Can p53 Activation induce more replicative senescence than apoptosis?

Hello all, I recently treated telomerase-inhibited A549 cells with 5 uM RITA, a p53 activator drug, and measured cell viability using the MTT assay. While wild type A549 experienced an expected...

Why must cancer xenografts occur in immunodeficient mice?

Hello, I'm curious as to why cancer xenografts must occur in immunodeficient mice. Ordinarily would the mouse immune system eliminate the cancer cells? And why would this not occur in regular...

Is it possible for two human neuronal cell lines to have different gene sequence for the same protein?

I am looking at the ATP1A2 (Sodium/Potassium ATPase alpha subunit 2) in two human neuronal cell lines. Expression levels of this protein seems to be almost equal when detected by one antibody....

Is CD44 degraded in lysosome together with hyaluronan after CD44 mediated endocytosis of hyaluronic acid?

Also when RHAMM binds hyaluronic acid, they get internalized, will RHAMM also be degraded? Or both CD44 and RHAMM will be transferred back to the cell membrane? Asking for breast cancer cell line...

Do you need the CMV enhancer before the CMV promotor for a proper function of CMV on the gene that follows?

I'm a student and I have to produce a cell line with a knockin for the NRF2 gene with GFP. I have to put a promotor in front of the GFP because the gene will be too far away from the promotor of...

Has anyone had luck using cell lines other than HEK 293 (such as COS1) to package lentivirus?

I am looking to package lentivirus in endothelial cells but I am opposed to using 293 cells due to personal ethics regarding the source. I have done some reading and saw that COS1, COS7, & CHO...
