The cellular response to DNA damage is emerging as a promising target for cancer therapy. In the present study, the authors exploited the relationship between the level of the phosphorylated form of histone H2AX (?H2AX) and the extent of DNA damage and developed a quantitative, cell-based, high-content screening system for ...

PubMed ID:19584235
Brostallicin is a DNA minor groove binder in phase II clinical trials. Here, we show that brostallicin induces gamma-H2AX nuclear foci that colocalize with 53BP1 and are dependent on glutathione, as shown by inhibition of those gamma-H2AX foci by l-buthionine sulfoximine. To differentiate brostallicin from the clinically approved minor groove ... More

'Lifestyle-related diseases such as diabetes are steadily increasing worldwide. In Sudan, there are a variety of plant species used traditionally for the treatment of diabetes, obesity and other symptoms which need to be validated through scientific studies for their claimed traditional uses. Therefore, in the current study, the free radical ... More

'Burns are physically debilitating and potentially fatal injuries. The standard-of-care for burn wounds is the coverage with gauze dressings designed to minimize trauma to the regenerating epidermis and dermis during dressing changes. However, deep partial- and full-thickness burns always heal slowly when standard wound care alone is performed. We have ... More
A novel hydroxyphenyl hydrazone derivate YCL0426 inhibits cancer cell proliferation through sequestering iron.

PubMed ID:28926421
'Cancer cells have an increased requirement for iron than normal cells, and iron chelators are under active consideration for cancer treatment. The metal-sequestering potential and antiproliferative mechanisms of a novel hydroxyphenyl hydrazone derivate YCL0426 were investigated here. Antiproliferative activity of YCL0426 was detected by MTT assay. The iron-sequestering potential was ... More
