Blau's group found that the daily changes in Rho1 activity are controlled by rhythms in
transcription of a gene very similar to human Puratrophin - 1.

He adds that the abundance
of transcripts that overlap each
gene suggests that the
very term «
gene» should mean something different inside the cell nucleus, where
transcription takes place, than outside
of it, where finished proteins go.
This is believed to be true given the results
of previous RNA - seq experiments (1, 4, 5) along with a belief that the odds are
very low that Cas9 would have an off - target that lands in the promoter
of another
gene, thereby driving aberrant
transcription.
A third, more basic, project in our lab concerns the
transcription and splicing
of very large mammalian
genes.
We have recently shown that
transcription proceeds rapidly and efficiently through these
genes and that splicing
of the
very long introns found in such
genes is also efficient.
A few receptor
genes have more than 8 different isoforms (38 VRs and 10 ORs), however in most
of these cases this is due to the presence
of several
transcription start sites (TSS) or exons that differ in length by just a few nucleotides, so several
of the final transcripts differ only
very slightly (Figure S7B).
The algorithm can also accurately predict the effect
of mutations on
gene expression even for
very low - affinity binding sites — regions in the genome where
transcription factors bind to DNA, but do so in hard - to - detect ways.
The recent recognition that de novo lipogenesis might have relevance for lipid homeostasis in skeletal muscle stems from the realization that Sterol regulatory element binding protein - 1c (SREBP - 1c), a member
of the family
of transcription factors that regulate the expression
of genes involved in lipid storage in liver and adipose tissue, is also present in skeletal muscle at a level close to that observed in the liver, 41,42... [M] ost fascinating are the
very recent demonstrations that glucose alone (in the absence
of insulin) can stimulate de novo lipogenesis in skeletal muscle cells....
