Hippophae salicifolia (willow-leaved sea buckthorn) is restricted to the Himalayas, to the south of the common sea buckthorn, growing at high altitudes in dry valleys; it differs from H. rhamnoides in having broader (to 10 mm (3 ⁄ 8 in)) [citation needed] and greener (less silvery) leaves, and yellow berries. A wild variant occurs in the same ...
Without cyclin, CDK is less active than in the cyclin-CDK heterodimer complex. [ 5 ] [ 6 ] CDKs phosphorylate proteins on serine (S) or threonine (T) residues. The specificity of CDKs for their substrates is defined by the S/T-P-X-K/R sequence, where S/T is the phosphorylation site, P is proline, X is any amino acid, and the sequence ends with ...
The names "Apple of Sodom" and "Dead Sea Apple" stem from the ancient authors Josephus and Tacitus, who described the plant growing in the area of biblical Sodom. [6] Although not native to the New World , the plant (and other related milkweed species) has been cultivated, and feeds monarch butterfly caterpillars, in places such as California ...
Known CDK inhibitors are p21Cip1 and p27Kip1 . [ 30 ] Drugs that inhibit Cdk2 and arrest the cell cycle, such as GW8510 and the experimental cancer drug seliciclib , may reduce the sensitivity of the epithelium to many cell cycle-active antitumor agents and, therefore, represent a strategy for prevention of chemotherapy-induced alopecia .
