Clinical Implications of HSC70 Expression in Clear Cell Renal Cell Carcinoma

Purpose: The role of heat shock protein 70 (HSC70) in the progression of clear cell renal cell carcinoma (ccRCC) is unclear. This study explored the effect of the HSC70 on the survival of ccRCC patients.Methods: Immunohistochemical analysis was performed to determine HSC70 expression in samples obtained from 121 ccRCC patients with at least 5 years of follow-up. We also analyzed the association between HSC70 expression and clinicopathological characteristics. Furthermore, the association of overall survival (OS) with HSC70 expression was analyzed using Kaplan-Meier curves. Finally, we used the Oncomine and CCLE databases to determine the effects of HSC70 mRNA expression on ccRCC.Results: HSC70 expression was associated with distant metastasis and death of ccRCC patients. HSC70 was expressed in the nucleus and/or cytoplasm of ccRCC cells. The incidence of distant organ metastasis and death was higher in patients with HSC70 expression than in those without it. Survival analysis revealed that patients with HSC70 expression had significantly shorter OS. Oncomine analyses also showed that the HSC70 mRNA was significantly upregulated in ccRCC tissues.Conclusions: HSC70 expression was related to adverse prognosis, and patients with HSC70 expression had a worse prognosis than those without HSC70 expression. HSC70 may thus serve as a potential therapeutic target for ccRCC.

目的 探讨应用长效α-干扰素联合利巴韦林治疗慢性丙型肝炎(CHC)患者疗效及静息能量消耗和营养状态的变化。方法 2017年4月～2019年4月我院收治的CHC患者48例,采用随机数字表法分为观察组24例和对照组24例,分别给予聚乙二醇干扰素α-2a(peg-IFNα-2a)和利巴韦林治疗或干扰素α-2a(IFNα-2a)联合利巴韦林治疗48 w。测量静息能量消耗(REE)和预测静息能量消耗(pREE),常规检测血清前白蛋白(PA)和白蛋白(ALB)水平,计算体质指数(BMI)。结果 在治疗48 w结束和随访6 m时,观察组完全应答率分别为62.5%和54.2%,显著高于对照组的37.5%和29.2%,差异有统计学意义(P＜0.05);在观察组,用药前REE和pREE分别为(1504.6±481.5)kcal/d和(1432.3±229.3)kcal/d,在治疗结束时显著增加至(1822.1±546.7)kcal/d和(1241.8±208.6)kcal/d,对照组用药前REE和pREE分别为(1505.2±482.1)kcal/d和(1433.5±231.2)kcal/d,在治疗结束时,显著增加至(1824.4±547.6)kcal/d和(1243.1±208.8)kcal/d, 但两组之间REE和pREE变化无显著性差异(P>0.05);治疗前,观察组BMI及血清PA和ALB水平分别为(19.2±2.0)kg/m²、(161.5±45.2)mg/L和(38.4±4.2)g/L,在治疗结束时分别降为(17.1±1.5)kg/m²、(135.8±40.2)mg/L和(34.2±3.2)g/L,治疗前对照组BMI及血清PA和ALB水平分别为(19.3±2.1)kg/m²、(161.3±45.0)mg/L和(38.5±4.4)g/L,在治疗结束时分别降为(17.2±1.5)kg/m²、(136.3±40.2)mg/L和(34.2±3.1)g/L,但两组之间这些指标的变化无显著性差异(P>0.05)。结论 相对于IFNα-2a与利巴韦林联合,应用peg-IFNα-2a与利巴韦林联合治疗CHC患者能够获得更好的治疗效果,但无论何种治疗方案,均增加了能量消耗,降低了体质量和血清白蛋白水平,提示标准方案抗病毒治疗的不良反应还是值得重视的。

Increased expression of GAB1 promotes inflammation and fibrosis in systemic sclerosis

Systemic sclerosis (SSc) is an autoimmune disease mainly characterized by persistent inflammation and fibrosis. The receptor tyrosine kinase (RTK) signal pathway plays an important role in the process of SSc, and Grb2‐associated binding protein (GAB) is crucial in activating RTK signalling. A previous study found elevated levels of GAB1 in bleomycin (BLM)‐induced fibrotic lungs, but the effects of GAB1 in SSc remain unclear. Our aim was to investigate whether GAB1 was dysregulated and its potential role in SSc. Compared with healthy donors, we found GAB1 expression was 1.6‐fold higher in peripheral blood mononuclear cells (PBMC), 2.5‐fold higher in CD4 + T cells, and 2‐fold higher in skin from of SSc patients (P < .01). At the same time, the levels of type one collagen (COLI) were also significantly increased (1.8‐fold higher) in SSc skin. Additionally, BLM‐induced SSc mice showed mRNA levels of Gab1 2‐fold higher than saline‐treated controls, and Gab1 expression correlated positively with collagen content. A further in vitro study showed silencing of GAB1 suppressed inflammatory gene expression in TNF‐α induced fibroblasts. Additionally, GAB1 deficiency prominently inhibited cell proliferation and reduced COLI protein levels in TGF‐β induced fibroblasts. Taken together, these data suggest that GAB1 has a relatively high expression rate in SSc, and knockdown of GAB1 may attenuate SSc by stimulating inflammatory and fibrotic processes.
