#Cyclooxygenase
Interesting work, it's becoming clear that @santiagozelenay.bsky.social's 2015 work on the COX-PGE axis' role in tumor immune evasion is robust (and also that we really need to focus on type I IFN in anti-tumor immunity).

Wenn Ibuprofen-Tabletten den Magen reizen, dann kann ich einfach ein Ibuprofen-Zäpfchen verwenden, oder?

Ja, kannst du.

Aber auch dann reizt das Ibuprofen den Magen.

COX, die Cyclooxygenase, ist ein Enzym, das aus der Arachidonsäure Prostaglandine bildet.

Warum reizen Schmerzmittel eigentlich den Magen?

Den Magen reizen vor allem unselektive COX-Hemmer, wie Ibuprofen, Acetylsalicylsäure und Diclofenac.

Sie hemmen unselektiv COX-1 und COX-2.

COX, die Cyclooxygenase, ist ein Enzym, das aus der Arachidonsäure Prostaglandine bildet.

Kann Ibuprofen tatsächlich Durchfall verursachen?

Ja.

Ibuprofen kann Durchfall verursachen.

Ihr erinnert euch?
COX, die Cyclooxygenase, ist ein Enzym, das aus der Arachidonsäure Prostaglandine bildet.

Prostaglandine setzen unter anderem die Darmbewegungen herab.

Please check out our recent preprint focused on understanding the cyclooxygenase signaling pathway and effects of pharmacologically inhibiting it in axolotl embryos! This work was spearheaded by MJ Marshall (molecular) and Raneesh Ramarapu (computational) in my lab with help from two undergrads.

Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) that acts as a cyclooxygenase (COX) inhibitor, works as both a Cox 1 and 2 inhibitor by blocking prostaglandins. One reason you’ll see many women touting its efficacy for menstrual cramps, they’re responsible for uterine contractions
Based on this we need better social and political dumb cocks inhibitors - I can’t image what he’d read out of “prostaglandin inhibitors” but we could try.

Beide adressieren dasselbe Enzym, die Cyclooxygenase. Kombiniert man beide, addieren, wenn nicht sogar multiplizieren sich die Nebenwirkungen, ohne ein Zugewinn an Wirkung erzielen zu können.
