HSPA5


Also found in: Acronyms.

HSPA5

A gene on chromosome 9q33.3 that encodes a member of the heat shock 70 (HSP70) family which is localised in the lumen of the endoplasmic reticulum, where it is involved in protein folding and assembly. 

Molecular pathology
HSPA5 is an autoantigen implicated in the pathogenesis of rheumatoid arthritis.

These genes were divided into two networks: one network was interlocking histone genes clusters and another network consisted of 39 genes, which included several important node genes such as EGFR, FOS, HSPA5, TLR4, and MMP9 (Figure 3).
In summary, aging and epigenetic regulation dominate bladder carcinogenesis through CALR, PDIA3, DNAJB11, HSPA5, RPN1, HSP90B1, KPNA2, ECT2, and PSMD11 and through COPS5, PSMD8, RNF126, CALR, PDIA3, HSP90B1, PSMD12, PSMD11, JUN, HN1, and ENO1, respectively.
The design of a multiple drug combination for treating stage 1 bladder cancer depends on a strategy of inhibiting the highly expressed genes ADRM1, COPS5, PSMD8, SUMO2, CALR, PDIA3, DNAJB11, HSPA5, RPN1, CUL1, HSP90B1, KPNA2, PSMD12, ECT2, TK1, TUBA1C, HN1, and ENO1; activating the suppressed genes UBC, JUN, RARRES3, and FOS; and suppressing the drug's effect on the nondifferentially expressed genes BAG6, HUWE1, PAAF1, PSMD10, FAF2, PCYT1A, and PSMD10.
The design of a multiple drug combination for treating stage 4 bladder cancer depends on a strategy of inhibiting the highly expressed genes ADRM1, COPS5, PSMD8, SUMO2, RNF126, CALR, PDIA3, DNAJB11, HSPA5, RPN1, HSP90AA1, HSPA1B, METTL23, RARRES3, KPNA2, PSMD12, ECT2, JUN, TK1, TUBA1C, HN1, and ENO1; activating the suppressed genes BCL3, FOS, UBC, and GTF2A1; and suppressing the drug's effect on the nondifferentially expressed genes, which are the same as those in stage 1 bladder cancer.
The major factors, including downregulated miR12, the aging-related proteins, HSP90B1, CALR, HSPA5, PDIA3, RPN1, and ECT2, the smoking-related proteins, HUWE1, HSPA5, and ECT2, and the epigenetic regulation of ENO1, HSP90B1, CALR, and PDIA3, lead to the progression from normal bladder cells to stage 1 bladder cancer cells through the SUP and ER signaling pathways.
This is the first study to suggest a panel of HSPs (Dnaja 1, Dnajb4,Hsp90aa 1, Hsp90ab 1, Hspa 1 b, Hspa5, and Hspa8) as effector genes in response to [O.sub.3] -induced TLR4 signaling.
The epidermal growth factor receptor (EGFR), tumor protein p53 (TP53), and heat shock protein A member 5 (HSPA5) were the top three hubs, indicating highest connectivity and greatest capacity to regulate the interaction network (Figures 4 and 5).
Quantitative PCR was performed to confirm expression changes of proteins with highest connectivity, including EGFR, TP53, HSPA5, excision repair cross-complementation group 1 (ERCC1), and X-ray repair cross complementing 1 (XRCC1), in several prostate cell lines.
HSPA5 is also overexpressed in some cancers, including breast, hepatocellular, and lung cancer [23-25].
