Trans-Petroselinic acid, the trans isomer of petroselinic acid and an isomer of oleic acid, is detected in the milk fat of cows, goats, and ewes, as well as human breast milk. In HepG2 cells, when treated with trans-petroselinic acid (100 μM), there is an increase in the cellular content of triacylglycerols and cholesterol esters. Additionally, it upregulates the transcription of genes associated with fatty acid synthesis (SREBP-1c, ACACA, FASN, SCD1) and cholesterol synthesis (HMGCR, HMGCS1, FDFT1, SREBP-2).

AUNP-12 TFA (NP-12 TFA) is a polypeptide antagonist in the pd-1 signaling pathway, which has the same antagonistic effect on pd-l1 and pd-l2, and can protect the proliferation and effector function of lymphocytes.
