Abstract

Insights

Long noncoding RNA SChLAP1 promotes bladder cancer progression. Inhibiting SChLAP1 in bladder cancer cells reduced proliferation and migration, suggesting it as a therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Long noncoding RNAs (lncRNAs) are increasingly recognized for their roles in cancer development.
  • SChLAP1, a lncRNA, is crucial for prostate cancer progression.
  • The role of SChLAP1 in other urological cancers, like bladder cancer, remains largely unexplored.

Purpose of the Study:

  • To investigate the expression and function of SChLAP1 in human bladder cancer.
  • To determine if SChLAP1 plays a role in bladder cancer cell growth, apoptosis, and migration.

Main Methods:

  • Real-time quantitative PCR (qPCR) was used to measure SChLAP1 expression in bladder cancer tissues and cell lines.
  • Bladder cancer cell lines (T24 and 5637) were transfected with SChLAP1 siRNA to inhibit its expression.
  • Cell proliferation, apoptosis, and migration were assessed using CCK-8 assay, flow cytometry, and wound healing assays, respectively.

Main Results:

  • SChLAP1 was significantly overexpressed in bladder cancer tissues compared to normal adjacent tissues.
  • Inhibition of SChLAP1 using siRNA led to cell growth arrest in bladder cancer cells.
  • SChLAP1 knockdown induced apoptosis and inhibited migration in T24 and 5637 bladder cancer cells.

Conclusions:

  • SChLAP1 exhibits oncogenic properties in human bladder cancer.
  • SChLAP1 represents a potential therapeutic target for bladder cancer treatment.

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

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...

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...

RNA Interference01:23

RNA Interference

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
