Progression through G₁ phase of the cell cycle is controlled largely by growth factors in early G₁ and by nutrients in late G₁ indicating sufficient raw material for cell division. We previously mapped a late G₁ cell cycle checkpoint for lipids upstream from a mammalian target of rapamycin complex 1 (mTORC1)-mediated checkpoint and downstream from a mid-G₁ checkpoint known as the Restriction point. We therefore investigated a role for lipids in progression through late G₁ into S-phase. Quiescent BJ-hTERT human fibroblasts primed back into G1 with FBS treatment, were treated with a mixture of …
