The tRNA methyltransferase 1 (TRMT1) enzyme catalyzes the N2,N2-dimethylguanosine (m2,2G) modification in tRNAs. Intriguingly, vertebrates encode an additional tRNA methyltransferase 1-like (TRMT1L) paralog. Here, we use a comprehensive tRNA sequencing approach to decipher targets of human TRMT1 and TRMT1L.

The involvement of Loose Plant Architecture 1 (LPA1) in regulating plant growth and leaf angle has been previously demonstrated. However, the fundamental genetic background remains unidentified. To further understand the tissue expression profile of the NtLPA1 gene, an overexpression vector (pBI121-NtLPA1) was developed and employed to modify tobacco using the leaf disc method genetically.

Background: Neurodegenerative diseases are a heterogeneous group of illnesses. Differences across patients exist in the underlying biological drivers of disease. Furthermore, cross-diagnostic disease mechanisms exist, and different pathologies often co-occur in the brain.
View Article and Find Full Text PDFBackground: The earliest recognized biomarker of AD is deposition of Aβ amyloid that leads to formation of plaques and may, over time, trigger or at least be followed by gliosis/neuroinflammation and neurofibrillary tangles, accompanied by neurodegenerative changes including neuronal and synaptic loss. We have previously reported that semaphorin 4D (SEMA4D), the major ligand of plexin B receptors expressed on astrocytes, is upregulated in diseased neurons during progression of AD and Huntington's disease (HD). Binding of SEMA4D to PLXNB receptors triggers astrocyte reactivity, leading to loss of neuroprotective homeostatic functions, including downregulation of glutamate and glucose transporters (doi:10.
