Insights

Elevated SAGA-associated factor 29 (SGF29) drives hepatocellular carcinoma (HCC) by upregulating c-Myc. This deregulated Sry-SGF29 pathway may explain male-specific HCC development.

Area of Science:

  • Molecular biology
  • Oncology
  • Biochemistry

Background:

  • Deregulated c-Myc expression is a common feature in human cancers.
  • SAGA-associated factor 29 (SGF29), a component of the mammalian SPT3-TAF9-GCN5-acetyltransferase complex, regulates c-Myc.
  • Hepatocellular carcinoma (HCC) is a significant global health concern, with a notable male predominance.

Purpose of the Study:

  • To elucidate the molecular mechanism of SGF29 in regulating c-Myc overexpression in HCC.
  • To investigate the role of sex-determining region Y (Sry) in the upstream regulation of SGF29 in HCC.
  • To explore the hypothesis that deregulated Sry-SGF29 pathway contributes to male-specific HCC development.

Main Methods:

  • Analysis of the molecular nature of SGF29 within the SPT3-TAF9-GCN5-acetyltransferase complex.
  • Investigation of the mechanism linking elevated SGF29 expression to c-Myc's oncogenic potential in HCC.
  • Examination of Sry-mediated upstream regulation of SGF29 in HCC models.

Main Results:

  • SGF29 plays a crucial role in regulating c-Myc overexpression in HCC.
  • Elevated SGF29 expression contributes to the oncogenic potential of c-Myc in HCC.
  • Sry-mediated regulation of SGF29 is augmented in HCC, suggesting a link to male-specific tumorigenesis.

Conclusions:

  • The Sry-SGF29 pathway is a key driver of c-Myc elevation in HCC.
  • This pathway is implicated in the male-specific incidence of human HCC.
  • Targeting the Sry-SGF29-c-Myc axis may offer novel therapeutic strategies for HCC.

Liver Regeneration01:24

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

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...

Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
