Ribosomal S6 Kinase (RSK) is a family of protein kinases involved in signal transduction. There are two subfamilies of rsk, p90rsk, also known as MAPK-activated protein kinase-1 (MAPKAP-K1), and p70rsk, also known as S6-H1 Kinase or simply S6 Kinase. There are three variants of p90rsk in humans, rsk 1-3. Rsks are serine/threonine kinases and are activated by the MAPK/ERK pathway. There are two known mammalian homologues of S6 Kinase: S6K1 and S6K2. Rsk is named for ribosomal protein s6, part of the translational machinery, but several other substrates have been identified, including other ribosomal proteins. Cytosolic substrates of p90rsk include protein phosphatase 1; glycogen synthase kinase 3 (GSK3); L1 CAM, a neural cell adhesion molecule, the Ras exchange factor; and Myt1, an inhibitor of cdc2. p90rsk also regulates transcription factors including cAMP response element-binding protein (CREB); estrogen receptor-α (ERα); IκBα/NF-κB; and c-Fos.

Bupivacaine hydrochloride

Bupivacaine Hydrochloride is a local anaesthetic drug belonging to the amino amide group.Target: OthersBupivacaine hydrochloride is an effective local anesthetic agent. It has a rapid onset time, a high frequency of surgical anesthesia, a long duration, and a low incidence of side effects [1]. Median doses of bupivacaine (in milligrams per kilogram) producing asystole in protocol 1 were for 17.7 for saline, 27.6 for 10% Intralipid, 49.7 for 20% Intralipid, and 82.0 for 30% Intralipid (P < 0.001 for differences between all groups). Differences in mean +/- SE concentrations of bupivacaine in plasma (in micrograms per milliliter) were significant (P < 0.05) for the difference between saline (93.3 +/- 7.6) and 30% Intralipid (212 +/- 45). In protocol 2, lipid infusion increased the dose of bupivacaine required to cause death in 50% of animals by 48%, from 12.5 to 18.5 mg/kg. The mean lipid:aqueous ratio of concentrations of bupivacaine in a plasma-Intralipid mixture was 11.9 +/- 1.77 (n = 3) [2].
