Hedgehog pathway dysregulation contributes to the pathogenesis of human gastrointestinal stromal tumors via GLI-mediated activation of KIT expression. [PDF]
, 2016 Gastrointestinal stromal tumors (GIST) arise within the interstitial cell of Cajal (ICC) lineage due to activating KIT/PDGFRA mutations. Both ICC and GIST possess primary cilia (PC), which coordinate PDGFRA and Hedgehog signaling, regulators of ...

Paneth Cell Secretion in vivo Requires Expression of Tmem16a and Tmem16f
Gastro Hep Advances, 2022 Background and Aims: Paneth cells play a central role in intestinal innate immune response. These cells are localized at the base of small intestinal crypts of Lieberkuhn.

ER localized bestrophin1 activates Ca2+ dependent ion channels TMEM16A and SK4 [PDF]
, 2009 Bestrophins form Ca2+ activated Cl- channels and regulate intercellular Ca2+ signaling1. We demonstrate that bestrophin 1 is localized in the endoplasmic reticulum (ER), where it physically interacts with stromal interacting molecule 1 (Stim1), the ER ...

Disulfide Bond Connectivity and Oligomeric State of Anoctamin-1 [PDF]
Biophysical Journal, 2013 TMEM16A(a)/anoctamin-1 (Ano1) has been identified as a Ca-activated chloride channel. Using blue native PAGE, SDS-PAGE and chemical cross-linking, we have shown that the mouse Ano1 channel (mAno1) shares an obligate homodimeric architecture with the hCLC-1 channel (Fallah et al. Molecular & Cellular Proteomics 10.1074/mcp. M110.004697, 2011).

MicroRNA-9 downregulates the ANO1 chloride channel and contributes to cystic fibrosis lung pathology
Nature Communications, 2017 Downregulation of the anoctamin 1 calcium channel in airway epithelial cells contributes to pathology in cystic fibrosis. Here the authors show that microRNA-9 targets anoctamin 1 and that inhibiting this interaction improves mucus dynamics in mouse ...

TRPC1 regulates calcium-activated chloride channels in salivary gland cells [PDF]
, 2015 Calcium-activated chloride channel (CaCC) plays an important role in modulating epithelial secretion. It has been suggested that in salivary tissues, sustained fluid secretion is dependent on Ca2+ influx that activates ion channels such as CaCC to ...

Ca2+ tunnelling through the ER lumen as a mechanism for delivering Ca2+ entering via store-operated Ca2+ channels to specific target sites [PDF]
, 2017 Ca2+ signaling is perhaps the most universal and versatile mechanism regulating a wide range of cellular processes. Because of the many different calcium-binding proteins distributed throughout cells, signaling precision requires localized rises in the ...
