🔥 📣 This is probably bad timing, with all the political chaos in Israel, but we're looking for a PhD student to continue a grad student's project on mRNA transfer through tunneling nanotubes.
Start date ~Jan 2024.
We are looking for someone interested in deciphering the molecular mechanism of mRNA transfer, by performing a CRISPR/siRNA/drug screen, and using molecular biology & biochemistry tools.

Wow! 💥 🔥 🔥 🔥
This is so cool!
In this paper,
"Spatially resolved single-cell translatomics at molecular resolution", they used a tri-probe FISH system combined with in situ amplification and in situ sequencing to detect multiplex translating mRNAs at sub-cellular resolution in cell culture (981 genes) and mouse brain tissue slices (5413 genes!).

Interesting paper from Tatjana Trcek lab.
She & her team looked at fly #GermGranules nucleation and, well... the title says it all:

"Proteins rather than mRNAs regulate nucleation and persistence of Oskar germ granules in Drosophila "

#mRNA #mRNALocalization #Drosophila #LLPS

It is also her 1st paper as #NewPI so congrats are in order.

Wow!
looks like super awesome method from Long Cai lab

"High-resolution spatial multi-omics reveals cell-type specific nuclear compartments"

They did mRNA #seqFISH+ (1200 genes, 17K introns), DNA seqFISH+ (100K loci) and #immunofluorescence (up to 65 antibodies) all in the same experiment!
200+ rounds of #imaging! That's incredible.

New pre-print from Voula Mili lab.
she suggests that mRNA localization and translation rate determine the localization of a protein which is found both in nucleus and cytoplasm.
I'll need to find time to dive it and read in detail.

Wow, from the abstract this paper from Christine Mayr lab looks super interesting!

I tried the original protocol a few years ago and didn't work well. inconsistent labeling (some good, some poor) and wasn't *that* cheap.
but maybe time to re-visit this protocol with this improved version:
