Insects, 2021 Small heat shock proteins (sHSPs) are members of the heat shock protein (HSP) family that play an important role in temperature stress, and heat shock factors (HSFs) are transcriptional activators that regulate HSP expression. Cotesia chilonis, the major

Identification and function of human cytomegalovirus microRNAs [PDF]
, 2008 microRNAs are an extensive class of non-coding genes that regulate gene expression through post-transcriptional repression. These small RNAs are evolutionarily conserved and are likely to be a basic mechanism of gene regulation present within most ...

Manipulating chromatin architecture in C. elegans
Epigenetics & Chromatin, 2022 Background Nucleosome-mediated chromatin compaction has a direct effect on the accessibility of trans-acting activators and repressors to DNA targets and serves as a primary regulatory agent of genetic expression. Understanding the nature and dynamics of

Mechanisms of stimulation of SAGA-mediated nucleosome acetylation by a transcriptional activator
Biochemistry and Biophysics Reports, 2021 Eukaryotic gene expression requires the coordination of multiple factors to overcome the repressive nature of chromatin. However, the mechanistic details of this coordination are not well understood.

Posttranscriptional trans-activation in cauliflower mosaic virus
Cell, 1989 The ability of plant cells to translate dicistronic mRNAs that mimic a segment of the polycistronic 35S RNA from cauliflower mosaic virus has been tested. The chloramphenicol acetyltransferase and beta-glucuronidase open reading frames (ORFs) were fused in-frame to the second viral cistron (ORF I).

Lineage-specific Gene Expression in the Sea Urchin Embryo [PDF]
, 1985 Within a few days of fertilization, the sea urchin embryo develops into a small differentiated organism consisting of about 1800 cells and capable of feeding, swimming, and the further ontogenic transformations required in the succeeding weeks of larval ...

Metabolomic and physiological analysis of bud differentiation in dense apple (Malus×domestica Borkh.) orchards following thinning and reshaping [PDF]
PeerJBackground In China, a majority of apple orchards were initially planted under arboriculture. The branch number increases, causing a deterioration of the canopy light conditions as the trees age.

Lineage and fate of each blastomere of the eight-cell sea urchin embryo [PDF]
, 1987 A fluoresceinated lineage tracer was injected into individual blastomeres of eight-cell sea urchin (Strongylocentrotus purpuratus) embryos, and the location of the progeny of each blastomere was determined in the fully developed pluteus.
