A unique form of regulation has been observed in the unfolded protein response of S. pombe, along with a novel mechanism of post-transcriptional mRNA processing.

Genome-wide measurements on mouse liver cells show that transcription, and a particular key transcription factor, have a smaller than expected influence on the mouse circadian system.
Chronic and excessive inflammation can lead to exhaustion of the supply of hematopoietic stem cells and to myeloid malignancies in mice, mimicking important aspects of the myelodysplastic syndrome found in humans.

A small RNA molecule called miR-124 controls pheromone production and sexual behaviour in Drosophila by regulating sex-specific gene expression in males.
The eye produces a protein that inhibits the growth of blood vessels in the deep retina, which includes the photoreceptor layer, and disruption of this process can lead to blindness.

C. elegans equalizes the expression of X-chromosome genes between the sexes by reducing the recruitment of RNA polymerase II to promoters of X-linked genes in hermaphrodites, using a chromosome-restructuring complex called condensin.

Reduced expression of MYBL2 contributes to malignancies of the blood by permitting uncontrolled expansion of blood cell progenitors, implying a tumor suppressor function for this gene.
While intact mir-17-92 acts as a potent oncogene in a mouse model of Burkitt’s lymphoma, one of the six mir-17-92 components antagonizes its oncogenic cooperation with c-Myc by promoting c-Myc-induced apoptosis.
