Gene/genome dosage balance is an essential evolutionary mechanism for organisms to ensure a normal function, but the underlying causes of dosage-imbalance regulation remain poorly understood.

DOSAGE COMPENSATION: REGULATION OF SEX CHROMOSOME GENE EXPRESSION
Dosage compensation is observed in various taxa of organisms with heteromorphic sex chromosomes. Dosage compensation mechanisms are thought to have arisen to eliminate differences in gene dosage between sexes that appeared in the course of sex chromosome

A Quantitative Perspective of Alpha-Synuclein Dynamics – Why Numbers Matter
The function of synapses depends on spatially and temporally controlled molecular interactions between synaptic components that can be described in terms of copy numbers, binding affinities, and diffusion properties.

Gene Dosage and Gene Duplicability [PDF]
Abstract The evolutionary process leading to the fixation of newly duplicated genes is not well understood. It was recently proposed that the fixation of duplicate genes is frequently driven by positive selection for increased gene dosage (i.e., the gene dosage hypothesis), because haploinsufficient genes were reported to have more ...

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

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.

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