Studies of 1-deoxynojirimycin measured 11 outcomes, among them wnt/β-catenin signaling, osteoclast differentiation and osteogenic differentiation.

Wnt/β-catenin signaling

upin cells1

1 study
  1. 1-deoxynojirimycin activates wnt/β-catenin signaling in cells (through direct binding to LRP5).

    “thus promoting the Wnt/β‐catenin signaling axis to activate the transcription of osteogenesis‐related genes in osteoblasts.”

1 study
  1. 1-deoxynojirimycin showed no clear effect on osteoclast differentiation in cells.

    “DNJ promoted osteogenic differentiation and matrix mineralization of primary BMSCs and osteoblasts without affecting primary osteoclast differentiation.”

Spatial memory

upin mice1

1 study
  1. 1-deoxynojirimycin improves spatial memory in SAMP8 mice.

    “Our results indicated that DNJ treatment improved these changes, and the 160-mg/kg/day DNJ group revealed more significant alleviation.”
