sgRNA constructs and gene expressing codon optimized (OPT) plasmid constructs sgRNA control and constructs against CBS and L2HGDH were designed targeting GTATTACTGATATTGGTGGG (sgControl) (#230080, Addgene), GGAGCAGACAACCTACGAGG (sg CBS -1) (#230081, Addgene), TGGCAGTGCTGGCAGCACGG (sg CBS -2) (#230082, Addgene), GATATAGTCATCGTTGGTGG (sg L2HGDH -1) (#230083, Addgene), and CACCAGACTGGACATAACAG (sg L2HGDH -2) (#230084, Addgene) and constructed in lentiCRISPR v2-Blast (#83480, Addgene) for Blasticidin selection at a final concentration of 5 g/ml

To evaluate this hypothesis, we inhibited the NGF/TrkA pathway by using an anti-NGF antibody, which does not permeate the BBB, as a pretreatment before the i.p
To use, simply administer one spray into each nostril about 30 to 60 minutes before sexual activity
However, taking on an empty stomach still enhances cellular uptake
