BlindAbstractThe higher-order inositol phosphate second messengers inositol tetrakisphosphate (IP4), inositol pentakisphosphate (IP5) and inositol hexakisphosphate (IP6) are important signaling molecules that regulate DNA-damage repair, cohesin dynamics, RNA-editing, retroviral assembly, nuclear transport, phosphorylation, acetylation, crotonylation, and ubiquitination. This functional diversity has made understanding how inositol polyphosphates regulate cellular processes challenging to dissect. However, some i...

Orbitides are a class of small naturally occurring cyclic peptides with structural and functional diversities. Their chemical properties make this class feasible to be obtained by solid phase peptide synthesis (SPPS). Therefore, this synthetic accessibility enables useful application and facilitates the identification of analogues, bioactivity studies, and thus, enables them to be applied to obtain peptide libraries. The aim of this work was to investigate the effects of orbitides and their linear synthetic analogues on the migration of neonatal human foreskin fibroblasts. The screening of linear peptide analogues, origina...

Although mild acute kidney injury (AKI) commonly encountered in clinical practice may resolve completely, it is increasingly apparent from human and animal data that more severe AKI often progresses to chronic kidney disease (CKD).1 After kidney injury, tubular epithelial cells (TECs) are primarily responsible for regeneration and repair by proliferating, de-differentiating, migrating, and redifferentiating.2 Depending on the extent of injury, additional repair may occur through fibrosis, the replacement of nonviable kidney tissue by the extracellular matrix.

Science tells us that a lot of good things happen in our brains while we sleep – learning and memories are consolidated and waste is removed, among other things. New research shows for the first time that important immune cells called microglia – which play an important role in reorganizing the connections between nerve cells, fighting infections, and repairing damage – are also primarily active while we sleep.

Conclusions: We observed a significant inverse relationship between surgeon volume and complication rates when controlling for patient and injury characteristics. In contrast to previous research, a volume–outcome relationship was not observed at the hospital level. These results suggest that such complex injuries should be triaged to the most experienced providers. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

The latest crowdfunded research project undertaken by the SENS Research Foundation involves using the genetically engineered maximally modifiable mouse lineage in order to demonstrate the ability to copy a version of the ATP8 mitochondrial gene into the cell nucleus, a process known as allotopic expression, and thus prevent mutational damage to this gene from degrading mitochondrial function. This is a modest step on the road towards bringing this class of genetic engineering project to the point of readiness for commercial development, when a biotech startup company could be created to carry it forward. In just a f...

Authors: Morgans AK, Szymaniak BM Abstract The landscape of genetic testing for prostate cancer is rapidly evolving. There is increasing evidence that individuals with germline mutations in DNA-repair genes are more responsive to targeted therapies. Due to potential implications for treatment, these genes should be taken into consideration when determining the scope of genetic testing. PMID: 31629435 [PubMed - in process]

Authors: Carroll PR, Witte JS, Parsons JK Abstract Men with germline mutations in DNA repair genes are at an increased risk of prostate cancer. These germline mutations are commonly seen in conjunction with somatic DNA repair gene mutations in prostate tumors. This indicates that men with a personal or family history of prostate cancer-as well as other cancer syndromes arising from mutations in DNA repair genes-should be considered for genetic testing and counseling.

Authors: Knudsen KE Abstract Despite significant advances in understanding the biology of advanced prostate cancer and approval of novel therapeutic agents, there is no durable cure for metastatic disease. Recent findings unmasked the importance of androgen receptor (AR) signaling in regulation of DNA repair, and alterations of the AR-DNA repair factor axis were shown to promote aggressive phenotypes including metastasis. These and related findings underscore the importance of determining impact AR-DNA repair factor alterations on prostate cancer progression. PMID: 31629421 [PubMed - in process]
