Summary

This summary is machine-generated.

The Cms1 ribosomal small subunit homolog (CMSS1) is upregulated in non-small cell lung cancer (NSCLC), correlating with poor prognosis. Downregulating CMSS1 inhibits tumor growth, suggesting it as a therapeutic target for NSCLC.

Area Of Science

  • Oncology
  • Molecular Biology
  • Immunology

Background

  • The Cms1 ribosomal small subunit homolog (CMSS1), an RNA-binding protein (RBP), is implicated in tumor development.
  • The prognostic and immunological significance of CMSS1 in non-small cell lung cancer (NSCLC) is not well understood.

Purpose Of The Study

  • To investigate the prognostic and immunological role of CMSS1 in NSCLC.
  • To evaluate CMSS1 as a potential therapeutic target and prognostic biomarker for NSCLC.

Main Methods

  • Utilized The Cancer Genome Atlas (TCGA) database to identify differentially expressed RBP genes.
  • Selected CMSS1 as a hub gene via univariate Cox regression and Kaplan-Meier analyses.
  • Assessed prognostic capacity using time-dependent ROC curves and multivariate Cox regression.
  • Analyzed tumor-infiltrating immune cells with the ImmuCellAI algorithm.
  • Performed loss-of-function assays to determine CMSS1's functional role in NSCLC cells.

Main Results

  • CMSS1 was significantly upregulated in NSCLC tumors, with higher expression linked to poorer patient prognosis.
  • CMSS1 expression correlated negatively with CD4 T cells and positively with macrophages and Tregs.
  • Loss-of-function assays demonstrated that CMSS1 downregulation inhibited NSCLC cell viability, migration, and invasion.
  • RT-qPCR and western blot confirmed elevated CMSS1 mRNA and protein levels in NSCLC cell lines.

Conclusions

  • CMSS1 may function as a prognostic indicator and a therapeutic target in NSCLC.
  • Findings offer potential guidance for precision therapy and prognosis prediction in NSCLC patients.

lncRNA - Long Non-coding RNAs 02:39

8.4K

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...

Abnormal Proliferation 02:23

4.4K

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...

MicroRNAs 01:22

21.0K

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...

Master Transcription Regulators 02:23

6.8K

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

RNA Splicing 01:32

55.8K

Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

The Nucleolus 02:55

The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
