Fibrodysplasia ossificans progressiva (FOP, MIM #135100) is a rare genetic disorder of heterotopic endochondral ossification, resulting in transformation of soft tissue into episodic bone formation. Currently, no effective treatment for FOP has been established. The causative heterozygous genetic mutations have been identified in either the intracellular glycine-serine-rich (GS) domain or kinase domain of ALK2 Read More

Background: Calreticulin is a Ca2+-binding chaperone in the endoplasmic reticulum (ER) which is crucial to the correct embryological development of the heart in mice. Altered expression levels in the adult were correlated with several cardiac pathologies such as cardiac hypertrophy and dilated cardiomyopathy. Aim: In this review, we aim to describe the role of calreticulin in the embryological development of the heart in mice an Read More

To sustain tumor growth, the cancer cells need to adapt to low levels of oxygen (i.e., hypoxia) in the tumor tissue and to the tumor-associated acidic microenvironment. In this phenomenon, the activation of the sodium/proton exchanger 1 (NHE1) at the plasma membrane and the hypoxia-inducible factor (HIF) are critical for the control of the intracellular pH (pHi) and for hypoxia adaptation, respectively. Interestingly, both Read More

Vagus nerve stimulation (VNS) has been widely used to treat different neurological disorders, especially epilepsy. Accumulating evidence also suggests its potential application in antidepressive therapy, given that VNS has been confirmed by several clinical trials to exert long-term effects on mitigating depression and reducing the risk of relapse in depressed patients. Likewise, VNS has also proven to ameliorate the behavi Read More

The family of fibroblast growth factor (FGFs) and their receptors (FGFRs) regulates vital roles in many biological processes affecting cell proliferation, migration, differentiation and survival. Deregulation of the FGF/FGFR signaling pathway in cancers has been better understood and the main molecular mechanisms responsible for the activation of this pathway are gene mutations, gene fusions and gene amplification. DN Read More

Jade-1 is originally identified by the yeast two-hybrid system as a protein partner of von Hippel-Lindau (pVHL) tumor suppressor, a well-known renal tumor suppressor. In cellular signaling pathways, many upstream Jade-1 regulators, such as pVHL, CK1α, PC1, and NPHP4, can control its activity by stabilization, phosphorylation, and nuclear translocation. Numerous downstream effectors, including β-catenin, AKT, p21, and Bcl-2, are Read More

Objective: We investigated mechanisms of colorectal cancer (CRC) chemoresistance to first-line chemotherapy (capecitabine plus oxaliplatin (XELOX)) and identified two putative chemoresistant microRNAs, miR-1914* and -1915, that are downregulated in plasma samples from patients with chemoresistant CRC. Methods: A number of plasma samples from CRC patients were analyzed for the levels of miR-1914* and - 191 Read More

Pancreatic ductal adenocarcinoma (PDAC) is one of the most potent and perilous diseases known, with a median survival rate of 3-5 months due to the combination of only advanced stage diagnosis and ineffective therapeutic options. Metformin (1,1-Dimethylbiguanide hydrochloride), the leading drug used for type 2 diabetes mellitus, emerges as a potential therapy for PDAC and other human cancers. Metformin exerts its Read More

Parvalbumin (PV)-positive interneurons in the hippocampus play a critical role in animal memory, such as spatial working memory. However, how PV-positive interneurons in the subregions of the hippocampus affect animal behaviors remains poorly defined. Here, we achieved specific and reversible activation of PV-positive interneurons using designer receptors exclusively activated by designer drugs (DREADD) technology. Read More
