Does calmodulin regulate the bicarbonate permeability of ANO1/TMEM16A or not? [PDF]

Journal of General Physiology, 2014
The role of calmodulin in the activation of Ca2+-activated Cl− channels (CaCCs) has been an important topic over the past three decades of CaCC research. Recently, the discovery of ANO1/TMEM16 as a component of CaCC raised the question of whether calmodulin modulates ANO1 activity ([Tian et al.,

Update on cellular expression and function of ANO1 channels in urethral smooth muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Activation of ANO1 channels and resulting Cl− efflux are suggested to modulate urethral smooth muscle contractility by enhancing Ca2+ influx via voltage‐dependent Ca2+ entry and resulting contraction in urethral smooth muscle cells.

Detection of ANO1 mRNA in PBMCs is a promising method for GISTs diagnosis [PDF]

Scientific Reports, 2019
AbstractANO1 is a calcium-activated chloride channel protein that has been used to diagnose GISTs after tissue biopsy. Recently, ANO1 mRNA amplification in the blood has received considerable attention as a useful method for the diagnosis of GISTs. The aim of this study was to evaluate the diagnostic ability of ANO1 mRNA in distinguishing GIST patients

Acidic amino acids in the first intracellular loop contribute to voltage- and calcium- dependent gating of anoctamin1/TMEM16A. [PDF]

PLoS ONE, 2014
Anoctamin1 (Ano1, or TMEM16A) is a Ca2+-activated chloride channel that is gated by both voltage and Ca2+. We have previously identified that the first intracellular loop that contains a high density of acidic residues mediates voltage- and calcium ...

Activation of the Ano1 (TMEM16A) chloride channel by calcium is not mediated by calmodulin [PDF]

Journal of General Physiology, 2014
The Ca2+-activated Cl channel anoctamin-1 (Ano1; Tmem16A) plays a variety of physiological roles, including epithelial fluid secretion. Ano1 is activated by increases in intracellular Ca2+, but there is uncertainty whether Ca2+ binds directly to Ano1 or whether phosphorylation or additional Ca2+-binding subunits like calmodulin (CaM) are required.

Presynaptic Localization and Possible Function of Calcium-Activated Chloride Channel Anoctamin 1 in the Mammalian Retina. [PDF]

PLoS ONE, 2013
Calcium (Ca(2+))-activated chloride (Cl(-)) channels (CaCCs) play a role in the modulation of action potentials and synaptic responses in the somatodendritic regions of central neurons. In the vertebrate retina, large Ca(2+)-activated Cl(-) currents (ICl(

ANO1 taking center stage: Blood pressure regulation in SHRs [PDF]

Journal of Molecular and Cellular Cardiology, 2015
Calcium-activated chloride channels (CaCCs) were first described in 1981, when injection of Ca2+ or Ca2+ ionophore into Rana pipiens eggs initiated a transient shift to positive membrane potentials in a chloride-dependent manner [1]. Major biophysical features of CaCCs include: 1) ability of being activated by cytosolic Ca2+ in the submicromolar range;

Molecular Mechanisms of Electric Signals Generated at Corneal Wounds

The FASEB Journal, Volume 40, Issue 16, 31 August 2026.
Corneal injury triggers cell signaling (including calcium waves) leading to ion channel up‐regulation, increased ion pumping, and enhanced wound electric signals which stimulate wound healing. ABSTRACT Over 150 years ago, it was demonstrated that wounds produce electric fields and currents.

Multi‐Omics Profiling Reveals Immunomodulatory and Pro‐Regenerative Effects of a Graphene Oxide–Collagen Scaffold in Massive Rotator Cuff Tears

Advanced Science, Volume 13, Issue 44, 7 August 2026.
A graphene oxide/collagen scaffold is developed for chronic massive rotator cuff tear repair. The scaffold improves compressive stability, supports reparative mesenchymal differentiation, and modulates the immune microenvironment. In chronic MRCT models, it reduces muscle degeneration, enhances tendon–bone regeneration, and improves functional recovery,
