  • Prostate cancer depends on the signalling pathways of the androgen receptor (AR).
  • Although great effort has been made to specifically target tumour cells that express AR, the majority of individuals with prostate cancer experienced failure from these treatments.
  • Here, we use in vivo tests and mouse models to show that deletion of AR in stromal sonic-hedgehog Gli1-lineage cells reduces prostate epithelial oncogenesis and tumour formation.
  • Single-cell RNA sequencing and other analyses revealed a significant rise in insulin-like growth factor (IGF) binding protein 3 expression in AR-deficient stroma through attenuated AR (androgen)suppression on Sp1-regulated transcription.
  • This further inhibits IGF1-induced Wnt/-catenin activation in neighbouring basal epithelial cells and suppresses the growth and development of tumours in these cells. Mice lacking in stromal AR can regain IGF1-induced oncogenic growth in epithelial organoids.

Georgia [21]

Answer:

Explanation:

In summary, it takes six turns of the Calvin cycle to fix six carbon atoms from CO2. These six turns require energy input from 12 ATP molecules and 12 NADPH molecules in the reduction step and 6 ATP molecules in the regeneration step.
