conventional celiac angiography in 17 patients with HCC. The plasma TGF-beta 1 level did not correlate with tumor size or underlying liver disease. However, we found that plasma TGF-beta 1 levels correlated positively with the tumor vascularity. These results suggest that excessive TGF-beta 1 production may contribute to tumor angiogenesis in HCC.
