Inhibitory effects of Rhenium-188-labeled Herceptin on prostate cancer cell growth: a possible radioimmunotherapy to prostate carcinoma.

abstract：:The existence of a correlation between experimental probabilities of cell inactivation by charged particles and calculated probabilities for K-vacancy production in heavy atoms (C, N, O, P) of the DNA of cell nuclei is established. Both phenomena display a similar dependence upon the linear energy transfer (LET) of in...

abstract：PURPOSE:The molecular basis of gene regulation in cells exposed to ionising radiation is not fully understood. Gene regulation occurs at the transcriptional and post-transcriptional levels. Recent studies have suggested that micro-RNA (miRNA) plays a significant role at the post-transcriptional gene regulation. miRNA a...
