Summary
This summary is machine-generated.Lys-Asp-Glu-Leu receptor (KDELR) genes are highly expressed in lung adenocarcinoma (LUAD), correlating with poor prognosis. Aberrant KDELR expression may be driven by epigenetic changes and regulatory networks, offering potential therapeutic targets.
Area Of Science
- Oncology
- Molecular Biology
- Bioinformatics
Background
- Lys-Asp-Glu-Leu receptor (KDELR) family genes are implicated in various tumor biological processes.
- Understanding KDELR roles in lung adenocarcinoma (LUAD) is crucial for targeted therapies.
Purpose Of The Study
- To comprehensively analyze the potential roles and regulatory mechanisms of KDELRs in LUAD.
- To identify KDELRs as potential prognostic markers and therapeutic targets for LUAD.
Main Methods
- Utilized The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases, alongside clinical samples.
- Performed bioinformatics analyses using R software and online resources, including GSEA and ceRNA network analysis.
- Investigated promoter methylation, transcription factor (TF) involvement, and immune cell infiltration correlations.
Main Results
- KDELR family genes and proteins exhibit high expression in LUAD, associated with poor patient prognosis.
- Aberrant KDELR1 overexpression may stem from promoter hypomethylation and a PCAT6/hsa-miR-326/KDELR1 ceRNA network.
- Identified key TFs (SPI1, EP300, MAZ) and a TF-miRNAs-KDELRs network potentially regulating KDELR expression.
- GSEA revealed enrichment of KDELR-high genes in MTORC1_SIGNALING, P53_PATHWAY, and ANGIOGENESIS.
- Found negative correlations between KDELR expression and CD8+ T cell infiltration and CTLA-4 expression.
Conclusions
- KDELRs function as significant signaling molecules in LUAD progression.
- Aberrant KDELR expression is linked to specific molecular mechanisms and immune evasion.
- KDELRs represent promising targets for novel prognostic markers and therapeutic strategies in LUAD.

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

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...
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...
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...
