The phrase "action is postulated to" is correct and usable in written English.
It can be used in contexts where you are discussing theories, hypotheses, or assumptions about actions or behaviors.
Example: "In this study, it is suggested that action is postulated to lead to significant changes in behavior."
Alternatives: "action is assumed to" or "action is believed to".
o-OPN has been shown to ameliorate DSS-induced colitis (da Silva et al, 2009) and alcohol-induced liver damage (Ge et al, 2013), but the mechanism of both these actions are postulated to be within the digestive system.
The mechanism of action of PDT is postulated to be short-term choriocapillaris hypoperfusion and long-term choroidal vascular remodeling, leading to reduction in choroidal congestion, vascular hyperpermeability, and extravascular leakage [ 8].
Thus, in untreated maternal thyroid disorders, alterations in TH action within the placental compartment is postulated to contribute to the pathophysiology of adverse outcomes associated with malplacentation (14), such as miscarriages, preeclampsia, abruption, intrauterine growth restriction, postpartum hemorrhage, and stillbirths.
The primary mechanism of action of phentermine in obesity treatment is postulated to be appetite suppression; however, other central nervous system (CNS) actions, or metabolic effects, may also be involved [9].
The activation of the predominant circulating TH, T4, into the active ligand, T3, by deiodinase type 2 in villous trophoblast is postulated to provide for local TH action.
Iniparib is postulated to have a different mechanism of action and may not be a bona fide PARP inhibitor.
Obesity-associated carcinogenesis is postulated to be mediated through the proliferative actions of insulin and the insulin-like growth factor (IGF) family.
Based on these findings, exposure to unidentified environmental causes is postulated to be increasing, with observed birth cohort effects attributed to early action of such exposures.
At the molecular level, the reward signal is postulated to be a neurotransmitter such as dopamine, which exerts a global modulatory action on prefrontal synaptic efficacies, either via volume transmission or via targeted synaptic triads.
