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.

Authors: Kim HS, Hwang IG, Min HY, Bang YJ, Kim WH Abstract The purpose of the present study was to investigate the clinical significance of BRCA1/BRCA2 DNA repair associated (BRCA1/BRCA2) gene expression in patients with sporadic gastric cancer (GC) who had received postoperative adjuvant chemotherapy. Breast cancer type 1 and 2 susceptibility protein (BRCA1 and BRCA2) expression and BRCA1/BRCA2 mRNA expression were evaluated using immunohistochemistry (IHC) and in-situ hybridization (ISH) on tissue GC microarray tissues, in addition to reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The re...

In this study, the StCas9 derived from Streptococcus thermophilus together with the Drosha-mediated sgRNA-shRNA structure were combined to boost the G to A base editing on the IGF2 SNP site, which we called “SNP editing.” The codon-humanized StCas9 as we previously reported was firstly compared with the prevalently used SpCas9 derived from Streptococcus pyogenes using our idiomatic surrogate report assay, and the StCas9 demonstrated a comparable targeting activity. On the other hand, by combining shRNA with sgRNA, simultaneous gene silencing and genome targeting can be achieved. Thus, the novel IGF2.sgRNA-LIG4....

Conclusion: Our data suggests that the precancerous unstable CNVs with potentially predisposing genetic backgrounds may foster the onset of driver mutations and the development of independent SM-GGNs during the local stimulation of mutagens. Introduction The widespread use of advanced chest computed tomography (CT) for lung cancer screening has facilitated the detection of ground-glass nodules (GGNs) (1–3). Recent data indicates that up to 20% of GGN patients (3% of the screening population) are diagnosed with synchronous multiple ground-glass nodules (SM-GGNs) (4). GGNs are like atypical adenomatous hyperplasi...

Conclusions In this review, we analyzed mechanisms through which mitobolites, a distinct set of mitochondria-generated metabolites, can be released from mitochondria and then act as second messengers that contribute to cellular and organismal aging by regulating longevity-defining processes outside of mitochondria. Our analysis indicates that in eukaryotes across phyla, these second messengers of cellular aging exhibit the following common features: (1) they are produced in mitochondria in response to certain changes in the nutrient, stress, proliferation or age status of the cell; it remains unknown, however, what kind o...

Conclusion and Perspectives Collectively, previous studies showed that numerous types of TCMs protect against AKI via different mechanisms of action, including inhibiting inflammation, cell apoptosis, necroptosis, ferroptosis, and restraining oxidative stress etc. These data support the potential application of these TCMs as novel therapeutic agents in treating patients with AKI. Although some TCMs have entered preclinical trials, it is essential to initiate pre-clinical pharmacologic and toxicologic trials and clinical trials to evaluate the efficacy and safety of TCMs usage. Moreover, considering that some TCMs are dele...
