Polycomb-mediated repression of paternal chromosomes maintains haploid dosage in diploid embryos of Marchantia

open access: yeseLife, 2022
Complex mechanisms regulate gene dosage throughout eukaryotic life cycles. Mechanisms controlling gene dosage have been extensively studied in animals, however it is unknown how generalizable these mechanisms are to diverse eukaryotes.

Plasmodium Reproduction, Cell Size, and Transcription: How to Cope With Increasing DNA Content?

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Plasmodium, the unicellular parasite that causes malaria, evolved a highly unusual mode of reproduction. During its complex life cycle, invasive or transmissive stages alternate with proliferating stages, where a single parasite can produce tens of ...

Photoreactivation and Gene Dosage in Yeast [PDF]

open access: yesJournal of Bacteriology, 1972
The amount of photoreactivating enzyme in tetraploid cells of Saccharomyces cerevisiae and the ability of the cells to be photoreactivated after ultraviolet irradiation are directly proportional to the number of genes per cell involved in the synthesis of photoreactivating enzyme.

Identificación de portadoras de distrofia muscular de Duchenne y Becker (DMD/DMB) mediante análisis de dosis génica y polimorfismos de ADN

open access: yesBiomédica: revista del Instituto Nacional de Salud, 2000
Se identificaron 7 mujeres portadoras y 15 no portadoras de deleción en 16 familias con distrofia muscular de Duchenne o de Becker (DMDIDMB) mediante PCR multiplex cuantitativa y análisis de dosis génica. Los afectados con DMDIDMB mostraron deleciones en

Consequences of Chromosome Loss: Why Do Cells Need Each Chromosome Twice?

open access: yesCells, 2022
Aneuploidy is a cellular state with an unbalanced chromosome number that deviates from the usual euploid status. During evolution, elaborate cellular mechanisms have evolved to maintain the correct chromosome content over generations.

Gene dosage analysis in Azotobacter vinelandii. [PDF]

open access: yesGenetics, 1992
Abstract For more than a decade, Azotobacter vinelandii has been considered a polyploid bacterium on the basis of physical studies of chromosome size and DNA content per cell. However, as described in the present work, many genetic operations can be performed in A. vinelandii without the constraints expected in a polyploid bacterium: (i)

Hnf1b haploinsufficiency differentially affects developmental target genes in a new renal cysts and diabetes mouse model

open access: yesDisease Models & Mechanisms, 2021
Heterozygous mutations in HNF1B cause the complex syndrome renal cysts and diabetes (RCAD), characterized by developmental abnormalities of the kidneys, genital tracts and pancreas, and a variety of renal, pancreas and liver dysfunctions.

DNA Methylation Rebalances Gene Dosage after Mammalian Gene Duplications [PDF]

open access: yesMolecular Biology and Evolution, 2011
Although gene duplication plays a major role in organismal evolution, it may also lead to gene dosage imbalance, thereby having an immediate adverse effect on an organism's fitness. Investigating the evolution of the expression patterns of genes that duplicated after the divergence of rodents and primates, we confirm that adaptive evolution has been ...
