Abstract
In previous studies, NOX4, PDE11A and GHR genes have been screened as important candidate genes for litter size in sheep by using the GWAS method; however, neither their effects on litter size nor the loci associated with litter size have been identified. In this study, three candidate loci (c.1057-4C > T in NOX4, c.1983C > T in PDE11A and c.1618C > T in GHR) were first screened based on our previous resequencing data of 10 sheep breeds. After the three loci were genotyped using Sequenom MassARRAY technology, we carried out population genetics analysis on the three loci and performed association analysis between the polymorphism of the three loci and the litter size of sheep. The results of population genetics analysis suggested that c.1057-4C > T in NOX4 and c.1983C > T in PDE11A may be subject to natural or artificial selection. The results of association analysis indicated that litter size was significantly associated with c.1057-4C > T in NOX4 and c.1983C > T in PDE11A (p < 0.05) in Small Tail Han sheep, and there was no significant interaction effect between the two loci on the litter size. In summary, c.1057-4C > T in NOX4 and c.1983 C > T in PDE11A can be considered candidate molecular markers for improving litter size in sheep.

Sertoli cell-enriched proteins in mouse and human testicular interstitial fluid. PLoS One 2023; 18:e0290846.

Abstract
Sertoli cells support the development of sperm and the function of various somatic cells in the interstitium between the tubules. Sertoli cells regulate the function of the testicular vasculature and the development and function of the Leydig cells that produce testosterone for fertility and virility. However, the Sertoli cell-derived factors that regulate these cells are largely unknown. To define potential mechanisms by which Sertoli cells could support testicular somatic cell function, we aimed to identify Sertoli cell-enriched proteins in the testicular interstitial fluid (TIF) between the tubules. We previously resolved the proteome of TIF in mice and humans and have shown it to be a rich source of seminiferous tubule-derived proteins. In the current study, we designed bioinformatic strategies to interrogate relevant proteomic and genomic datasets to identify Sertoli cell-enriched proteins in mouse and human TIF. We analysed proteins in mouse TIF that were significantly reduced after one week of acute Sertoli cell ablation in vivo and validated which of these are likely to arise primarily from Sertoli cells based on relevant mouse testis RNASeq datasets. We used a different, but complementary, approach to identify Sertoli cell-enriched proteins in human TIF, taking advantage of high-quality human testis genomic, proteomic and immunohistochemical datasets. We identified a total of 47 and 40 Sertoli cell-enriched proteins in mouse and human TIF, respectively, including 15 proteins that are conserved in both species. Proteins with potential roles in angiogenesis, the regulation of Leydig cells or steroidogenesis, and immune cell regulation were identified. The data suggests that some of these proteins are secreted, but that Sertoli cells also deposit specific proteins into TIF via the release of extracellular vesicles. In conclusion, we have identified novel Sertoli cell-enriched proteins in TIF that are candidates for regulating somatic cell-cell communication and testis function.

Glypican 1 and syndecan 1 differently regulate noradrenergic hypertension development: Focus on IP3R and calcium. Pharmacol Res 2021; 172:105813. [PMID: 34411733 PMCID: PMC10200078 DOI: 10.1016/j.phrs.2021.105813] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 08/02/2021] [Accepted: 08/11/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND Vascular dysfunction is a checkpoint to the development of hypertension. Heparan sulfate proteoglycans (HSPG) participate in nitric oxide (NO) and calcium signaling, key regulators of vascular function. The relationship between HSPG-mediated NO and calcium signaling and vascular dysfunction has not been explored. Likewise, the role of HSPG on the control of systemic blood arterial pressure is unknown. Herein, we sought to determine if the HSPG syndecan 1 and glypican 1 control systemic blood pressure and the progression of hypertension. PURPOSE To determine the mechanisms whereby glypican 1 and syndecan 1 regulate vascular tone and contribute to the development of noradrenergic hypertension. EXPERIMENTAL APPROACH AND KEY RESULTS By assessing systemic arterial blood pressure we observed that syndecan 1 (Sdc1-/-) and glypican 1 (Gpc1-/-) knockout mice show a similar phenotype of decreased systolic blood pressure that is presented in a striking manner in the Gpc1-/- strain. Gpc1-/- mice are also uniquely protected from a norepinephrine hypertensive challenge failing to become hypertensive. This phenotype was associated with impaired calcium-dependent vasoconstriction and altered expression of calcium-sensitive proteins including SERCA and calmodulin. In addition, Gpc1-/- distinctively showed decreased IP3R activity and increased calcium storage in the endoplasmic reticulum. CONCLUSIONS AND IMPLICATIONS Glypican 1 is a trigger for the development of noradrenergic hypertension that acts via IP3R- and calcium-dependent signaling pathways. Glypican 1 may be a potential target for the development of new therapies for resistant hypertension or conditions where norepinephrine levels are increased.

Syndecan-4 as a Pathogenesis Factor and Therapeutic Target in Cancer. Biomolecules 2021; 11:biom11040503.

Abstract
Cancer is an important cause of morbidity and mortality worldwide. Advances in research on the biology of cancer revealed alterations in several key pathways underlying tumorigenesis and provided molecular targets for developing new and improved existing therapies. Syndecan-4, a transmembrane heparan sulfate proteoglycan, is a central mediator of cell adhesion, migration and proliferation. Although several studies have demonstrated important roles of syndecan-4 in cell behavior and its interactions with growth factors, extracellular matrix (ECM) molecules and cytoskeletal signaling proteins, less is known about its role and expression in multiple cancer. The data summarized in this review demonstrate that high expression of syndecan-4 is an unfavorable biomarker for estrogen receptor-negative breast cancer, glioma, liver cancer, melanoma, osteosarcoma, papillary thyroid carcinoma and testicular, kidney and bladder cancer. In contrast, in neuroblastoma and colorectal cancer, syndecan-4 is downregulated. Interestingly, syndecan-4 expression is modulated by anticancer drugs. It is upregulated upon treatment with zoledronate and this effect reduces invasion of breast cancer cells. In our recent work, we demonstrated that the syndecan-4 level was reduced after trastuzumab treatment. Similarly, syndecan-4 levels are also reduced after panitumumab treatment. Together, the data found suggest that syndecan-4 level is crucial for understanding the changes involving in malignant transformation, and also demonstrate that syndecan-4 emerges as an important target for cancer therapy and diagnosis.

Alteration of cell membrane proteoglycans impairs FSH receptor/Gs coupling and ERK activation through PP2A-dependent mechanisms in immature rat Sertoli cells. Biochim Biophys Acta Gen Subj 2013; 1830:3466-75. [PMID: 23500014 DOI: 10.1016/j.bbagen.2013.02.027] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2012] [Revised: 02/20/2013] [Accepted: 02/27/2013] [Indexed: 01/03/2023]
Abstract
BACKGROUND During the pre-pubertal life, the cessation of Sertoli cell proliferation and the onset of differentiation are associated with a shift in the FSH-mediated signaling leading to inhibition of the ERK-mitogenic pathway and to a concomitant sensitization of cAMP/PKA pathway. METHODS To highlight the role of cell proteoglycans (PGs) in the shift of FSH signaling, both FSH-induced cAMP production and ERK1/2 inactivation were studied in untreated and sodium chlorate PG-depleted cultured Sertoli cells from 20day-old rats. RESULTS Depletion of cell membrane PGs by sodium chlorate reduced FSH-, but not cholera toxin-stimulated cAMP production as well as basal ERK phosphorylation through an okadaic acid (OA)-sensitive mechanism. Involvement of PP2A was further substantiated by a marked decrease in membrane- associated PP2A activity under SC conditions and by the OA-induced restoration of PKA-dependent ERK inactivation in SC-treated cells. CONCLUSIONS In 20-day-old rat Sertoli cells, transmembrane cell PGs, through tethering/activation of PP2A activity exerts regulatory control on both FSH receptor/Gs coupling and ERK phosphorylation. GENERAL SIGNIFICANCE Besides their antiproliferative roles, cell PGs such as syndecan-1, could be involved in the increase in cAMP response to FSH occurring in Sertoli cells at the time of transition between proliferative and differentiated states.

Abstract
Binding of growth factors to specific cell surface receptors is the first step in initiating cell signaling cascades that ultimately result in diverse activities such as proliferation, differentiation, and apoptosis. Dimerization and phosphorylation of tyrosine kinase transmembrane receptors is the typical paradigm for this activation but, for many growth factors, cell surface interactions are not limited to a single receptor type. In particular, heparin-binding growth factors, such as fibroblast growth factor-2 (FGF-2), bind to heparan sulfate proteoglycans (HSPG) on the cell surface and within the extracellular matrix (ECM), and these molecules have been viewed as accessory co-receptors serving to facilitate tyrosine kinase receptor binding. Recent studies, however, have indicated that HSPG can directly participate in signal transduction in response to FGF-2 binding. Thus, in the present study, we used mathematical modeling to examine whether the kinetics of formation of the various FGF-2 bound complexes on the cell surface correlate with the activation of the downstream mediators of FGF-2 response, Erk1/2. We find that FGF-2 binding to its receptor correlates well with Erk1/2 activation and that HSPG can modulate this response through its ability to stabilize these ligand receptor complexes. Moreover, we also observed that FGF-2 binding to HSPG correlates strongly with Erk1/2 activation under conditions where there is a loss of receptor activity, and we demonstrate that the relative amounts of signaling and non-signaling HSPG on the cell surface, as well as the presence of competing HSPG in the ECM, can impact the signal potential via this pathway. Thus, the selective regulation of specific HSPG might provide a mechanism for fine tuned modulation of heparin-binding growth factor signaling in cells where signal intensity and duration could direct cellular response toward growth, migration or differentiation.
