Insights

Zinc-finger protein 304 (ZNF304) is downregulated in clear cell renal carcinoma (ccRCC), promoting tumor growth. Targeting the ZNF304/miR-183-5p/FOXO4 axis may offer new ccRCC therapies.

Area of Science:

  • Molecular Biology
  • Oncology
  • Gene Regulation

Background:

  • Zinc-finger protein 304 (ZNF304) is crucial for gene silencing and cellular processes.
  • The role and clinical significance of ZNF304 in clear cell renal carcinoma (ccRCC) are not well understood.

Purpose of the Study:

  • To investigate the role of ZNF304 in ccRCC progression.
  • To elucidate the molecular mechanism underlying ZNF304's function in ccRCC.

Main Methods:

  • Analysis of ZNF304 expression in ccRCC tissues.
  • In vitro studies on ccRCC cell growth.
  • Investigation of the miR-183-5p/FOXO4 pathway.
  • ZNF304 binding to the miR-183 promoter was assessed.

Main Results:

  • ZNF304 expression is downregulated in ccRCC and correlates with poor survival.
  • Reduced ZNF304 promotes ccRCC cell growth; its overexpression inhibits growth.
  • The ZNF304/miR-183-5p/FOXO4 axis regulates ccRCC cell growth, with ZNF304 inhibiting miR-183-5p transcription and promoting FOXO4 expression.
  • miR-183-5p is upregulated in ccRCC, associated with poor prognosis, and promotes ccRCC progression by repressing FOXO4.

Conclusions:

  • The ZNF304/miR-183-5p/FOXO4 axis is a key driver of ccRCC progression.
  • This axis represents a potential therapeutic target for ccRCC treatment.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

mTOR Signaling and Cancer Progression03:03

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.

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
