Background and purpose
Mibefradil (Mib), a T‐type Ca2+ channel blocker, has been investigated for treating solid tumours. However, its underlying mechanisms are still unclear. Here we aimed to investigate the pharmacological aspect of Mib on ORAI st...

Nature communications, 8(1), Article 1920. https://doi.org/10.1038/s41467-017-02094-y

Impaired albumin reabsorption by proximal tubular epithelial cells (PTECs) has been highlighted in diabetic nephropathy (DN), but little is known about the underlying molecular mechanisms. Here we find that ORAI1-3, are preferentially expressed in PT... Read More about ORAI channels are critical for receptor-mediated endocytosis of albumin.

The ryanodine receptor agonist 4-chloro-3-ethylphenol blocks ORAI store-operated channels: 4-Chloro-3-ethylphenol inhibits ORAI channels (2014)
Journal Article
Zeng, B., Chen, G.-L., Daskoulidou, N., & Xu, S.-Z. (2014). The ryanodine receptor agonist 4-chloro-3-ethylphenol blocks ORAI store-operated channels: 4-Chloro-3-ethylphenol inhibits ORAI channels. British Journal of Pharmacology, 171(5), 1250-1259. https://doi.org/10.1111/bph.12528

Background
Depletion of the Ca2+ store by ryanodine receptor (RyR) agonists induces store‐operated Ca2+ entry (SOCE). 4‐Chloro‐3‐ethylphenol (4‐CEP) and 4‐chloro‐m‐cresol (4‐CmC) are RyR agonists commonly used as research tools and diagnostic reagen...

Store-independent pathways for cytosolic STIM1 clustering in the regulation of store-operated Ca2+ influx (2012)
Journal Article
Zeng, B., Chen, G.-L., & Xu, S. Z. (2012). Store-independent pathways for cytosolic STIM1 clustering in the regulation of store-operated Ca2+ influx. Biochemical Pharmacology, 84(8), 1024-1035. https://doi.org/10.1016/j.bcp.2012.07.013

STIM1 is a Ca 2+ sensing molecule. Once the Ca 2+ stores are depleted, STIM1 moves towards the plasma membrane (PM) (translocation), forms puncta (clustering), and triggers store-operated Ca 2+ entry (SOCE). Although this process has been regarded as... Read More about Store-independent pathways for cytosolic STIM1 clustering in the regulation of store-operated Ca2+ influx.
