Transcriptional coupling (Mfd) and DNA damage scanning (DisA) coordinate excision repair events for efficient Bacillus subtilis spore outgrowth

open access: yesMicrobiologyOpen, 2018
The absence of base excision repair (BER) proteins involved in processing ROS‐promoted genetic insults activates a DNA damage scanning (DisA)‐dependent checkpoint event in outgrowing Bacillus subtilis spores.

Initiating base excision repair in chromatin [PDF]

open access: yesDNA Repair, 2018
The base excision repair (BER) pathway removes modified nucleobases that can be deleterious to an organism. BER is initiated by a glycosylase, which finds and removes these modified nucleobases. Most of the characterization of glycosylase activity has been conducted in the context of DNA oligomer substrates.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Cerebrospinal Fluid Leak in Transnasal Transsphenoidal Surgery for Pituitary Adenoma and its Management

open access: yesBengal Journal of Otolaryngology and Head Neck Surgery, 2021
Introduction Over the past few decades endoscopic transnasal transsphenoidal (ETNTS) approach has been practised for excision of pituitary tumours which has minimised the rate of complications and morbidity.

Triple negative breast cancers have a reduced expression of DNA repair genes. [PDF]

open access: yesPLoS ONE, 2013
DNA repair is a key determinant in the cellular response to therapy and tumor repair status could play an important role in tailoring patient therapy. Our goal was to evaluate the mRNA of 13 genes involved in different DNA repair pathways (base excision,

Update on Poly-ADP-ribose polymerase inhibition for ovarian cancer treatment [PDF]

open access: yes, 2016
Background: Despite standard treatment for epithelial ovarian cancer (EOC), that involves cytoreductive surgery followed by platinum-based chemotherapy, and initial high response rates to these, up to 80 % of patients experience relapses with a median ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Chemical Biology of Mammalian DNA Repair

open access: yesCHIMIA, 2001
Damage to the heterocyclic bases of DNA in the genome is mainly corrected by the base excision repair (BER) or nucleotide excision repair (NER) pathways.

Decline of DNA damage response along with myogenic differentiation

open access: yesLife Science Alliance
In postmitotic myotubes, DNA repair processes such as Base Excision Repair, and Non-Homologous End Joining are weakened compared with the proliferative precursors myoblasts. DNA integrity is incessantly confronted to agents inducing DNA lesions.

The Base Excision Repair Pathway in the Nematode Caenorhabditis elegans

open access: yesFrontiers in Cell and Developmental Biology, 2020
Exogenous and endogenous damage to the DNA is inevitable. Several DNA repair pathways including base excision, nucleotide excision, mismatch, homologous and non-homologous recombinations are conserved across all organisms to faithfully maintain the ...
