The purpose of this work is to study the effect of smilagenin on the mRNA stability of muscarinic receptor subtype 1 (M(1); m1 mRNA) in aged rat brains and its significance in improving memory. The Y-maze avoidance task showed that
This work studied the role of cyclic AMP responsive element binding protein (CREB) in the up-regulation of M(1) muscarinic acetylcholine receptor (M(1) receptor) density by sarsasapogenin (ZMS) in CHO cells transfected with M(1) receptor gene (CHOm1 cells). During cell aging

We investigated the effect of tigogenin on adipocytic and osteoblastic differentiation in mouse bone marrow stromal cells (BMSCs). Tigogenin enhanced the proliferation of BMSCs significantly. Tigogenin treatment reduced the adipogenic induction of lipid accumulation, visfatin secretion, and the expressions of

We conducted our study to assess the antiproliferative and proapoptotic potential of hecogenin and tigogenin, two saponins which are structurally similar to diosgenin. We particularly focused our attention on mitogen-activated protein kinase (MAPK) activation in relation to apoptosis but also

One new (Sarsasapogenin O) and seven known steroids were isolated from the roots of Asparagus officinalis L. Their structures were elucidated on the basis of spectroscopic analysis, including various 2D-NMR techniques, hydrolysis, and by comparison of spectral data of known
