Abstract

Insights

Long non-coding RNA LINC00963 acts as an oncogene in bladder cancer. It promotes tumor progression by regulating the miR-766-3p/MTA1 pathway, suggesting a new therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Long non-coding RNAs (lncRNAs) play a role in cancer development.
  • LINC00963 is implicated in bladder cancer progression.

Purpose of the Study:

  • Investigate the role of LINC00963 in bladder cancer.
  • Identify LINC00963 as a potential therapeutic target.

Main Methods:

  • Analysis of 56 bladder cancer patients.
  • Cell viability, colony formation, migration, and invasion assays.
  • Quantitative real-time PCR, luciferase reporter, and RNA pulldown assays.
  • The Cancer Genome Atlas (TCGA) analysis for MTA1 expression.

Main Results:

  • LINC00963 is upregulated in bladder cancer, correlating with poor survival.
  • LINC00963 knockdown inhibits bladder cancer cell proliferation, migration, and invasion.
  • LINC00963 promotes metastasis-associated protein 1 (MTA1) expression by inhibiting miR-766-3p.
  • MTA1 upregulation reverses the inhibitory effects of LINC00963 knockdown.

Conclusions:

  • LINC00963 functions as an oncogene in bladder cancer.
  • The LINC00963/miR-766-3p/MTA1 axis drives bladder cancer progression.
  • LINC00963 represents a novel therapeutic target for bladder cancer.

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...

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).

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 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,...

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...
