17353442 Kajimoto H, Hashimoto K, Bonnet SN, Haromy A, Harry G, Moudgil R, Nakanishi T, Rebeyka I, Thebaud B, Michelakis ED, Archer SL: Oxygen activates the Rho/Rho-kinase pathway and induces RhoB and ROCK-1 expression in human and rabbit ductus arteriosus by increasing mitochondria-derived reactive oxygen species: a newly recognized mechanism for sustaining ductal constriction. Circulation. 2007 Apr 3;115(13):1777-88. Epub 2007 Mar 12.

Activation of Rho-kinase in DA smooth muscle cells is initiated by a PO2-dependent, rotenone-sensitive increase in mitochondrion-derived reactive O2 species.

In accordance with this, treatment of neuronal cultures with cytochalasin D, an actin-depolymerizing drug, or with the Rho-kinase inhibitor Y27632, or overexpression of Tiam1, a guanosine nucleotide exchange factor for Rac, reverts the inhibitory effect of rotenone on axon formation.

Cold causes translocation of alpha2C-ARs from the trans-Golgi to the plasma membrane, mediated by cold-induced activation of RhoA and Rho kinase.
The inhibitor of mitochondrial complex I rotenone (10 micromol/l), the antioxidant N-acetylcysteine (NAC; 20 mmol/l), or the cell-permeable mimic of superoxide dismutase MnTMPyP (50 micromol/l) did not affect vasoconstriction to alpha2-AR stimulation (UK-14304) at 37 degrees C but dramatically inhibited the response at 28 degrees C.

Here we show that TPPII translocated into the nucleus in a p160-ROCK-dependent fashion in response to gamma-irradiation, and that nuclear expression of TPPII was present in most gamma-irradiated transformed cell lines.
Further, this required cellular production of ROS; treatment with either N-acetyl-Cysteine (anti-oxidant) or Rotenone (inhibitor of mitochondrial respiration) inhibited nuclear accumulation of TPPII.

The O (2)-induced contraction is mediated by the Rho kinase pathway, as fasudil and Y-27632 significantly relax the O (2) contracted DA.
As in the mammalian DA, inhibiting mitochondrion-derived reactive oxygen species production with rotenone and antimycin A relaxed the O (2)-constricted DA.

Increasing mitochondrial superoxide with inhibitors of electron transport (10 microM rotenone and antimycin) and by opening mitochondrial ATP-dependent K+ channels with 100 microM diazoxide were observed in this study to attenuate relaxation of BCA precontracted with 30 mM KCl to hypoxia by 68-76% and 38%, respectively.
