Summary

This summary is machine-generated.

Integrin α7 (ITGA7) impacts cancer prognosis across multiple tumor types. Its abnormal expression correlates with poor outcomes and metastasis, suggesting ITGA7 as a potential cancer biomarker.

Area Of Science

  • Oncology
  • Molecular Biology
  • Genomics

Background

  • Integrins, such as Integrin α7 (ITGA7), are crucial cell adhesive molecules involved in numerous biological pathways.
  • While ITGA7's role in cancer is suggested, a comprehensive pan-cancer analysis was lacking.

Purpose Of The Study

  • To investigate the pan-cancer function of ITGA7 using multi-omics data.
  • To identify ITGA7-related regulatory RNAs through CeRNA networks.
  • To assess ITGA7's prognostic and predictive value across diverse cancer types.

Main Methods

  • Utilized multi-omics data for a pan-cancer analysis of ITGA7.
  • Constructed CeRNA networks to identify key regulatory RNAs.
  • Analyzed gene alteration data and cancer-associated fibroblast infiltration.
  • Performed gene enrichment analysis for ITGA7-correlated genes.

Main Results

  • ITGA7 expression varies significantly across different tumors.
  • Altered ITGA7 expression (overexpression or downregulation) correlates with poorer overall survival (OS) and progression-free survival (PFS) in specific cancers (e.g., BLCA, PAAD, UVM).
  • ITGA7 amplification impacts Kidney Chromophobe prognosis, and its expression is linked to cancer-associated fibroblast infiltration in 20 tumor types.
  • Enrichment analysis revealed ITGA7's involvement in cell adhesion and focal adhesion pathways.

Conclusions

  • Abnormal ITGA7 expression is associated with poor prognosis and metastasis in various cancers.
  • ITGA7 may serve as a valuable biomarker for predicting cancer prognosis and preventing complications.

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...

mTOR Signaling and Cancer Progression 03:03

3.8K

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 mTOR pathway or the...

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.

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...

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...
