Abstract To study the roles and association of murine double minute gene 2 (MDM2) and fructose-1,6-biphosphatase (FBP1) in human hepatocellular carcinoma (HCC), growth response of human HCC cells was assessed using proliferation and apoptosis assay. Pro-survival AKT signaling associated proteins (p-AKT, survivin and cleaved caspase 3) were assessed using western blotting. The correlation between MDM2 and FBP1 was assessed using co-immunoprecipitation combined with ubiquitination assay. Our data suggested that low expression of FBP1 was correlated with high levels of MDM2 in HCC cell lines (Huh7 and Hep3B). Overexpression of FBP1 resulted in anti-proliferation, pro-apoptosis, the up-regulation… More >

Abstract Chemotherapy is critical for the treatment of hepatocellular carcinoma (HCC). Despite the proapoptotic effects of corosolic acid (CA) treatment, its underlying mechanism is not completely clear. The aim of this study was to determine the molecular mechanism of CA in HCC treatment. MTT assay was used to determine the IC50 of CA. Immunoprecipitation and immunofluorescence were used to detect the interaction and subcellular localization of Yes-associated protein (YAP) and mouse double minute 2 (MDM2). In addition, in vivo xenotransplantation was performed to assess the effects of CA, YAP, and MDM2 on tumorigenesis. The IC50 of… More >

Abstract Despite therapeutic advances, the effective treatment for relapsed or refractory diffuse large B-cell lymphoma (DLBCL) remains a major clinical challenge. Evasion of apoptosis through upregulating antiapoptotic B-cell lymphoma-2 (BCL-2) family members and p53 inactivation, and abnormal activation of B-cell receptor signaling pathway are two important pathogenic factors for DLBCL. In this study, our aim is to explore a rational combination of BCL-2 inhibitor plus Bruton’s tyrosine kinase (BTK) blockade or p53 activation for treating DLBCL with the above characteristics. We demonstrated that a novel BCL-2 selective inhibitor APG-2575 effectively suppressed DLBCL with BCL-2 high expression… More >

Abstract Lung cancer is the leading cause of deaths due to cancer. Studies suggest an important role of microRNAs (miRNAs) in a variety of cancers, including lung cancer. In the present study, we evaluated the role of miR- 641 in human lung cancer A549 cells. Quantitative RT-PCR and Western blot were used to measure mRNA and protein expression, respectively. Cell viability and cell apoptosis were respectively measured by MTT assay and flow cytometry. In addition, luciferase activity assay was used to identify the target of miR-641. The expression of miR-641 was downregulated in lung cancer tissues More >

Abstract Many diseases including cancer are associated with a disorganised cytoskeleton. The process of characterising how cytoskeletal disorganisation affects the mechanical properties of cells offers the potential to develop new drugs and treatment regimes that may exploit mechanical weakness in cells and tissues. This work investigated the role of actin associated proteins, namely tropomyosin 1 (tpm1p) and mitochondrial distribution and morphology protein 20 (mdm20p), on the mechanical and morphological properties of yeast cells. For the first time it was shown that deletion of both the TPM1 and MDM20 genes resulted in a decrease in Young’s modulus More >
