... Abstract: Given strong evidence implicating an important role of altered microRNA expression in cancer initiation and progression, the genes responsible for microRNA biogenesis may also play a role in tumorigenesis. Exportin-5 (XPO5) is responsible for exporting pre-miRNAs through the nuclear membra ...

When the chemical binds to the receptor, a signal is sent to the brain where it is interpreted as a particular taste—sour, bitter, sweet, salty or umami. Recently, the gene that codes for the receptor that binds PTC was identifi ...

The absence of the 23-kb fragment after hybridization with exon 7 or exon 8 suggested either a deletion of the relevant regions of the RHCE gene in the DC- gene complex or the presence of an unusual band comigrating with the 19 kb D-specific fragment. The exon ...

Some of these anastomosis groups are further subdivided based on pathogenicity (AG-1, AG-2), colony morphology (AG-1), thiamine requirement (AG-2, AG-9), and/or DNA homology (AG-4, AG-6) into intraspecific groups (ISG) (11). The ISG is derived by combining anastomosis group affiliation w ...

In this study, we show that the zygote remains relatively quiescent and that the embryo can undergo several divisions in the absence of de novo transcription, thus relying on deposited maternal products. By contrast, the endosperm strictly requires de novo transcrip ...

Epigenomics

Epigenomics is the study of the complete set of epigenetic modifications on the genetic material of a cell, known as the epigenome. The field is analogous to genomics and proteomics, which are the study of the genome and proteome of a cell (Russell 2010 p. 217 & 230). Epigenetic modifications are reversible modifications on a cell’s DNA or histones that affect gene expression without altering the DNA sequence (Russell 2010 p. 475). Two of the most characterized epigenetic modifications are DNA methylation and histone modification. Epigenetic modifications play an important role in gene expression and regulation, and are involved in numerous cellular processes such as in differentiation/development and tumorigenesis (Russell 2010 p. 597). The study of epigenetics on a global level has been made possible only recently through the adaptation of genomic high-throughput assays (Laird 2010) and.
