Abstract

Insights

MicroRNA-1251-5p suppresses clear cell renal cell carcinoma (ccRCC) progression by targeting NPTX2. This finding offers new therapeutic strategies for ccRCC patients, highlighting miR-1251-5p as a potential biomarker.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • MicroRNA-1251-5p is a known tumor suppressor in various cancers.
  • Its specific role in clear cell renal cell carcinoma (ccRCC) remains unelucidated.

Purpose of the Study:

  • To investigate the function and mechanism of miR-1251-5p in ccRCC.
  • To explore miR-1251-5p as a potential therapeutic target and biomarker for ccRCC.

Main Methods:

  • Utilized TCGA and GEO databases for expression analysis of miR-1251-5p and target genes in ccRCC tissues.
  • Employed cell-based assays (MTT, colony formation, Transwell) and molecular techniques (dual-luciferase reporter, Western blot) to determine functional roles and mechanisms.
  • Bioinformatic analysis identified potential target mRNAs.

Main Results:

  • miR-1251-5p directly targets the 3'-UTR of NPTX2.
  • Lower miR-1251-5p and higher NPTX2 expression were observed in ccRCC tissues compared to normal tissues.
  • Both miR-1251-5p and NPTX2 serve as prognostic biomarkers for ccRCC patients.
  • miR-1251-5p significantly inhibited ccRCC cell proliferation, migration, and immune escape by targeting NPTX2.

Conclusions:

  • miR-1251-5p acts as a tumor suppressor in ccRCC by inhibiting cell proliferation, migration, and immune evasion through NPTX2.
  • These findings provide novel insights into targeted therapy for ccRCC.

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,...

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 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...

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...
