Examining the role of freebase nicotine in the harm reduction potential of oral nicotine pouches versus moist snuff: A randomized crossover trial

open access: yesAddiction, EarlyView.
Abstract Background and aims Oral nicotine pouches (ONPs) contain varying proportions of freebase nicotine (FBN), with higher FBN expected to increase nicotine delivery across the oral mucosa. Because ONPs contain fewer toxicants than moist snuff and may serve as a reduced harm alternative for smokeless tobacco, we compared how the FBN in ONPs affects ...

CALR/HIF‐1α Positive Feedback Loop Drives CALR Upregulation to Promote EMT‐Mediated Bladder Cancer Progression via ROS/AKT Axis

open access: yesCancer Science, EarlyView.
This study first found that the high expression of CALR is due to a novel positive feedback loop with HIF‐1α in the tumor microenvironment: CALR stabilizes HIF‐1α protein, while HIF‐1α transcriptionally upregulates CALR expression, thereby self‐sustaining its high expression levels in BLCA.
