Summary

This summary is machine-generated.

This study identified 12 long non-coding RNA (lncRNA) genes associated with a strong immune response and positive cancer prognosis. Two lncRNAs show potential as biomarkers for predicting patient outcomes and immune cell infiltration.

Area Of Science

  • Genomics and Molecular Biology
  • Cancer Research
  • Immunology

Background

  • Long non-coding RNAs (lncRNAs) play crucial roles in cellular processes.
  • lncRNAs are increasingly recognized for their involvement in cancer development and progression.
  • Characterizing lncRNAs in cancer patients is essential for understanding their functional significance.

Purpose Of The Study

  • To identify and classify lncRNAs based on their association with immune response genes.
  • To investigate the relationship between lncRNAs and cancer prognosis.
  • To explore the potential of lncRNAs as biomarkers for cancer immunotherapy.

Main Methods

  • Differential expression analysis of 435 lncRNAs in 5,013 cancer patients.
  • Correlation analysis of 80 commonly expressed lncRNAs with immune response genes using Pearson's correlation and TIMMUSCORA.
  • Receiver operating characteristic (ROC) analysis to assess lncRNA association with tumor-infiltrating lymphocyte (TIL) status.
  • Multivariate Cox proportional hazards model for cancer prognostic analysis.

Main Results

  • 80 lncRNAs were identified and classified into high, intermediate, and low immune status score groups.
  • High-scoring lncRNAs demonstrated high sensitivity in identifying TILs, including CD8+ T cells and B cells.
  • 11 lncRNAs were identified as significant prognostic genes.

Conclusions

  • Twelve lncRNA genes with high immune scores were identified as immunogenic and associated with CD8+ T cell infiltration.
  • Two specific lncRNAs emerged as indicators of a positive cancer prognosis.
  • These 12 lncRNAs hold potential as biomarkers for predicting immune response and favorable prognosis in cancer patients.

9.8K

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...

The Tumor Microenvironment 02:17

7.6K

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Tumor Progression 02:07

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...

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...

Cancer Survival Analysis 01:21

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
