Abstract:
The scavenger receptor cysteine-rich (SRCR) proteins, with one to several SRCR domains, play important roles in human diseases. A full view of their functions in esophageal squamous cell carcinoma (ESCC) remain unclear. Sequence alignment and phylogenetic tree for all human SRCR domains were performed. Differentially-expressed SRCR genes were identified in ESCC, followed by protein-protein interaction (PPI) network construction, topological parameters, subcellular distribution, functional enrichment and survival analyses. The variation of conserved cysteines in each SRCR domain suggested a requirement for new classification of the SRCR family. Six genes (LGALS3BP, MSR1, CD163, LOXL2, LOXL3 and LOXL4) were upregulated, and four genes (DMBT1, PRSS12, TMPRSS2 and SCARA5) were downregulated in ESCC. These 10 SRCR genes form a unique biological network. Functional enrichment analyses provided important clues to investigate the biological functions for SRCR gene network in ESCC, such as extracellular structure organization and the PI3K-Akt signaling pathway. Kaplan-Meier curves confirmed that high expression of SCARA5, LOXL2, LOXL3, LOXL4 were related to poor survival, whereas high expression of DMBTI and PRSS12 showed the opposite result. SRCR genes promote the development of ESCC through its network and could serve as potential prognostic factors and therapy targets of ESCC.
Insights
Scavenger receptor cysteine-rich (SRCR) proteins are implicated in esophageal squamous cell carcinoma (ESCC). This study identifies key SRCR genes and their network, revealing their potential as prognostic factors and therapeutic targets in ESCC.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Scavenger receptor cysteine-rich (SRCR) proteins, characterized by SRCR domains, are crucial in human diseases.
- The specific roles of SRCR proteins in esophageal squamous cell carcinoma (ESCC) are not fully understood.
Purpose of the Study:
- To elucidate the functions of SRCR proteins in ESCC.
- To identify differentially-expressed SRCR genes and construct their biological network.
- To evaluate the prognostic significance of SRCR genes in ESCC.
Main Methods:
- Sequence alignment and phylogenetic analysis of human SRCR domains.
- Identification of differentially-expressed SRCR genes in ESCC.
- Protein-protein interaction (PPI) network construction and analysis.
- Functional enrichment and survival analyses (Kaplan-Meier curves).
Main Results:
- Variations in conserved cysteines suggest a need for SRCR family reclassification.
- Ten SRCR genes (LGALS3BP, MSR1, CD163, LOXL2, LOXL3, LOXL4, DMBT1, PRSS12, TMPRSS2, SCARA5) showed differential expression in ESCC.
- The SRCR gene network is linked to extracellular structure organization and the PI3K-Akt signaling pathway.
- High expression of SCARA5, LOXL2, LOXL3, LOXL4 correlated with poor survival, while high DMBT1 and PRSS12 expression indicated better survival.
Conclusions:
- SRCR genes and their network significantly influence ESCC development.
- These SRCR genes represent potential prognostic biomarkers for ESCC.
- The SRCR gene network offers potential therapeutic targets for ESCC treatment.
