Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

MITF maintains genome stability in nonmelanocyte lineages

open access: yesMolecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

The Effects of Zinc Phosphide and Brodifacoum on Mitotic Index and Chromosomal Aberrations in Germ Cells of Wild type and Laboratory Mice (Mus Musculus) [PDF]

open access: yesEngineering and Technology Journal, 2014
The genotoxic effects of two wildy used rodenticides in Iraq (Zinc phosphide and Brodifacoum) were studied in wildtype and Balbc mice,by using mitotic index(MI) and chromosomal aberration (CA).

Applicability of mitotic figure counting by deep learning: a development and pan‐cancer validation study

open access: yesFEBS Open Bio, EarlyView.
In this study, we developed a deep learning method for mitotic figure counting in H&E‐stained whole‐slide images and evaluated its prognostic impact in 13 external validation cohorts from seven different cancer types. Patients with more mitotic figures per mm2 had significantly worse patient outcome in all the studied cancer types except colorectal ...

Sensitivity of vegetables seeds in the assessment of water quality in bioassays [PDF]

open access: yesBiotemas, 2012
Since seeds tolerate sress levels and their vital functions are correlated to the environment, the study aimed to evaluate lettuce and onions as bioindicators to test water quality, and the parameters to assess water quality vary according to the seasons

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

open access: yesFEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...
