Abstract

Purpose: Heat shock protein A4 (HSPA4) is associated with a variety of human diseases. However, its function in cutaneous malignant melanoma (CMM) remains uncertain.

Patients and methods: The gene and protein expression level of HSPA4 in CMM was investigated with public databases. Cell Counting Kit-8 (CCK8) assay was performed to assess the effect of HSPA4 on the proliferation of melanoma cells. Then, the diagnostic and prognostic value of HSPA4 in CMM were analyzed. Gene variations and methylation levels, and the correlation between HSPA4 expression and immune cell infiltration were evaluated, followed by the construction of HSPA4 related protein-protein interaction networks and functional enrichment analysis.

Results: The mRNA and protein expression level of HSPA4 was significantly higher in CMM. Knocking down HSPA4 in A-375 cell line could inhibit tumor cell growth. The receiver operating characteristic (ROC) curve analysis confirmed the diagnostic value of HSPA4. Survival analysis showed that high expression of HSPA4 was associated with poor prognosis. HSPA4 gene alterations were observed in 3% of CMM patients. Five CpG sites are associated with the prognosis of CMM. HSPA4 is negatively correlated with most immune cells in CMM. The protein interaction network shows that HSPA4 is closely related to proteins such as DnaJ heat shock protein family (Hsp40) member B1 (DNAJB1) and DnaJ heat shock protein family (Hsp40) member B6 (DNAJB6), and the expression of DNAJB1 is positively correlated with HSPA4. Functional enrichment analysis indicated that HSPA4 may be associated with immune suppression and immune escape within the tumor microenvironment of CMM.

Conclusion: HSPA4 may participate in the regulation of tumor development and microenvironment, which may be a potential diagnostic and prognostic marker of CMM.

期刊介绍: Clinical, Cosmetic and Investigational Dermatology is an international, peer-reviewed, open access journal that focuses on the latest clinical and experimental research in all aspects of skin disease and cosmetic interventions. Normal and pathological processes in skin development and aging, their modification and treatment, as well as basic research into histology of dermal and dermal structures that provide clinical insights and potential treatment options are key topics for the journal. Patient satisfaction, preference, quality of life, compliance, persistence and their role in developing new management options to optimize outcomes for target conditions constitute major areas of interest. The journal is characterized by the rapid reporting of clinical studies, reviews and original research in skin research and skin care. All areas of dermatology will be covered; contributions will be welcomed from all clinicians and basic science researchers globally.
