Is paroxetine-induced reduction of sexual incentive motivation in female rats modified by 5-HT1B or 5-HT2C antagonists?
The effects of paroxetine seen in female rats are similar to those observed in women, suggesting that disturbances of sexual incentive motivation in rats are predictive of sexual dysfunction in women. The 5-HT(1B) and 5-HT(2C) receptors do not seem to be of any importance for paroxetine's inhibitory effect.
In aggregate, these studies support the notion that TGF-beta plays an important role in both bone-and lung metastases of basal-like breast cancer, and that inhibiting TGF-beta signaling results in a therapeutic effect independently of the tissue-tropism of the metastatic cells. Targeting the TGF-beta pathway holds promise as a novel therapeutic approach for metastatic basal-like breast cancer.
