Caught with One's Zinc Fingers in the Genome Integrity Cookie Jar.

Caught with One's Zinc Fingers in the Genome Integrity Cookie Jar. Trends Genet. 2018 Jan 19;: Authors: Vilas CK, Emery LE, Denchi EL, Miller KM Abstract Zinc finger (ZnF) domains are present in at least 5% of human proteins. First characterized as binding to DNA, ZnFs display extraordinary binding plasticity and can bind to RNA, lipids, proteins, and protein post-translational modifications (PTMs). The diverse binding properties of ZnFs have made their functional characterization challenging. While once confined to large and poorly characterized protein families, proteomic, cellular, and molecular studies have begun to shed light on their involvement as protectors of the genome. We focus here on the emergent roles of ZnF domain-containing proteins in promoting genome integrity, including their involvement in telomere maintenance and DNA repair. These findings have highlighted the need for further characterization of ZnF proteins, which can reveal the functions of this large gene class in normal cell function and human diseases, including those involving genome instability such as aging and cancer.

Hodge, David Bosler, Lauren Rubinstein, Navid Sadri, Shashirekha ShettyAbstractThe inv(3)(q21q26.2) altering a single chromosome 3 homolog is an established myeloid malignancy-associated entity. Comparatively, double inv(3) cases involving both homologs are exceedingly rare with 13 reports across AML, CML and MDS. This scarcity was confirmed by finding only 2 new cases out of 34,898 bone marrows collected during a 55 year period at a large medical center (0.0005%). The double inv(3) was detected by karyotype and confirmed by FI...

The current study aimed to investigate the effect of alpinumisoflavone (AIF) on CRC and its possible molecular mechanism.MethodsHCT-116 and SW480 cells were chosen as cell model to study the anti-cancer activity of AIF in vitro experiments. Cells proliferative capacity and clonogenicity were examined by CCK-8 assay and colony formation assay, while cell apoptosis was detec...

However, the current preparation process to synthesize 1-CG via transesterification from methyl caffeate (MC) and glycerin was not economic due to long reaction time or adding extra field. Therefore, an enzymatic synthesis with deep eutectic solvent chloride-urea (ChCl-urea) in a m...

A geroprotector is a drug or supplement that either slows the underlying causes of aging or produces a greater resistance to the damage of aging. In either case health is prolonged and mortality decreased. Calorie restriction mimetics are the best example of the type, but the category is expansive enough to include well known drugs such as aspirin. As you might imagine of a class of treatments that includes aspirin, the size of effect when it comes to additional years of life is fairly small, even in those cases in which the benefits are reliable. Geroprotectors largely work through upregulation of stress responses, someth...
