Deviation from proper muscle development or homeostasis results in various myopathic conditions. Employing genetic as well as chemical intervention, we provide evidence that a tight regulation of Wnt/beta-catenin signaling is essential for muscle fiber growth and maintenance. In zebrafish embryos, gain-of-Wnt/beta-catenin function results in unscheduled muscle progenitor proliferation, leading ...

Zinc finger proteins (ZNF) play important roles in various physiological processes. Here we report that ZNF300, a novel zinc finger protein, identified specifically in humans, promotes tumour development by modulating the NF-κB pathway. Inflammatory factors were found to induce ZNF300 expression in HeLa cell line, and ZNF300 expression further enhanced NF-κB signalling by activating TRAF2 and p...

Mutations in the serine-threonine tumor-suppressor kinase LKB1 are responsible for Peutz-Jeghers syndrome, characterized by hamartomatous proliferation and an increased risk of developing cancer. Mutations in lkb1 have also been identified in sporadic cancers, suggesting a wider role for LKB1 in cancer that is not limited to hamartomatous polyposis syndromes. Here, we show that LKB1 catalytical...

Gemcitabine is a standard chemotherapeutic agent for locally advanced and metastatic pancreatic cancer. However, the chemoresistance of pancreatic cancer is the major barrier to efficient chemotherapy. Here, we reported that BRG1, a chromatin modulator, was exclusively overexpressed in human pancreatic ductal adenocarcinoma tissues. BRG1 knockdown inhibited PANC-1 and MIA PaCa-2 cell growth in ...

Background: Previous studies suggest that human RAD9 (hRad9), encoding a DNA damage checkpoint molecule, which is frequently amplified in epithelial tumor cells of breast, lung, head and neck cancer, participates in regulation of the tumor suppressor p53-dependent transactivation of pro-survival P21WAF1. This study examined the exact mechanism of the hRad9 function, especially through the phosp...

The assignment of weights to attacks in a classical Argumentation Framework allows to compute semantics by taking into account the different importance of each argument. We represent a Weighted Argumentation Framework by a non-binary matrix, and we characterize the basic extensions (such as w-admissible, wstable, w-complete) by analysing sub-blocks of this matrix. Also, we show how to reduce th...

Storage space, loss of documents, misfiled and misplaced documents, and document retrieval are just a few of the problems of processing large volumes of paper. High storage costs, lost productivity, personnel costs, and poor responsiveness are some of the results. Until recently, technology could not provide a Cost-effective method for reducing this paper flow. IBM designed its midrange ImagePl...
