WebCarcinoma in situ refers to an uncontrolled growth of cells that remains in the original location (in place) without invading surrounding tissue, as cancer cells eventually do. Carcinoma in situ however, is considered more serious than moderate dysplasia because the risk of local invasion is much higher.
WebTelomerase will speed up the rate of cell proliferation. Telomerase shortens telomeres, which delays cellular aging. Telomerase can eliminate telomere shortening and slows aging. Telomerase would have no effect on cellular aging. Telomerase can eliminate telomere shortening and slows aging. WebSep 5, 2014 · Cells can acquire resistance to N-methyl-N-nitrosurea, a methylating chemotherapy agent, by either reactivating a previously silenced MGMT gene, or by repressing the hMSH6 mismatch repair gene. The number of active MGMT molecules at the time of methylation determines the capacity of a cell for MGMT repair.
