A review of drug resistance in cancer analyses each biological determinant of resistance separately and discusses existing and new therapeutic strategies to combat the problem as a whole. Chamla and Begueret (1982) showed that the 'defect' was one of decreased permeability to the drug. The effectiveness of microtubule-targeting drugs for cancer therapy has been impaired by various side effects, notably neurological and hematological toxicities. Continued investigation of the mechanisms of action of microtubule-targeting drugs, development and discovery of new drugs, and exploring new treatment strategies that reduce side effects and circumvent drug resistance may provide more effective therapeutic options for cancer patients. Antibiotic Resistance. The primary mechanism of action of colchicine is tubulin disruption. Colchicine-resistant mutants of Chinese hamster ovary (CHO) cells have been found to have a change in the entry of drugs into cells, altered binding of colchicine to its intracellular target, or an altered tubulin. 2020 May 1;24(3):233-240. doi: 10.4196/kjpp.2020.24.3.233.PeerJ.

Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. This leads to subsequent down regulation of multiple inflammatory pathways and modulation of innate immunity. Acquired antimicrobial resistance generally can be ascribed to one of five mechanisms. Colchicine is widely used in plant breeding by inducing polyploidy in plant cells to produce new or improved varieties, strains and cultivars. Cancer chemotherapy resistance (MDR) is the innate and/or acquired ability of cancer cells to evade the effects of chemotherapeutics and is one of the most pressing major dilemmas in cancer therapy.
Drug resistance is another notorious factor that thwarts the effectiveness of these agents, as with many other cancer chemotherapeutics.
Early study demonstrated that colchicine disrupts the mitotic spindle.
This makes the drugs less effective.Microbes are very small living organisms, like bacteria. Epub 2009 Aug 11.Nat Rev Cancer. 2004 Apr;4(4):253-65. doi: 10.1038/nrc1317.Korean J Physiol Pharmacol. There are several common mechanisms for drug resistance, which are summarized in Figure 1. Bacteria develop resistance mechanisms by using instructions provided by their DNA. Mechanism of action for colchicine in gout . Chemotherapy resistance can arise due to several host or tumor-related factors.
