Revisiting Clonal Evolution Through the Light of Retrotransposons

BioEssays, EarlyView.
We propose integrating retrotransposons into the clonal evolution model of cancer. Retrotransposons can modulate cancer cell fitness, potentially influencing clonal dynamics. They might also induce lineage violations via cell fusion or horizontal transfer.

Genetic diversity of wheat (Triticum aestivum L.) plants-regenerants produced by anther culture

Вавиловский журнал генетики и селекции, 2016
The study of genetic diversity of wheat (Triticum aestivum L.) plants-regenerants produced by anther culture method from hybrids involved in the Latvian wheat breeding programme was performed. Flow cytometry was used to test ploidy of 3×103 cells of each

Genome composition of 'Elatior'-begonias hybrids analyzed by genomic in situ hybridisation [PDF]

, 2010
Interspecific hybridization of various tuberous Begonia species hybrids with Begonia socotrana results in so-called 'Elatior'-begonias hybrids (B. x hiemalis Fotsch).

A Role for Ploidy in Heart Regeneration [PDF]

Developmental Cell, 2018
There is mounting circumstantial evidence that ploidy, a cell's relative DNA content, is in part responsible for the differential cardiac regenerative capacity observed between regenerative and non-regenerative organisms. In this issue of Developmental Cell, González-Rosa et al.

Common but Least Noticed: Diversity of the Mangrove Fern Acrostichum aureum in Hainan Island, China

Biological Diversity, EarlyView.
Acrostichum aureum across nine coastal sites in Hainan Island was examined using morphological, cytometric, and genomic approaches. Three priority conservation areas are proposed to preserve extant genetic diversity and maintain habitat connectivity. ABSTRACT Acrostichum aureum across nine coastal sites in Hainan Island was examined using morphological,

Squamate ventricular cardiomyocytes: Ploidy, proliferation, and heart muscle cell size in the leopard gecko (Eublepharis macularius)

Developmental Dynamics, EarlyView.
Abstract Background While heart function is broadly conserved across vertebrates, the cellular phenotype of muscle cells (cardiomyocytes) varies across taxa and throughout ontogeny. Emerging evidence suggests that some attributes may correlate with the capacity for spontaneous cardiomyocyte replacement following injury.

Effect of Ploidy in Photoreactivation.

Experimental Biology and Medicine, 1952
SummaryThe survival fractions of diploid and haploid strains of S. cerevisiae after ultraviolet irradiation (2537 A.U.) have been obtained, compared, and modified by photoreactivation following the initial irradiation. The haploid survival follows a sigmoid curve and is smaller than the diploid at the same dose.

CATECHOLAMINE SECRETION AND PLOIDY IN PHAEOCHROMOCYTOMA

International Journal of Clinical Practice, 2000
SUMMARYThe aim was to evaluate 24 hr urine catecholamine, HMMA and HVA excretion in relation to ploidy in phaeochromocytoma. Data from five diploid and nine tetraploid tumours showed a significant reduction in urine noradrenaline (p=0.02) and HMMA (p=0.03) in diploid tumours but no difference in adrenaline, dopamine and HVA excretion using the Mann ...

Loss of the Y Chromosome in Oral Potentially Premalignant Disorders Predicts Malignant Progression: An Integrative Cross‐Species Multi‐Cohort Bioinformatic Study

Head &Neck, EarlyView.
ABSTRACT Background The loss of the Y chromosome (LOY) and the extreme down‐regulation of Y chromosome gene expression (EDY) are frequently observed in oral squamous cell carcinoma (OSCC). However, their roles in oral potentially malignant disorders (OPMDs) are unclear.

Malignant Transformation of Oral Leukoplakia and Proliferative Verrucous Leukoplakia and Its Biomarker Predictors: A Systematic Umbrella Review

Head &Neck, EarlyView.
ABSTRACT Background Oral leukoplakia (OL) represents the most common oral potentially malignant disorder globally, with highly variable reported malignant transformation (MT) rates creating challenges for evidence‐based clinical management. Objective To systematically synthesize evidence on MT prevalence in OL and evaluate potential predictive ...
