we observe apparent changes of ATM in M059K cells after the cells were treated with the miR 100 chemical or Dicer siRNA, which might be since the ATM level is normal in such cells and the cells might be less sensitive to any stimulator for further increasing theATMlevel. We made the construct Everolimus ic50 encoding the pri miR 100 in lentivirus vector and examined the consequence of up regulating miR 100 on the ATM expression in M059K cells, to confirm the connection between miR100 and ATM. The outcome showed that whenever miR 100 was overexpressed in M059K cells, the level of ATM significantly decreased. Similar results were seen from other glioma cell lines, U87MG cells and lung cancer cell lines, 95C and 95D cells. These results confirm that the low expression of ATM in M059J cells is especially due to the over expression of miR 100. However, currently, we can’t exclude another Lymph node possibility that methylation can also are likely involved in the lower expression ofATMbecause the miR 100 chemical could not completely restore the ATM level of M059J cells shown in M059K cells, which needs future studies to try. To handle the question if the levels of miR 100 and ATM was affected by DNA PKcs, we discovered the effects of the precise siRNA against PRKDC on the levels of miR 100 and ATM in M059K cells. The results showed that neither the level of miR 100 or the level ofATMprotein transformed after DNA PKcswasefficiently pulled down in M059K cells. These results exclude the possibility that the lower term of ATM in M059J cells is just a direct effect of missing DNA PKcs. Currently, we still can not answer how miR 100 expression is regulated while there is no difference in the transcript sequence of miR 100 between M059J and M059K cells, which needs more experiments to obtain the answer. Levels were measured miR 100 by us in several brain tumor cell lines. The outcomes show that the amount of miR GW0742 100 varies in different cell lines although the quantities of miR100 were not affected by radiation. The later results are in keeping with that ATM activity is affected, but ATM expression level isn’t affected by the general anxiety including DNA damage response. The degree of miR 100 in M059J is greater than in M059K but lower than in U87MG. The reason behind the high level of miR 100 in U87MG cells not evoking the lower level of ATM may be due to the heterogeneous top features of cancer cell lines. Similar to MO59K cells, the inhibitor of miR 100 couldn’t further boost the ATM amount in U87MG cells. As stated above this can be due to the same reason. The gene expression is controlled by many positive or negative factors including transcriptional factors, enhancers and inhibitors etc. These facets might be proteins or small non code RNA including miRNA.
