DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Increased prevalence of sex chromosome aneuploidies in specific language impairment and dyslexia [PDF]

, 2013
© 2013 Mac Keith Press.Sex chromosome aneuploidies increase the risk of spoken or written language disorders but individuals with specific language impairment (SLI) or dyslexia do not routinely undergo cytogenetic analysis. We assess the frequency of sex

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Analysis of Y Chromosome Microdeletion in Indonesian Males

Makara Journal of Health Research, 2010
The aim of this study is to find out Y chromosome microdeletion in Indonesian azoospermic men. This study used the PCR method with five STS to locate deletion on three different subregions (AZFa, AZFb, and AZFc) of azoospermic men and one STS to amplify ...

Y chromosome and male infertility [PDF]

Andrologia, 1999
Male factor infertility accounts for about half the cases of couple infertility. In more than 60% of cases the origin of reduced testicular function is unknown but they may have an unidentified genetic anomaly. Microdeletions of the long arm of the human Y chromosome are associated with spermatogenic failure and have been used to define three regions ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Recombination dynamics of a human Y-chromosomal palindrome:rapid GC-biased gene conversion, multi-kilobase conversion tracts, and rare inversions [PDF]

, 2013
The male-specific region of the human Y chromosome (MSY) includes eight large inverted repeats (palindromes) in which arm-to-arm similarity exceeds 99.9%, due to gene conversion activity.

Chromosome-level genomes of Bruchinae reveal the rapid evolution of sex chromosomes and sex-biased genes in seed beetles

Genomics Communications
Structural variations (SVs) provide a material basis for genomic evolution, which can influence gene expression and three-dimensional (3D) genome structure, and even alter complex chromosomal features through regional recombination, copy number variation,

Y chromosome in health and diseases [PDF]

Cell & Bioscience, 2020
AbstractSex differences are prevalent in normal development, physiology and disease pathogeneses. Recent studies have demonstrated that mosaic loss of Y chromosome and aberrant activation of its genes could modify the disease processes in male biased manners.
