Katuk is one of the most common plant species in Indonesia which is known by the community to treat the disease, especially the leaf part can be used as a milk mat. katuk leaf (Sauropus androgynus (L) Merr) also contains saponin, flavonoid and tannin Inhibits the growth of bacteria one of the bacteria that cause acne bacteria P. acnes and S. epidermidis. The aim of this research is to know the antibacterial inhibition effect of katuk leaf extract to growth of P. acnes and S. epidermidis using Cup-plate or pit diffusion method with concentration 20%, 40%, 60%, 80% and 100%. Clindamycin is used as a positive control and aquades as a negative control. The leaves of katuk extracted with 70% ethanol solvent showed no antibacterial activity against P. acnes bacteria while against S. epidermidis bacteria showed antibacterial activity. The highest antibacterial activity at 100% concentration with 18.17 mm zone diameter belong to the category of inhibitory resistance of medium growth and the lowest concentration at concentration of 40% with 16.68 mm inhibitory zone diameter belong to the weak growth inhibitory response category. The minimum inhibitory concentrations produced in S. epidermidis bacteria were 39% - 36%. Keywords : Sauropus androgynus, Propionibacterium acnes, Staphilococcus epidermidis, Minimal Inhibitory Concentration.

The overall survival of pancreatic ductal adenocarcinoma (PDAC) remains poor and its incidence is rising. Targetable mutations in PDAC are rare, thus novel therapeutic approaches are needed. Protein arginine methyltransferase 5 (PRMT5) overexpression is associated with worse survival and inhibition of PRMT5 results in decreased cancer growth across multiple cancers, including PDAC. Emerging evidence also suggests that altered RNA processing is a driver in PDAC tumorigenesis and creates a partial dependency on this process. PRMT5 inhibition induces altered splicing and this vulnerability can be exploited as a novel therapeutic approach. Three possible biological pathways underpinning the action of PRMT5 inhibitors are discussed; c-Myc regulation appears central to its action in the PDAC setting. Whilst homozygous MTAP deletion and symmetrical dimethylation levels are associated with increased sensitivity to PRMT5 inhibition, neither measure robustly predicts its growth inhibitory response. The immunomodulatory effect of PRMT5 inhibitors on the tumour microenvironment will also be discussed, based on emerging evidence that PDAC stroma has a significant bearing on disease behaviour and response to therapy. Lastly, with the above caveats in mind, current knowledge gaps and the implications and rationales for PRMT5 inhibitor development in PDAC will be explored.
