Introduction

Interacts with TGF-beta receptor type-1 (TGFBR1) and inhibits dissociation of activated SMAD2 from TGFBR1, impeding its nuclear accumulation and resulting in impaired TGF-beta signaling. May also affect FOXO, Hippo and Wnt signaling.

Molecular mechanism of WWP1‐mediated ubiquitination modification affecting proliferation and invasion/migration of liver cancer cells

Article

Author: Wang, Wei ; Wu, Biao ; Zhang, Chao

AbstractLiver cancer is the most prevalent fatal malignancy across the globe. The present study aims to explore the molecular mechanism of E3 ligase WWP1 in liver cancer cell proliferation and invasion/migration. RT‐qPCR and Western blot were performed to detect WWP1, KLF14, and VEPH1 expressions in liver cancer cell lines. Furthermore, WWP1 expression was silenced in cells, followed by the detection of cell viability, proliferation, and invasion/migration by CCK‐8, colony formation, and Transwell assays, respectively. ChIP was used to analyze the binding relationship between WWP1 and KLF14. We measured the KLF14 ubiquitination level and KLF14 enrichment on the VEPH1 promoter after MG132 treatment. Dual‐luciferase reporter assay was used to validate the binding relationship between KLF14 and VEPH1. Consequently, WWP1 was highly expressed in liver cancer cells; WWP1 silencing reduced the proliferation and invasion/migration of liver cancer cells. Mechanistically, WWP1 promoted KLF14 ubiquitination degradation; KLF14 was enriched on the VEPH1 promoter to promote its transcription and protein expression. Inhibiting KLF14 or VEPH1 partially minimized the inhibitory effect of WWP1 silencing on liver cancer cell proliferation and invasion/migration. In summary, WWP1 degrades KLF14 through ubiquitination, hence repressing VEPH1 expression and accelerating proliferation and invasion/migration of liver cancer cells.

Hypomethylation of Wnt Signaling Regulator Genes in Developmental Language Disorder

Article

Author: Thomas, Sanjeev V ; Iype, Mary ; James, Jesmy ; Anitha, Ayyappan ; Melempatt, Nisha

Background: Developmental language disorder (DLD) is a neurodevelopmental disorder. Considering the pivotal role of epigenetics in neurodevelopment, we examined any altered DNA methylation between DLD and control subjects. Materials & methods: We looked into genome-wide methylation differences between DLD and control groups. The findings were validated by quantitative PCR (qPCR). Results: In the DLD group, differential methylation of CpG sites was observed in the Wnt signaling regulator genes APCDD1, AMOTL1, LRP5, MARK2, TMEM64, TRABD2B, VEPH1 and WNT2B. Hypomethylation of APCDD1, LRP5 and WNT2B was confirmed by qPCR. Conclusion: This is the first report associating Wnt signaling with DLD. The findings are relevant in the light of the essential role of Wnt in myelination, and of the altered myelination in DLD.

BACKGROUNDVentricular zone-expressed PH domain-containing protein homologue 1 (VEPH1) is a recently discovered intracellular adaptor protein that plays an important role in human development. It has been reported that VEPH1 is closely related to the process of cellular malignancy, but its role in gastric cancer has not been elucidated. This study investigated the expression and function of VEPH1 in human gastric cancer (GC).METHODSWe performed qRT‒PCR, Western blotting, and immunostaining assays in GC tissue samples to evaluate VEPH1 expression. Functional experiments were used to measure the malignancy of GC cells. A subcutaneous tumorigenesis model and peritoneal graft tumour model were established in BALB/c mice to determine tumour growth and metastasis in vivo.RESULTSVEPH1 expression is decreased in GC and correlates with the overall survival rates of GC patients. VEPH1 inhibits GC cell proliferation, migration, and invasion in vitro and suppresses tumour growth and metastasis in vivo. VEPH1 regulates the function of GC cells by inhibiting the Hippo-YAP signalling pathway, and YAP/TAZ inhibitor-1 treatment reverses the VEPH1 knockdown-mediated increase in the proliferation, migration and invasion of GC cells in vitro. Loss of VEPH1 is associated with increased YAP activity and accelerated epithelial-mesenchymal transition (EMT) in GC.CONCLUSIONVEPH1 inhibited GC cell proliferation, migration, and invasion in vitro and in vivo and exerted its antitumour effects by inhibiting the Hippo-YAP signalling pathway and EMT process in GC.
