    Article Title: L-type voltage-gated Ca 2+ channel Ca V 1.2 regulates chondrogenesis during limb development
    Article Snippet: .. For immunological staining on histological sections, the following antibodies were used as described previously ( 54 ): Mouse anti-Collagen 2A1 (1:100; DSHB, II-6B3), rabbit anti-pH3 (1:1,000; Millipore, 06-570), rabbit anticleaved caspase-3 (1:300; Cell Signaling, #9661), rabbit anti-Ca v 1.2 (1:200; Alomone Laboratories, ACC-003), rabbit anti-Sox9 (1:500; Millipore, AB5535), rabbit anti-pSmad1/5 (1:300, Cell Signaling, #9516), and mouse anti-NFATc1 (1:25; Santa Cruz, sc-7294). ..

    Figure Lengend Snippet: a CYFIP1 RNA immunoprecipitation (RNA-IP) from DIV 3 WT cortical neurons. Histogram showing relative enrichment of the mRNAs over the non-specific IgG, measured by RT-qPCR of the eluate. The values were normalized for the input and mHprt1 mRNA and expressed as fold change over the non-specific IgG of each mRNA ( n = 4 embryos; mean ± SEM; One-Way ANOVA p < 0.0001; mMap1b mRNA p = 0.0390, mCacna1c mRNA p = 0.0054, mCacna1e mRNA p = 0.0078, mCacna1i mRNA p = 0.0009, mCacng2 mRNA p = 0.9997, mCacnb3 mRNA p = 0.9983). b Total mRNA levels of the Ca 2+ channels in DIV 3 WT and Cyfip1 +/- cortical neurons.

    CYFIP1, potentially interacting with the RNA binding proteins HuD and HuR (previously identified as CYFIP1 interactors), is implicated in regulating the mRNA stability of calcium channel subunits Cacna1c , Cacna1e and Cacna1i . In Cyfip1 +/- neurons, reduced CYFIP1 levels result in a decrease protein abundance of the regulated calcium channel subunits, consequently leading to a decrease in intracellular and mitochondrial calcium concentration. Low levels of calcium ions may affect mitochondria polarity and motility, both of which we found impaired in Cyfip1 +/- axons. The decreased calcium concentration and the mitochondrial defects concur in reducing axonal growth observed in Cyfip1 +/- neurons. By restoring the intracellular calcium homeostasis, both the axonal growth and mitochondrial defects are rescued. Created in BioRender. https://BioRender.com/xquv8cy .
