Insights

Long non-coding RNA GHET1 promotes gastric cancer growth by stabilizing c-Myc. This finding suggests GHET1 as a potential target for gastric carcinoma treatment and prognosis.

Area of Science:

  • Molecular Biology
  • Oncology
  • Genetics

Background:

  • Long non-coding RNAs (lncRNAs) are regulatory molecules implicated in various cancers.
  • The specific roles of lncRNAs in gastric carcinoma remain largely undefined.

Purpose of the Study:

  • To investigate the role of lncRNA-GHET1 in gastric carcinoma.
  • To elucidate the functional mechanisms underlying GHET1's involvement in gastric cancer progression.

Main Methods:

  • Quantitative analysis of lncRNA-GHET1 expression in gastric carcinoma tissues.
  • In vitro and in vivo gain- and loss-of-function experiments.
  • RNA pull-down, immunoprecipitation, and correlation analyses to identify molecular interactions.

Main Results:

  • lncRNA-GHET1 is upregulated in gastric carcinoma and correlates with tumor size, invasion, and poor survival.
  • GHET1 overexpression promotes gastric carcinoma cell proliferation, while its knockdown inhibits it.
  • GHET1 binds to IGF2BP1, enhancing c-Myc mRNA stability and expression, which drives proliferation.

Conclusions:

  • lncRNA-GHET1 promotes gastric carcinoma cell proliferation by stabilizing c-Myc mRNA.
  • GHET1 represents a potential prognostic biomarker and therapeutic target for gastric carcinoma.

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...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...

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.
The mTOR pathway or the...

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:
