Summary
This summary is machine-generated.This study identifies eight long non-coding RNAs and nine necroptosis-related genes that predict outcomes in colon adenocarcinoma (COAD). These genes influence immune responses and tumor progression, offering potential therapeutic targets for COAD patients.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Necroptosis plays a role in colon adenocarcinoma (COAD) initiation and progression.
- Limited research exists on necroptosis-related genes (NRGs) and their regulating long non-coding RNAs (NRGlncRNAs) in COAD.
- Understanding these molecular players is crucial for developing novel COAD diagnostics and therapeutics.
Purpose Of The Study
- To identify prognostic necroptosis-related genes (NRGs) and long non-coding RNAs (lncRNAs) in colon adenocarcinoma (COAD).
- To explore the regulatory mechanisms and potential causal relationships of these genes in COAD development.
- To establish a prognostic model for COAD based on identified NRGs and NRGlncRNAs.
Main Methods
- Utilized The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets for NRGs and NRGlncRNAs.
- Employed Cox and least absolute shrinkage and selection operator (LASSO) regression to build a prognostic risk model.
- Performed Mendelian randomization (MR) analysis, cell experiments, enrichment analysis, and immune-related analyses.
Main Results
- Identified eight prognostic NRGlncRNAs and nine prognostic NRGs significantly associated with COAD patient outcomes.
- Validated the prognostic model using independent GEO and GWAS datasets, showing consistent results.
- Demonstrated that these genes modulate immune responses, oxidative stress, and immune escape in COAD.
- High-risk groups exhibited increased immune cell infiltration and immune checkpoint gene expression.
Conclusions
- The identified NRGlncRNAs and NRGs serve as valuable prognostic indicators for COAD.
- These molecules offer potential therapeutic targets for improving clinical diagnosis and treatment of COAD.
- The study provides a foundation for further research into necroptosis-related pathways in COAD.

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 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...
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
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 the pre-miRNA...
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...
