Insights

Activin-βC, once overlooked, is now recognized for its crucial role in regulating cell functions and antagonizing activin signaling. This review highlights its importance in reproductive and cancer biology, including its impact on metabolism.

Area of Science:

  • Cellular biology
  • Molecular biology
  • Cancer research

Background:

  • Transforming growth factor-β (TGF-β) superfamily signaling regulates vital cellular processes.
  • Dysregulation of TGF-β signaling is linked to cancer progression.
  • Activin-βC, a TGF-β superfamily member, was historically underestimated.

Purpose of the Study:

  • To review recent advances in activin biology, focusing on activin-βC.
  • To elucidate the antagonistic mechanisms and physiological relevance of activin-βC.
  • To highlight novel roles in reproductive and cancer biology, including metabolism.

Main Methods:

  • Literature review of recent studies on activin-βC.
  • Analysis of activin-βC's antagonistic function.
  • Examination of activin-βC's role in reproductive and cancer contexts.

Main Results:

  • Activin-βC plays a significant role in cellular processes.
  • Activin-βC antagonizes the activin signaling pathway.
  • Activin-βC influences reproductive biology, cancer, and cancer-associated weight loss and muscle metabolism.

Conclusions:

  • Activin-βC's biological relevance requires re-evaluation.
  • Understanding activin-βC's function is critical for interpreting biological outcomes.
  • Further research into activin-βC is warranted, particularly in cancer and metabolism.

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
