Researchers have identified a key contributor to prostate cancer metastasis in a study published in the journal Oncogene. The upregulation of P-Rex1, a Rac-selective guanine nucleotide exchange factor (GEF), was found to strongly correlate with metastatic phenotypes in both prostate cancer cell lines and human prostate cancer specimens. This correlation

A study conducted by investigators in the United States aimed to verify the performance of EGFR fluorescence in situ hybridization (FISH) in Japanese non-small-cell lung cancer (NSCLC) patients. The researchers enrolled a cohort of 44 Japanese patients with recurrent NSCLC after surgery and treated them with gefitinib 250 mg daily.

In a recent study, investigators from South Korea have reported that methylation of DNA plays a regulatory role in DNA metabolism. The researchers found that the Escherichia coli DNA adenine methyltransferase methylates the N6 positions of adenines in the sequence 5'-GATC-3', which exists in the fully methylated

Researchers from Johns Hopkins University, led by H. Ding, have made a groundbreaking discovery in the field of DNA chemistry. By using phenylselenyl-modified thymidine, they have identified a new mechanism for producing DNA interstrand cross-links (ICLs) via two distinct pathways: photolysis and oxidation. This finding sheds new light on the
