Blockade of autophagy at this step would also result in an increased number of autophagosomes.
Blockade of any step in the chlorophyll biosynthesis pathway will cause a decline in Chl content.
In the adrenal and gonadal glands, the loss of DHEA and DHEAS is attributed to a synthetic blockade of the second step of the enzyme P450c17, again induced by inflammatory cytokines such as IL1β and TNF.
The non-progesterone-like effect of RU486 may be mediated through a pathway that is different from the progesterone-mediated pathway, or it is the result of a blockade of certain critical step(s) in the progesterone-mediated pathway.
As suggested by previous work from our laboratory and from others, under circumstances in which the intrarenal RAS is activated, such as in DM, blockade of additional steps in the RAS activation cascade should enhance efferent arteriolar vasodilatation (4).
The blockade of this cascade is believed to attenuate signs of physical opiate withdrawal.
Blockade of this pathway reversed primary pulmonary hypertension and improved survival.
According to these findings, we believe that blockade of this enzyme may be essential for preventing the disease.
Blockade of this pathway represents a novel therapeutic approach for treatment of sickle disease.
