Changes in the baroreflex during pregnancy in conscious dogs: heart rate and hormonal responses.

abstract：:We recently reported that bone morphogenetic proteins (BMPs) 2 and 4 can stimulate FSHbeta-subunit (Fshb) transcription alone and in synergy with activins. We further showed that BMP2 signals via the BMP type IA receptor (or activin receptor-like kinase 3) to mediate its effects. However, the intracellular mechanisms ...
