...and Amon 2011). Disorders like Down syndrome, caused by the triplication of Chromosome 21, and Cri du chat syndrome, caused by the deletion of a region of Chromosome 5p, affect the expression of hundreds of genes and perturb normal development. 8p syndrome, caused by rearrangements affecting the p arm...

This noncanonical H3K27me3 enrichment resembles the pattern observed in female Drosophila GSCs, in which H3K27me3 is detectable at both inactive and active gene loci (DeLuca et al. 2020).In contrast, in CySC-like cells, H3K27me3 is most...

Through functional enrichment analysis, we show that these conserved X-linked genes...

By critically examining both established tools and emerging techniques such as editing, synthetic chromosomes, and high-resolution imaging, we provide a practical framework for investigators seeking to uncover direct regulators of specific genes. Our goal is to guide the design of experiments...

However, our study reveals a systematic failure of both technologies to sequence and assemble specific exons of Drosophila melanogaster genes, indicating an overlooked limitation. Namely, multiple Y-linked exons are nearly or completely absent from raw...

...and 5 kb (Colby and Williams 1993). The 5-kb repeat unit has a 242-bp insert between H1 and H3 genes. These variants are present in a number of Drosophila species, indicating that their origin predates the speciation event (Strausbaugh and Weinberg 1982). Figure 3B shows the distribution of 5- and 4...
