BACKGROUND: Interferon-α (IFN-α) is an adjuvant to chemotherapy and radiotherapy for hepatocellular carcinoma (HCC), but some HCC patients do not respond to treatment with IFN-α. METHODS: We performed loss-of-function and gain-of-function experiments to examine the role of ISG15 in the IFN-α sensitivity of LH86, HLCZ01, SMMC7721, and Huh7 cell lines and tumor samples. RESULTS: The overexpression of ISG15 reduced apoptosis in Huh7 and LH86 cells in the presence of IFN-α, whereas the shRNA-mediated knock down of ISG15 expression increased apoptosis in both Huh7 and LH86 cells...

Neoadjuvant chemotherapy (NCT) is the standard treatment for locally advanced breast cancer (LABC). Pathological complete response (pCR) is commonly used as a valid predictor of NCT long-term outcomes. Blood-based tumor biomarkers have the potential to predict response to NCT at early stage non-invasively. We believed plasma CCL5 could be a potential marker to predict NCT of LABC. Its efficiency and possible mechanism was studied in this work. Human Cytokine Antibody Microarray was applied to screen different cytokine concentration in plasma between low histological regression (Low-R) and high histological regression (High-R) patients...

Bing Chen, Ya Li, Yuting He, Chen Xue, Feng Xu
Accumulating evidence suggests that long non-coding RNAs (lncRNAs) have important regulatory functions in gallbladder cancer (GBC) tumorigenesis and can serve as potential novel markers and/or targets for GBC. In this review, we critically discuss the emerging alteration of lncRNAs in GBC, the lncRNAs induced epigenetic regulation, the interaction of lncRNAs with microRNAs and lncRNAs effects on tumor-related signaling pathways. Additionally, contributions of lncRNAs in epithelial-mesenchymal transition process and energy metabolism reprogramming in GBC are also addressed...

Cancer is the most important cause of death worldwide, and early cancer detection is the most fundamental factor for efficacy of treatment, prognosis, and increasing survival rate. Over the years great effort has been devoted to discovering and testing new biomarkers that can improve its diagnosis, especially at an early stage. Here we report the potential usefulness of new, easily applicable, non-invasive and relatively low-cost clinical biomarkers, based on abnormalities of oral mucosa spectral reflectance and fractal geometry of the vascular networks in several different tissues, for identification of hereditary non-polyposis colorectal cancer carriers as well for detection of other tumors, even at an early stage...

BACKGROUND: Sensitive and specific biomarkers of Pancreatic Ductal Adenocarcinoma (PDAC) are desperately needed to allow early diagnosis and improve patient's survival. Ezrin autoantibodies were recently described as present in 93% of PDAC patients and 40% of healthy subjects who later developed PDAC. However, another prospective study failed to replicate these findings. Both studies were based on the use of a solid phase ELISA immunoassay. OBJECTIVE: We aimed at re-evaluating the usefulness of Ezrin autoantibodies as PDAC biomarkers using the Luciferase Immuno Precipitation System (LIPS), an alternative immunoassay format that found successful application for the measurement of autoantibodies against pancreatic autoantigens...
