PROZA-M experiment results as well the proposal of a new spin program
with the use of a polarized proton beam are presented. Significant
asymmetries were observed in inclusive $\pi^0$ production. The new
program proposes to study a wealth of single- and double-spin
observables in various reactions using longitudinally and transversely
proton beams at U70. The main goal is to define gluon contribution to
nucleon spin by measuring double-spin asymmetry in charmonium
