Some of these clinical trials have shown various degrees of success. Aishwarya rai nude sex photos. Microtubules are involved in maintaining the structure of the cell and, together with microfilaments and intermediate filaments, they form the cytoskeleton [ - ].
The studies revealed that this cytostatic effect was associated with the cell cycle arrest in sub-G1 phase and downregulation of the CDK4, CDK6 and cyclin D1 protein levels [ ].

Promotion of microtubule assembly in vitro by taxol. This family of compounds acts as non-competitive inhibitors of vinblastine binding to tubulin, as indicated in [ ]. They are also involved in chromosome separation mitosis and meiosisand are the major constituents of mitotic spindles, which are used to pull apart eukaryotic chromosomes [ - ].
It also potently inhibits the growth of paclitaxel-resistant, multidrug-resistant carcinoma cell lines [ ].
Therefore, inhibition of CDKs, through the insertion of small molecules into its ATP-binding pocket has emerged as a potential therapy method for cancers [ 56 ].
