Fragility of ER homeostatic regulation underlies haploid instability in human somatic cells.

Mammalian somatic cells are generally unstable in the haploid state, resulting in haploid-to-diploid conversion within a short time frame. However, cellular and molecular principles that limit the sustainability of somatic haploidy remain unknown. In this study, we found the haploidy-linked vulnerability to endoplasmic reticulum (ER) stress as a critical cause of haploid intolerance in human somatic cells.

Genome-wide characterization of Histone gene family and expression profiling during microspore development in radish (Raphanus sativus L.).

Histone, a predominant protein component of chromatin, participates in DNA packaging and transcriptional regulation. However, the available information of Histone gene family is limited in radish. In this study, a total of 42 Histone gene family members were identified from the radish genome.
