Preventing β-cell loss and diabetes with calcium channel blockers

G Xu, J Chen, G Jing, A Shalev - Diabetes, 2012 - Am Diabetes Assoc
Although loss of functional β-cell mass is a hallmark of diabetes, no treatment approaches
that halt this process are currently available. We recently identified thioredoxin-interacting …

[HTML][HTML] Exploratory study reveals far reaching systemic and cellular effects of verapamil treatment in subjects with type 1 diabetes

G Xu, TD Grimes, TB Grayson, J Chen… - Nature …, 2022 - nature.com
Currently, no oral medications are available for type 1 diabetes (T1D). While our recent
randomized placebo-controlled T1D trial revealed that oral verapamil had short-term beneficial …

Verapamil and beta cell function in adults with recent-onset type 1 diabetes

F Ovalle, T Grimes, G Xu, AJ Patel, TB Grayson… - Nature medicine, 2018 - nature.com
Pancreatic beta cell loss is a key factor in the pathogenesis of type 1 diabetes (T1D), but
therapies to halt this process are lacking. We previously reported that the approved …

[PDF][PDF] Identification of an anti-diabetic, orally available small molecule that regulates TXNIP expression and glucagon action

LA Thielen, J Chen, G Jing, O Moukha-Chafiq, G Xu… - Cell metabolism, 2020 - cell.com
Diabetes is characterized by hyperglycemia, loss of functional islet beta cell mass, deficiency
of glucose-lowering insulin, and persistent alpha cell secretion of gluconeogenic glucagon. …

Thioredoxin-interacting protein regulates insulin transcription through microRNA-204

G Xu, J Chen, G Jing, A Shalev - Nature medicine, 2013 - nature.com
Beta-cell dysfunction and impaired insulin production are hallmarks of diabetes 1, but despite
the growing diabetes epidemic, the molecular mechanisms underlying this disease have …

Deletion of Gdf15 Reduces ER Stress-induced Beta-cell Apoptosis and Diabetes

G Xu, J Chen, SH Jo, TB Grayson… - …, 2022 - academic.oup.com
Endoplasmic reticulum (ER) stress contributes to pancreatic beta-cell apoptosis in diabetes,
but the factors involved are still not fully elucidated. Growth differentiation factor 15 (GDF15) …

[HTML][HTML] MicroRNA-200 is induced by thioredoxin-interacting protein and regulates Zeb1 protein signaling and beta cell apoptosis

SR Filios, G Xu, J Chen, K Hong, G Jing… - Journal of Biological …, 2014 - ASBMB
Small noncoding microRNAs have emerged as important regulators of cellular processes, but
their role in pancreatic beta cells has only started to be elucidated. Loss of pancreatic beta …

miR-204 controls glucagon-like peptide 1 receptor expression and agonist function

SH Jo, J Chen, G Xu, TB Grayson, LA Thielen… - Diabetes, 2018 - Am Diabetes Assoc
Glucagon-like peptide 1 receptor (GLP1R) agonists are widely used to treat diabetes. However,
their function is dependent on adequate GLP1R expression, which is downregulated in …

[HTML][HTML] FOXO1 competes with carbohydrate response element-binding protein (ChREBP) and inhibits thioredoxin-interacting protein (TXNIP) transcription in …

C Kibbe, J Chen, G Xu, G Jing, A Shalev - Journal of Biological Chemistry, 2013 - ASBMB
Thioredoxin-interacting protein (TXNIP) has emerged as an important factor in pancreatic
beta cell biology, and tight regulation of TXNIP levels is necessary for beta cell survival. …

[HTML][HTML] Cytokines regulate β-cell thioredoxin-interacting protein (TXNIP) via distinct mechanisms and pathways

K Hong, G Xu, TB Grayson, A Shalev - Journal of Biological Chemistry, 2016 - ASBMB
Thioredoxin-interacting protein (TXNIP) is a key regulator of diabetic β-cell apoptosis and
dysfunction, and TXNIP inhibition prevents diabetes in mouse models of type 1 and type 2 …
