Abstract
Members of the transforming growth factor β (TGF-β) family have been implicated in the biology of several cancers. In this review, we focus on the role of TGFβ and bone morphogenetic protein (BMP) signaling in glioblastoma. Glioblastoma (GBM) is the most common malignant brain tumor in adults; it presents at a median age of 64 years, but can occur at any age, including childhood. Unfortunately, there is no cure, and even patients undergoing current treatments (surgical resection, radiotherapy, and chemotherapy) have a median survival of 15 months. There is a great need to identify new therapeutic targets to improve the treatment of GBM patients. TGF-βs signaling promotes tumorigenesis in glioblastoma, while BMPs suppress tumorigenic potential by inducing tumor cell differentiation. In this review, we discuss the actions of TGF-βs and BMPs on cancer cells as well as in the tumor microenvironment, and their use in potential therapeutic intervention.

Abstract
The objective of this study was to identify the gonadal somatic cells in the Yesso scallop using a novel molecular marker. This study is the first to identify the bone morphogenetic protein 2a (Bmp2a) gene as a gonadal somatic cell-specific gene in this bivalve. We performed a transcriptomic survey to identify the transforming growth factor-β (TGFβ) superfamily members that act in Yesso scallop gonad development. BLAST survey, phylogenetic tree, and RT-PCR analyses screened BMP molecules (i.e., bmp2a and bmp10a), which are members of the TGFβ superfamily that show gonad-specific expression. Among the BMPs from the Yesso scallop, in situ hybridization accompanied by RNAscope assay identified that bmp2a mRNA was specifically expressed in the gonadal somatic cells localized in the interspace between germ cells. Real-time quantitative PCR (qPCR) analysis revealed that bmp2a mRNA expression increased during the reproductive phase. The relative expression of bmp2a mRNA was lowest at the beginning of the growing stage and peaked at the mature stage in both sexes. These observations indicate that bmp2a-positive gonadal somatic cells support germ cell growth and differentiation during the reproductive phase for both sexes. This study provides new insights into gonadal somatic cell biology in marine invertebrates and we propose that TGFβ signaling is necessary for gonad development in bivalves.

Abstract
During embryonic development in vertebrates, morphogens play an important role in cell fate determination and morphogenesis. Bone morphogenetic proteins (BMPs) belonging to the transforming growth factor-β (TGF-β) family control the dorsal-ventral (DV) patterning of embryos, whereas other morphogens such as fibroblast growth factor (FGF), Wnt family members, and retinoic acid (RA) regulate the formation of the anterior-posterior (AP) axis. Activation of morphogen signaling results in changes in the expression of target genes including transcription factors that direct cell fate along the body axes. To ensure the correct establishment of the body plan, the processes of DV and AP axis formation must be linked and coordinately regulated by a fine-tuning of morphogen signaling. In this review, we focus on the interplay of various intracellular regulatory mechanisms and discuss how communication among morphogen signaling pathways modulates body axis formation in vertebrate embryos.

Abstract
The aim of this study was to investigate some of the growth and transcriptional factors originating from oocytes and granulosa cells in follicular fluid and to identify the relationships between the basic blood metabolite-metabolic hormones and intrafollicular lipopolysaccharide (LPS) concentrations. Thirty cows included in the study were allocated into 2 groups comprising 15 cows with healthy preovulatory follicles (cyclic cows) and 15 cows with confirmed cystic follicles. The ovaries and uteri of all cows were assessed by transrectal ultrasonographic examination. Blood serum samples were collected at 15, 25, 35, 45, and 55 d after calving for analysis of nonesterified fatty acids, β-hydroxybutyrate, insulin, glucose, IGF-I, ACTH, and cortisol. Ovaries and uteri were examined using transrectal ultrasound. Vaginal discharge was evaluated on the same days. Follicular fluid was also aspirated on days 35-55 from the healthy preovulatory follicles and cystic follicles using a transvaginal ovum pickup method. The densitometric levels of inhibin-α, growth and differentiation factor (GDF-9), bone morphogenetic protein (BMP-6), and GATA-4 and GATA-6 proteins were analyzed by the Western blotting technique; the concentrations of antimullerian hormone (AMH), IGF-I, estradiol-17 beta (E2), and progesterone (P4) were determined by ELISA; and the concentrations of LPS in the follicular fluid were measured by the Limulus amebocyte lysate test. The serum insulin, ACTH, and cortisol concentrations were higher in cystic cows than cyclic cows, but serum IGF-I concentrations were lower in cystic cows. The IGF-I concentrations of cystic follicular fluids were lower, whereas AMH levels were significantly greater than those of healthy preovulatory follicular fluids. The cystic follicles had significantly lower expression levels of GDF-9, BMP-6, GATA-4, and GATA-6; in contrast, inhibin-α expression and LPS concentrations were significantly higher than in healthy preovulatory follicles. The proportion of pathologic vaginal discharge within 25 d postpartum in cystic cows were higher than in the cyclic group. In conclusion, it is suggested that intrafollicular dysregulation of the transforming growth factor-β superfamily, growth, and transcriptional factors is affected by high intrafollicular LPS concentrations and systemic metabolic changes and these disturbances may be responsible for the generation of ovarian cysts.

Association of Transforming Growth Factor-β Superfamily Genes with Non-Regression of Pulmonary Artery Hypertension Following Balloon Mitral Valvotomy: A Pilot Study.

Abstract
BACKGROUND AND AIM OF THE STUDY Pulmonary arterial hypertension (PAH) is a common accompaniment of rheumatic mitral stenosis (MS), with 70% of patients showing evidence of different grades of PAH. The latter condition is found to be a prognostic factor influencing disease outcome even after interventional or surgical therapy. The cause of the non-regression of PAH following successful balloon mitral valvotomy (BMV) is not clear. Hence, the study aim was to determine if there is an association of mutations in the genes of the TGF-β superfamily and non-regression of PAH in patients who undergo a successful BMV. METHODS Forty-six patients who underwent BMV and fulfilled the recruitment criteria were enrolled prospectively in this case-control study. Among the patients, 27 had non-regression of PAH while 19 had regression of PAH and served as controls. The mean age of the population was 32.63 ± 10.65 years. RESULTS No statistically significant differences were identified in any of the baseline parameters between the two groups. None of the samples had BMPR2 or ACVRL1 mutations. Ten of the patients and four of the controls were positive for Endoglin mutation, but the inter-group difference was not statistically significant (p = 0.25) CONCLUSIONS: The present study - the first of its kind - showed that deletion-duplication mutations in the BMPR2 or ACVRL1 genes may not be associated with non-regression of PAH, even after successful BMV, or in a wider sense serve as a contributor to PAH in rheumatic MS. The association of Endoglin mutation and non-regression of PAH warrants further investigation in a larger population.

Abstract
Marfan syndrome is an autosomal dominant disorder, characterized by tall stature, long arms and legs, ectopia lentis, and aortic aneurysms and dissections. Recent research has revealed that these phenotypes are caused by mutations in fibrillin-1, the major structural component of elastic microfibrils, and the continuing dysregulation of transforming growth factor beta (TGFbeta) signaling is principally considered to be contributing to the pathophysiological background of the disease. Blockade of TGFbeta signaling by angiotensin II receptor antagonism is a novel promising therapeutic option, and thus such large clinical randomized controlled trials are underway. Here, we review the past development, current status and future perspectives in the research field for Marfan syndrome.

Abstract
Inhibins and activins are members of the transforming growth factor (TGFβ) superfamily, that includes the TGFβs, inhibins and activins, bone morphogenetic proteins (BMPs) and growth and differentiation factors (GDFs). The family members are expressed throughout the human body, and are involved in the regulation of a range of important functions. The precise regulation of the TGFβ pathways is critical, and mutations of individual molecules or even minor alterations of signalling will have a significant affect on function, that may lead to development of disease or predisposition to the development of disease. The inhibins and activins regulate aspects of the male and female reproductive system, therefore, it is not surprising that most of the diseases associated with abnormalities of the inhibin and activin genes are focused on reproductive disorders and reproductive cancers. In this review, I highlight the role of genetic variants in the development of conditions such as premature ovarian failure, pre-eclampsia, and various reproductive cancers. Given the recent advances in human genetic research, such as genome wide association studies and next generation sequencing, it is likely that inhibins and activins will be shown to play more important roles in a range of human genetic diseases in the future.

Abstract
Smad proteins are intracellular molecules that mediate the canonical signaling cascade of TGFbeta superfamily growth factors. The TGFbeta superfamily comprises two groups of growth factors, BMPs and TGFbetas. Both groups can be further divided into several sub-groups based on sequence homologies and functional similarities. Ligands of the TGFbeta superfamily bind to cell surface receptors to activate Smad proteins in the cytoplasm; then the activated Smad proteins translocate into the nucleus to activate or repress specific target gene transcription. Both groups of growth factors play important roles in skeletal development and regeneration. However, whether these effects reflect signaling through canonical Smad pathways, or other non-canonical signaling pathways in vivo remains a mystery. Moreover, the mechanisms utilized by Smad proteins to initiate nuclear events and their interactions with cytoplasmic proteins are still under intensive investigation. This review will discuss the most recent progress understanding Smad signaling in the context of skeletal development and regeneration.

Abstract
Extracellular domains of some cellular receptors expressed in the organisms at different levels of development belong to three-fingered protein (TFP) fold. The Homo sapiens genome encodes at least 45 genes containing from one to three TFP domains (TFPDs), namely diverse paralogues of the Ly6 gene, CD59 and the receptors of activins, bone morphogenetic proteins, Mullerian inhibiting substance and transforming growth factor-beta. C4.4a and urokinase/plasminogen activatory receptor contain two and three TFPD repeats, respectively. These diverse proteins have a low overall sequence similarity with each other and their hydrophobicity levels vary to a considerable degree. It is suggested that sequence differentiation within the TFPD led to distinct groups of proteins whose attributes were optimized to fit both the physicochemical properties specific to their functional microenvironment and selective targeting of their highly diversified extracellular cofactors.
