Anoctamin 1 is Apically Expressed on Thyroid Follicular Cells and Contributes to ATP- and Calcium-Activated Iodide Efflux

Cellular Physiology and Biochemistry, 2014
Background/Aims: Iodide efflux from thyroid cells into the follicular lumen is essential for the synthesis of thyroid hormones, however, the pathways mediating this transport have only been partially identified.

Neuronal and ion channel mechanisms of noxious heat sensing in mammals: A puzzle of sensory physiology and pharmacology

British Journal of Pharmacology, EarlyView.
Transient receptor potential vanilloid 1 (TRPV1) was the first noxious heat‐sensitive channel discovered. In rodents, its role is robust in the heat response of the cell body of polymodal nociceptors, but surprisingly small in that of the peripheral terminals in the skin.

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

Oral Diseases, EarlyView.
ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...

TMEM16A channel signalling microdomains in the regulation of vascular function

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

TMEM16A/ANO1 Inhibits Apoptosis Via Downregulation of Bim Expression [PDF]

Clinical Cancer Research, 2017
Abstract Purpose: TMEM16A is a calcium-activated chloride channel that is amplified in a variety of cancers, including 30% of head and neck squamous cell carcinomas (HNSCCs), raising the possibility of an anti-apoptotic role in malignant cells. This study investigated this using a multimodal, translational investigation.

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

The Journal of Physiology, EarlyView.
Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

TMEM16A chloride channels in the female reproductive tract and their role in normal and dysfunctional pregnancy and labour

The Journal of Physiology, EarlyView.
Abstract figure legend TMEM16A plays a pivotal role in setting the duration of the action potential plateau in human uterine smooth muscle. An increase in TMEM16A expression in labour underpins a lengthening of the plateau and this provides time for the contraction to become larger and longer, important for timely successful labour.

Novel volume‐electron microscopic ultrastructural analysis of gastrointestinal excitability associated with calcium–activated chloride channels

The Journal of Physiology, EarlyView.
Abstract figure legend Immunohistochemistry, electrophysiology and pharmacology are useful tools for understanding protein and channel expression and physiological reactions of calcium‐activated chloride channels (CaCCs). Conventional transmission electron microscopy has provided useful 2‐D information on organelle arrangement, localization and ...
