Abstract

Insights

Altered pseudogene expression, including RCN1P2, TPM3P9, and HSP90AB3P, is linked to gastric cancer (GC) progression. These pseudogenes influence cell proliferation, inflammation, and metastasis through the competing endogenous RNA network, impacting patient survival.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genomics

Background:

  • Gastric cancer (GC) pathogenesis involves complex molecular alterations.
  • Pseudogenes, non-coding RNAs, are increasingly recognized for their roles in cancer development.

Purpose of the Study:

  • Identify pseudogenes with altered expression in GC.
  • Investigate their role in GC development via the competing endogenous RNA (ceRNA) network.

Main Methods:

  • Utilized TCGA data (2006-2017) to identify differentially expressed pseudogenes, mRNAs, and microRNAs in GC.
  • Constructed a ceRNA network using miRWalk, miRTarBase, and DIANA-LncBase.
  • Validated in-silico findings using RT-qPCR on GC and adjacent normal tissue samples.

Main Results:

  • Identified 33 pseudogenes with significant expression changes in GC.
  • Pseudogenes RCN1P2, TPM3P9, and HSP90AB3P showed high connectivity within the ceRNA network.
  • Upregulated pseudogenes were associated with pathways in cell proliferation, inflammation, and metastasis, correlating with poor prognosis.

Conclusions:

  • Pseudogenes RCN1P2, TPM3P9, and HSP90AB3P are significantly upregulated in GC.
  • These pseudogenes potentially drive GC progression by modulating key cellular pathways via the ceRNA network, affecting patient survival.

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 Nucleolus02:55

The Nucleolus

The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

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...

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...

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.

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
