Labβs 1st preprint!
Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) donβt menstruate.
@cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation.
He is on the job market!

We built the first transgenic model of menstruation in mice.
We used it to uncover how the endometrium organizes and sheds during menstruation. π§ͺ

This is clever π
TMC1/2 activation by mechanical forces in cell lines is compelling! The hearing field has struggled with membrane expression of these proteins, but a CRISPR screen offers a clever workaround. Excited to see if another lab can replicate these findings.

www.cell.com/neuron/fullt...
Human TMC1 and TMC2 are mechanically gated ion channels
Fu et al. showed that point mutations in MmTMC1/2 are localized in plasma membrane, and knockdown of UROD, RGP1, or ARL1 promotes plasma membrane localization of HsTMC1/2 in heterologous cells. HsTMC1/2 are activated by mechanical stimuli and function as pore-forming ion channels, supporting their roles as mechanotransduction channels in hair cells.
