So regrowth of cochlear hair cells is not only associated with notch1 inhibition but also decreased levels of the genes
Hes1, Hes5, Hey1, HeyL, and Jagged1.
"Expression changes of genes in the Notch pathway were measured using immunostaining and in situ hybridization, with most changes observed in the apical one-third of the cochlea where the majority of HC regeneration occurs. Expression of the Notch target genes Hes1, Hes5, Hey1, HeyL, and Jagged1 were decreased."

Hes1:
"Treatment with curcumin resulted in downregulation of Notch1 and its downstream target, Hes1"

Hes5:
"Curcumin, isolated from Turmeric, inhibits the development of pulmonary arterial hypertension via down regulation of Notch3 and its target gene Hes-5"

Hey1:
Compared with control, there was a reduction of Notch-1, Hes-1, Hey-1 and Hey-2 mRNA levels after curcumin
treatment, suggesting that curcumin resulted in the transcriptional inactivation of Notch-1 signaling pathway"

HeyL:
No data, yet.
Jagged1:
"Our studies demonstrate that curcumin inhibits the expression of Jagged-1 and the Notch-1 receptor. Curcumin also inhibits γ-secretase complex proteins, thereby inhibiting cleavage of the Notch receptor."
