Natl. Acad. Sci. USA</i> 118, e2019756118. 2021; https://doi.org/10. 1073/pnas.2019756118 and <i>Research</i> 6, 0139, 2023; https://doi.org/10.34133/research.0139). Ordinarily, the clock proteinPERIOD (PER) forms foci close to the inner nuclear membrane in the circadian clock's repression phase. The size, number, and location of foci near the nuclear membrane oscillate with a 24-h rhythm. When LBR was absent the foci did not form. The PER foci bring <i>per</i> and other clock genes close to the nuclear envelope, where their transcription is silenced. Then, in the circadian clock's activation phase, the PER protein gradually gets degraded and the foci disappear. The clock genes, including <i>per</i>, relocate to the nucleus interior where they resume transcription. Rhythmic re-positioning of clock genes between nucleus periphery and interior, correlates with their repression and activation in the circadian cycle. Absence of LBR disrupted this rhythm. Phosphorylation of PER promoted the formation of foci whereas dephosphorylation by protein phosphatase 2A causedthem to disappear. LBR promoted focus formation by destabilizing the catalytic subunit of protein phosphatase 2A. The <i>lbr</i> gene is no stranger to this journal. The first hint that vertebrate LBR is also a sterol biosynthesis enzyme, specifically, a sterol C14 reductase, was reported here (<i>J. Genet</i>. 73, 33-41, 1994; https://www.ias.ac.in/article/fulltext/jgen/073/01/0033-0041). Mutations in the human <i>Lbr</i> gene cause a range of phenotypes--from the relatively benign Pelger-Huet anomaly to the perinatally lethal Greenberg skeletal dysplasia.Drosophila, like all insects, is a sterol auxotroph. The fly orthologue of vertebrate <i>lbr</i> genes encodes a protein (dLBR) that shares several properties with vertebrate LBR proteins, with one notable exception. While human LBR complemented theyeast Saccharomyces cerevisiae erg24 mutant which lacks sterol C14 reductase activity, dLBR did not (<i>J. Cell. Sci. 117</i>, 2015-28, 2004; https://doi.org/10.1242/jcs.01052). Despite not possessing sterol reductase activity, dLBR retains significant sequence homology with vertebrate LBRs which have this activity. An undergraduate summer trainee in my laboratory obtained early (unpublished) evidence that dLBR lost sterol reductase activity during evolution. She transferred adult drosophila flies to vials containing a medium made of agar, dextrose, and dried and powdered mycelium of the filamentous fungus <i>Neurospora crassa</i>. On medium made with wild-type mycelium, theflies mated, laid eggs, hatched larvae, and developed pupae which eclosed progeny adult flies.

A promising gene-silencing approach for gene therapy is DNA interference (DNAi), a sequence that is complementary to the promoter region of a target gene. To confer resistance to nuclease digestion, several modifications such as methylphosphonate or phosphorothioate have been proposed, wherein a nonbridging oxygen atom in the oligonucleotide phosphate backbone is replaced by sulphur. The aim of the present study was to assess the effectiveness of the DNAi molecule with phosphorothioate (PS) and without phosphorothioate (WPS) modification for inhibition of myostatin gene expression in mice.

This gene plays a role in the differentiation of intestinal epithelial cells, and its expression decreases in a number of cell lines derived from CRC, which suggests that a lack of <i>CDX1</i> expression is a risk factor for the development of colorectal carcinoma. Therefore, the methylated DNA amounts of <i>CDX1</i> gene in stool samples were investigated as a noninvasive method for the detection of CRC. In the present study, the methylation of <i>CDX1</i> gene promoter region was assessed in stool samples of 50 CRC patients and 50 healthy individuals by MethyLight PCR using two primers and a Taq Man probe, which was completely specifically designed for fully methylated DNA of the gene promoter region.
