Cytogenetic study and pollen viability of three populations of Diplotaxis harra (Brassicaceae) in Iran [PDF]
Journal of Cell and Molecular Research, 2014 In this study, we examined the chromosome number, detailed male meiosis, microsporogenesis, pollen fertility and distribution of cytotypes of Diplotaxis harra (Forssk.) Boiss. This is the first cytogenetic report of the taxon.

On the Order of Gene Distribution on Chromosomes Across the Animal Kingdom [PDF]
arXiv, 2019 Background. The large-scale pattern of distribution of genes on the chromosomes in the known animal genomes is not well characterized. We hypothesized that individual genes will be distributed on chromosomes in a mathematically ordered manner across the animal kingdom. Results.

Molecular Oncology, EarlyView.MET variants in the N‐lobe of the kinase domain, found in hereditary papillary renal cell carcinoma, require ligand stimulation to promote cell transformation, in contrast to other RTK variants. This suggests that HGF expression in the microenvironment is important for tumor growth in such patients. Their sensitivity to MET inhibitors opens the way for

MEIOSIS: HOW TO HALVE THE CHROMOSOME NUMBER
Вавиловский журнал генетики и селекции, 2014 The notion of meiosis has been changed and refined for over a century since the discovery of this complicated way of cell division. Its success depends on precise time and space orchestration of many processes, such as chromosome replication, packaging ...

Cytogenetic study of two Solenanthus Ledeb. species (Boraginaceae) in Iran [PDF]
Journal of Cell and Molecular Research, 2013 Chromosome number, meiotic behavior, and pollen viability were analyzed in 2 species of genus Solenanthus, S. stamineus (Desf.) Wettst. and S. circinnatus Ledeb, from Iran. This report is the first cytogenetic analysis of these species.

Can entropy save bacteria? [PDF]
Suckjoon Jun and Andrew Wright, Nature Reviews Microbiology,
August issue (2010), 2008 This article presents a physical biology approach to understanding organization and segregation of bacterial chromosomes. The author uses a "piston" analogy for bacterial chromosomes in a cell, which leads to a phase diagram for the organization of two athermal chains confined in a closed geometry characterized by two length scales (length and width ...

Molecular Oncology, EarlyView.The complex mode of action of the topoisomerase II inhibitor etoposide in triggering apoptosis involves several mechanisms: overexpression of the mitochondrial protein VDAC1, leading to its oligomerization and formation of a large channel that mediates the release of pro‐apoptotic protein; and overexpression of the apoptosis regulators p53, Bax, and ...

Using sequencing coverage statistics to identify sex chromosomes in minke whales [PDF]
arXiv, 2019 The ever-increasing number of genome sequencing and resequencing projects is a central source of insights into the ecology and evolution of non-model organisms. An important aspect of genomics is the elucidation of sex determination systems and identifying genes on sex chromosomes.

Molecular and functional profiling unravels targetable vulnerabilities in colorectal cancer
Molecular Oncology, EarlyView.We used whole exome and RNA‐sequencing to profile divergent genomic and transcriptomic landscapes of microsatellite stable (MSS) and microsatellite instable (MSI) colorectal cancer. Alterations were classified using a computational score for integrative cancer variant annotation and prioritization.
