Insights

This article on LncRNA CASC15 in bladder cancer has been withdrawn due to suspected research misconduct. The publisher retracted the study after authors failed to verify data originality.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Long non-coding RNAs (lncRNAs) play critical roles in cancer development.
  • Aberrant expression of lncRNAs is implicated in various human malignancies, including bladder cancer.
  • Specific lncRNAs can act as competing endogenous RNAs (ceRNAs) to regulate gene expression through microRNA (miRNA) sponging.

Purpose of the Study:

  • To investigate the role of LncRNA CASC15 in bladder cancer.
  • To explore the interaction between LncRNA CASC15 and miR-130b-3p.
  • To determine if LncRNA CASC15 functions as an oncogene in bladder cancer.

Main Methods:

  • The study aimed to analyze the expression of LncRNA CASC15 and miR-130b-3p in bladder cancer tissues and cell lines.
  • Mechanisms of action were investigated through in vitro experiments, including cell proliferation, migration, and invasion assays.
  • Bioinformatic analyses and luciferase reporter assays were employed to confirm the sponging activity of LncRNA CASC15 on miR-130b-3p.

Main Results:

  • LncRNA CASC15 was found to be upregulated in bladder cancer.
  • Overexpression of LncRNA CASC15 promoted bladder cancer cell proliferation, migration, and invasion.
  • LncRNA CASC15 was identified to directly bind to miR-130b-3p, acting as a sponge.

Conclusions:

  • LncRNA CASC15 acts as an oncogene in bladder cancer by sponging miR-130b-3p.
  • LncRNA CASC15 may serve as a potential therapeutic target for bladder cancer treatment.

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...

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...

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...

Loss of Tumor Suppressor Gene Functions

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.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
