Protecting exons from deleterious R-loops: a potential advantage of having introns

Biology Direct, 2007
Background Accumulating evidence indicates that the nascent RNA can invade and pair with one strand of DNA, forming an R-loop structure that threatens the stability of the genome. In addition, the cost and benefit of introns are still in debate.

QUALITATIVE ASSESSMENT OF CADMIUM STRESS USING GENOME TEMPLATE STABILITY IN Hordeum vulgare

Egyptian Journal of Genetics and Cytology, 2010
Cadmium, a non essential heavy metal, does not play any metabolic role and is considered as toxic element even at very low concentration. It is mainly generated through anthropogenic activities, such as mining deposits, aerial fallout from smelters and from industrial, agricultural, energy and municipal sources (McGrath et al., 2001; McBride, 2003 ...

Glycinebetaine reduces oxidative injury and enhances fluoride stress tolerance via improving antioxidant enzymes, proline and genomic template stability in Cajanus cajan L.

South African Journal of Botany, 2017
Abstract Excess of fluoride (F) in irrigation water is a serious threat inducing variety of deleterious impacts in plants via over-production of active oxygen species (AOS), modifying antioxidant enzymes and nucleic acid. Present study was aimed to monitor protective functions of glycinebetaine (GB) against F-toxicity in Cajanus cajan L. GB is an

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

Molecular 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

Genetic dissection of the RNA polymerase II transcription cycle

eLife, 2022
How DNA sequence affects the dynamics and position of RNA Polymerase II (Pol II) during transcription remains poorly understood. Here, we used naturally occurring genetic variation in F1 hybrid mice to explore how DNA sequence differences affect the ...

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

The chromatin assembly factor 1 promotes Rad51-dependent template switches at replication forks by counteracting D-loop disassembly by the RecQ-type helicase Rqh1.

PLoS Biology, 2014
At blocked replication forks, homologous recombination mediates the nascent strands to switch template in order to ensure replication restart, but faulty template switches underlie genome rearrangements in cancer cells and genomic disorders ...

Genetic analysis for identification, genomic template stability in hybrids and barcodes of the Vanda species (Orchidaceae) of Thailand

AFRICAN JOURNAL OF BIOTECHNOLOGY, 2012
Molecular data supporting morphological characters for identification and specific markers for ornamental Vanda species in Thailand can be achieved for economic means. The ten native Thai species that have been explored and identified are Vanda bensonii, Vanda brunnea, Vanda coerulea, Vanda coerulescens, Vanda denisoniana, Vanda pumila, Vanda lilacina,

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).
