INHBE Antibody (1111910) [Unconjugated]

INHBE was detected in immersion fixed paraffin-embedded sections of human liver using Mouse Anti-Human INHBE Monoclonal Antibody (Catalog # MAB11746) at 5 µg/ml overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using the HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007) and counterstained with hematoxylin (blue). Specific staining was localized to the cytoplasm.

Background

Inhibin beta E (INHBE) is a member of the transforming growth factor-beta (TGF-beta ) superfamily of cytokines, with a molecular weight of approximately 40 kDa. INHBE plays critical roles in the regulation of diverse physiological processes, including cell growth, differentiation, and metabolism. It is a key component of the activin signaling pathway, where it dimerizes with other beta -subunits to form bioactive ligands involved in endocrine regulation. INHBE is primarily expressed in hepatic and reproductive tissues and has been implicated in metabolic homeostasis, particularly in energy expenditure and glucose metabolism. Dysregulation of INHBE expression has been linked to pathophysiological conditions such as obesity, insulin resistance, and liver disease. Furthermore, INHBE has gained attention for its tumor-suppressive role in certain cancers, suggesting its potential as a regulator of cell proliferation and apoptosis. Its specificity and involvement in metabolic and oncogenic pathways highlight INHBE as a promising biomarker and a potential target for therapeutic strategies.
