摘要
背景:Prohibitin(PHB)在进化上显然是保守的,在不同的细胞区室中无处不在地表达具有多效功能的蛋白。然而,这些蛋白质在不同细胞,组织和各种疾病中的调节和功能是不同的,这些蛋白质在心脏病,肾脏疾病,肺病,克罗恩氏病和溃疡性结肠炎中表达减少,但是这种蛋白质在多种癌症中高度表达。这种蛋白质在不同亚细胞定位或不同细胞或组织中在不同的条件下(疾病或正常的)在分子水平上起作用的机制仍然知之甚少。有几项研究报告了解和解释PHB在PHB被发现通过其作用的卵巢,肺,胃,甲状腺,肝脏,血液,前列腺,胃,食道,神经胶质瘤,乳房,膀胱等疾病和/或癌症中的作用作为癌基因,抑癌基因,抗氧化剂,抗细胞凋亡,血管生成,自噬等机制 目的:这篇综述特别关注PHB蛋白在心血管健康和疾病中的功能作用和调控机制及其相关意义。分析了涉及PHB功能及其调控的各种分子途径。 结论:PHB正在迅速成为心血管信号转导的关键靶分子。在多种分子途径中描绘心血管疾病的CVD和机制的进展对于确定PHB靶向治疗何时和如何可行是至关重要的。在这方面,针对PHB的新疗法可能最好在将来与CVD的分子谱分析一起应用于疾病诊断和预后的临床分层。

摘要: Background: Prohibitin (PHB) is overtly conserved evolutionarily and ubiquitously expressed protein with pleiotropic functions in diverse cellular compartments. However, regulation and function of these proteins in different cells, tissues and in various diseases is different as evidenced by expression of these proteins which is found to be reduced in heart diseases, kidney diseases, lung disease, Crohn's disease and ulcerative colitis but this protein is highly expressed in diverse cancers. The mechanism by which this protein acts at the molecular level in different subcellular localizations or in different cells or tissues in different conditions (diseases or normal) has remained poorly understood. There are several studies reported to understand and decipher PHB's role in diseases and/or cancers of ovary, lung, stomach, thyroid, liver, blood, prostrate, gastric, esophagus, glioma, breast, bladder etc. where PHB is shown to act through mechanisms by acting as oncogene, tumor suppressor, antioxidant, antiapoptotic, in angiogenesis, autophagy etc.
Objective: This review specifically gives attention to the functional role and regulatory mechanism of PHB proteins in cardiovascular health and diseases and its associated implications. Various molecular pathways involved in PHB function and its regulation are analyzed.
Conclusion: PHB is rapidly emerging as a critical target molecule for cardiovascular signaling. Progress in delineating CVD and mechanisms of PHB in diverse molecular pathways is essential for determining when and how PHB targeted therapy might be feasible. In this regard, new therapies targeting PHB may best be applied in the future together with molecular profiling of CVD for clinical stratification of disease diagnosis and prognosis.
