One question: does the server use only text, or also figures? I imagine one uploads an entire manuscript, figures included, but I also imagine that the algorithm cannot critically evaluate figures, only the authors' interpretation of the figures/results. Is that the case?

Bonus: RNA editing of CaV1.3_43S also alters drug sensitivityβ€”increasing responsiveness to DHP Ca²⁺ channel blockers.

⚑ Editing is not randomβ€”it can reshape both physiology and pharmacology.

Why does this matter?

Neurons expressing CaV1.3_43S are at risk of Ca²⁺ toxicity, e.g. in Parkinson’s, Alzheimer’s, and spinal cord injury.

RNA editing acts as a neuroprotective brake by dampening excessive Ca²⁺ influx.

Editing of CaV1.3_43S produces loss-of-function changes:

πŸ‘‰ ↓ current density

πŸ‘‰ ↑ activation threshold

πŸ‘‰ Depolarized current window

Together, this converts the β€œshort” splice variants into β€œlong-like” channels, reducing Ca²⁺ overload.

CaV1.3 has long (CaV1.3L) and short (CaV1.3_43S) splice variants.

πŸ‘‰ We found that the short variant undergoes ~3x more RNA editing at its IQ domain (a crucial #calmodulin binding site in the C-terminus) than the long form.

This creates multiple edited isoforms with distinct channel properties.

We uncover an unexpected synergy between RNA editing & alternative splicing in the CaV1.3 calcium channel. This mechanism fine-tunes neuronal Ca²⁺ entry & may protect against excitotoxicity.

The husband is a sociopath. However, it sounds like they only dated for 6 months before getting married. Kinda short, I think?

Also, getting pregnant to make him "feel secure"...? What does that even mean?
