The prevalence of Hepatocellular carcinoma (HCC) has been identified world-wide. Plethora of factors including chronic infection of HBV/HCV has been characterized for the development of HCC. Although the onset and progression of HCC has been linked with awry of various signaling pathways but precise mechanism, still lies under the multitude layers of curiosity. HBV is spreading with insane speed throughout the world and has been found a main culprit in HCC development after regulating the several cellular pathways including Wnt/β-catenin, Raf/MAPK, Akt and affecting cell multiplication to genomic instability. The role of Wnt/FZD/β-catenin signaling pathway is centralized in liver functions and its anomalous activation leads to HCC development. β-catenin mainly plays a pivotal role in canonical pathway of the system. Altered mainly overexpression of β-catenin along its nuclear localization tunes the aberrations in liver functions and set disease progression. In the development of HCC, modulation of Wnt/FZD/β-catenin signaling pathway by HBV has been established. As HBV infects the cell it affects the miRNAs, the master regulators of cell. Previous studies showed the connection between HBV and cellular miRNAs. In the present review, we unveiled how HBV is deciphering the cellular miRNAs like miR-26a, miR-15a, miR-16-1, miR-148a, miR-132, miR-122, miR-34a, miR-21, miR-29a, miR-222 and miR-199a/b-3p to modulate the Wnt/FZD/β-catenin signaling pathway and develop HCC. These HBV mediated miRNAs may prove future therapeutic options to treat HBV-Wnt/FZD/β-catenin associated HCC.
肝细胞癌(HCC)的患病率已在全球范围内得到确认。包括HBV/HCV慢性感染在内的众多因素已被确定为HCC发生发展的特征。尽管HCC的发生和进展与各种信号通路紊乱有关,但其确切机制仍充满诸多未知。HBV正在以惊人的速度在全球传播,并且已被发现是HCC发生发展的主要元凶,它通过调节包括Wnt/β-连环蛋白、Raf/MAPK、Akt等多种细胞通路,并影响细胞增殖直至基因组不稳定。Wnt/FZD/β-连环蛋白信号通路的作用集中在肝脏功能方面,其异常激活会导致HCC的发生。β-连环蛋白主要在该系统的经典通路中起关键作用。β-连环蛋白的主要改变是其过表达以及核定位,这会调节肝脏功能异常并推动疾病进展。在HCC的发生发展过程中,HBV对Wnt/FZD/β-连环蛋白信号通路的调节作用已得到证实。当HBV感染细胞时,它会影响细胞的主要调节因子——微小RNA(miRNA)。先前的研究表明了HBV与细胞miRNA之间的联系。在本综述中,我们揭示了HBV如何解读细胞miRNA,如miR-26a、miR-15a、miR-16-1、miR-148a、miR-132、miR-1,22、miR-34a、miR-21、miR-29a、miR-222和miR-199a/b-3p,以调节Wnt/FZD/β-连环蛋白信号通路并引发HCC。这些由HBV介导的miRNA可能成为治疗与HBV-Wnt/FZD/β-连环蛋白相关的HCC的未来治疗选择。
