It has been well established that inflammation plays a critical role in cancer. Chronic inflammation promotes tumorgenesis and metastasis, which suggests that anti-inflammation drugs could act as a tumor suppressor. It is known that the peroxisome proliferator-activated receptor γ (PPARγ) has been implicated in anti-inflammatory responses; however, the anti-tumor effects of PPARγ have not been intensively investigated. In this study, we examined the effects of PPARγ in cancer. We show that the activation of PPARγ by its agonist rosiglitazone (RGZ) reduces cell proliferation rate in inflammatory and tumor-derived U937 cells. Treatment of RGZ suppresses the expression Toll-like receptor 4 (TLR4) and decreases the production of TNF-α in LPS treated U937 cells. This suggests that NF-κB signaling may be involved in anti-tumor effect of RGZ. Our results demonstrate a role of PPARγ in regulation of NF-κB signaling by modulating TLR4 expression and TNF-α production.

Objective: To describe the outcomes of a partnership between a drug plan and pharmacists to switch patients from brand name dipeptidyl-peptidase-4 inhibitors to the generic alogliptin.
Study Design: Single-center, retrospective chart review.
Methods: Clinical pharmacists contacted patients with primary care providers within the health system affiliated with the drug plan to facilitate the switch.

Obesity is a chronic condition that causes significant morbidity and mortality in people in the United States and around the world. Traditional means of weight loss include diet, exercise, behavioral modifications, and surgery. New weight loss medications, glucagon-like peptide-1 receptor agonists, are revolutionizing the management of weight loss but have implications for fertility and pregnancy.

Combination therapies using checkpoint inhibitors with immunostimulatory agonists have attracted great attention due to their synergistic therapeutic effects for cancer treatment. However, such combination immunotherapies require specific timing of doses to show sufficient antitumor efficacy. Sequential treatment usually requires multiple administrations of the individual drugs at specific time points, thus increasing the complexity of the drug regimen and compromising patient compliance.

NMDA receptor ligands have therapeutic potential in neurological and psychiatric disorders. We designed ()-3-(5-thienyl)carboxamido-2-aminopropanoic acid derivatives with nanomolar agonist potencies at NMDA receptor subtypes (GluN12/A-D). These compounds are superagonists at GluN1/2C compared to glycine and partial to full agonists at GluN1/2A and GluN1/2D but display functional antagonism at GluN1/2B due to low agonist efficacy.

Importance: The increasing use of glucagon-like peptide-1 receptor agonists (GLP-1RA) demands a better understanding of their association with thyroid cancer.
Objective: To estimate the risk of incident thyroid cancer among adults with type 2 diabetes being treated with GLP-1RA vs other common glucose-lowering medications.
Design, Setting, And Participants: This was a prespecified secondary analysis of a target trial emulation of a comparative effectiveness study using claims data for enrollees in commercial, Medicare Advantage, and Medicare fee-for-service plans across the US.
