Eighty seven women with benign breast lesion, 120 patients with breast cancer (BC) and one hundred controls were included in the study. Quantification of mtDNA and nDNA was done by qPCR. Global DNA methylation was measured using ELISA. Circulating cell-free nDNA and mtDNA were significantly elevated in BC and benign breast lesions patients. Global methylation was significantly low in BC patients. Combining the studied parameters in one panel, nDNA/mtDNA/hypomethylation, improved their sensitivity in detecting BC to reach 92.5%. Circulating cell-free nDNA, mtDNA and global DNA hypomethylation can be used as diagnostic and prognostic markers for BC.

Alcohol consumption is an important risk factor for multiple diseases. It is typically assessed via self-report, which is open to measurement error through recall bias. Instead, molecular data such as blood-based DNA methylation (DNAm) could be used to derive a more objective measure of alcohol consumption by incorporating information from cytosine-phosphate-guanine (CpG) sites known to be linked to the trait.

Colorectal cancer (CRC) is a leading cause of cancer-related deaths globally, necessitating the development of sensitive and minimally invasive diagnostic approaches. In this study, we present a novel diagnostic strategy by integrating dumbbell probe-mediated CRISPR/Cas13a with nicking-induced DNA cascade reaction (DP-bridged Cas13a/NDCR) for highly sensitive microRNA (miRNA) detection. Target miRNA triggers Cas13a-mediated cleavage of the dumbbell probe, releasing an intermediate strand that hybridizes with a methylene blue-labeled hairpin probe on the electrode surface.

Bacterial resistance is a global public health problem because of the ineffectiveness of conventional antibiotics against super pathogens. To counter this situation, the search for or design of new molecules is essential to inhibit the key proteins involved in several stages of bacterial infection. One of these key proteins is DNA gyrase, which is responsible for packaging and unfolding of DNA chains during replication.

: Alpha radionuclide therapy has emerged as a promising novel strategy for cancer treatment; however, the therapeutic potential of Ac-labeled peptides in pancreatic cancer remains uninvestigated. : In the cytotoxicity study, tumor cells were incubated with Ac-DOTA-RGD. DNA damage responses (γH2AX and 53BP1) were detected using flowcytometry or immunohistochemistry analysis.
