AI Article Synopsis

  • Glutathione-responsive nanogels (CDNPs) were created using a crosslinker and combined with the BRAF inhibitor dabrafenib and the COX2 inhibitor celecoxib.
  • These nanogels effectively trigger pyroptosis in tumor cells, boosting the body's antitumor immune response.
  • When used alongside the αPD-1 antibody, CDNPs significantly reduced tumor growth and extended survival in a melanoma mouse model.

Article Abstract

Glutathione-responsive nanogels (CDNPs) crosslinked crosslinker DBHD with the BRAF inhibitor dabrafenib and the COX2 inhibitor celecoxib were fabricated. The CDNPs can effectively induce tumor cell pyroptosis to activate robust antitumor immunity. Additionally, CDNPs combined with αPD-1 antibody greatly inhibited tumor growth in a melanoma mouse model with a prolonged survival time.

This study aimed to compare the inhibitory effect of flunixin meglumine and meloxicam on the smooth muscles of the gastrointestinal tract in male cattle. Tissue samples, including the abomasum, ileum, proximal loop and centripetal gyri of the ascending colon, were collected from routinely slaughtered male cattle. These samples were sectioned into strips and mounted in an isolated tissue bath system.

Background: Nasopharyngeal cancer (NPC) is prevalent in Southeast Asia and North Africa, which is generally associated with limited treatment options and poor patient prognosis.

Objective: Ferroptosis is a recently observed cell death modality and has been shown to link to the efficacy of different anti-cancer treatments, thus offering opportunities to the development of novel therapies. This study aims to investigate the potentiating effects of COX-2 inhibitors on ferroptosis in nasopharyngeal cancer.

: Peroxisome proliferator-activated receptor γ (PPARγ) plays a key role in mediating anti-inflammatory and anticancer effects in the tumor microenvironment. Kaurenoic acid (KA), a diterpene compound isolated from (L.) Pruski, has been demonstrated to exert anti-inflammatory, anticancer, and antihuman immunodeficiency virus effects.
