lncRNA - Long Non-coding RNAs

9.7K
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...

Tumor Progression02:07

Tumor Progression

7.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer-Critical Genes II: Tumor Suppressor Genes

9.3K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Loss of Tumor Suppressor Gene Functions

5.8K
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...

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Lower-grade gliomas (LGGs) are common brain tumors with unclear risk stratification.
  • Cuproptosis, a programmed cell death pathway linked to metabolism, and long noncoding RNAs (lncRNAs) are implicated in glioma progression.
  • The role of cuproptosis-related lncRNAs (CRLs) in LGG development requires further elucidation.

Purpose of the Study:

  • To identify CRLs associated with LGG prognosis and immune characteristics.
  • To develop a prognostic signature based on CRLs for LGG risk stratification.
  • To explore potential therapeutic targets and predict drug efficacy in LGG.

Main Methods:

  • Correlation analysis to identify 963 CRLs.
  • LASSO and multivariate Cox regression to construct a prognostic signature of four CRLs.
  • Gene set variation analysis (GSVA), gene set enrichment analysis (GSEA), ESTIMATE, and TIDE to analyze biological processes and immune landscapes.
  • Validation of drug efficacy and lncRNA function in vitro.

Main Results:

  • A four-gene prognostic signature (AC002456.1, TPRG1-AS1, AC098851.1, LYRM4-AS1) was developed, classifying LGG patients into distinct risk groups.
  • Significant differences in biological processes and immune landscapes were observed between risk groups.
  • The CRL signature correlated with immunotherapy effectiveness, and drugs like MG-132 showed anti-glioma effects in vitro.
  • Knockdown of TPRG1-AS1 and LYRM4-AS1 impaired glioma cell migration and proliferation.

Conclusions:

  • CRLs are significantly associated with prognosis and immune characteristics in LGG.
  • The developed CRL-based signature provides a novel tool for LGG risk stratification.
  • CRLs and identified drugs represent potential therapeutic strategies for LGG patients.
