67PPARP inhibition enhances cisplatin sensitivity in cervical cancer by modulating β-catenin signaling
ConclusionsOur data provides experimental evidence on the contribution of PARP-1 inhibition in enhancing the cytotoxicity of CDDP in cervical cancer cells. We also present novel findings on the suppression of β-catenin and its downstream signaling components by PARP-1 inhibitor. #: 5μM of CDDP was used both alone and in combination with PJ34; ##: A gradient of CDDP from 0-15μM was used to evaluate the combined effect of PJ34 and CDDP on IC50 value of CDDP. p: *<0.05, **<0.01.

Endothelial Cell-Derived TGF- β Promotes Epithelial-Mesenchymal Transition via CD133 in HBx-Infected Hepatoma Cells
Conclusion: The study indicates that secretory factors like TGF-β from neighboring endothelial cells may enhance expression of CD133 and impart an aggressive EMT phenotype to HBx-infected hepatoma cells in HBV induced HCC. Introduction Hepatocellular Carcinoma (HCC) is one of the most common cancer worldwide, representing approximately 4% of all malignancies (1). It has been estimated that more than 50% of HCC cases in the world are associated with hepatitis B virus (HBV) (2). HBV is a partially double stranded DNA virus belonging to the Hepadnavirus family. The HBV genome is 3.2 kb in size and contains fou...

Identification of spleen tyrosine kinase as a potential therapeutic target for esophageal squamous cell carcinoma using reverse phase protein arrays.
Authors: Barbhuiya MA, Kashyap MK, Puttamallesh VN, Kumar RV, Wu X, Pandey A, Gowda H Abstract The vast majority of esophageal cancers in China, India and Iran are esophageal squamous cell carcinomas (ESCC). A timely diagnosis provides surgical removal as the main therapeutic option for patients with ESCC. Currently, there are no targeted therapies available for ESCC. We carried out reverse phase protein array-based protein expression profiling of seven ESCC-derivedcell lines and a non-neoplastic esophageal epithelial cell line (Het-1A) to identify differentially expressed proteins in ESCC. SYK non-receptortyrosine...

Role of β-catenin in cisplatin resistance, relapse and prognosis of head and neck squamous cell carcinoma
ConclusionFrom our results we conclude that β-catenin may contribute to HNSCC therapy resistance and disease relapse. As such, β-catenin may be explored as a therapeutic target along with conventional therapeutics.
