Multipotent stromal cells (MSCs) are currently in clinical trials for a number of inflammatory diseases. Recent studies have demonstrated the ability of MSCs to attenuate inflammation in rodent models of acute lung injury (ALI) suggesting that MSCs may also be beneficial in treating ALI. To better understand how human MSCs (hMSCs) may act in ALI, the lungs(More)
Marinobufagenin (MBG) is an endogenous mammalian cardiotonic steroid that is involved in the inhibition of the sodium pump Na(+)/K(+)-ATPase. Increased plasma levels of MBG have been reported in patients with volume expansion-mediated hypertension and preeclampsia. We have recently demonstrated that MBG impairs both the proliferation and growth(More)
Currently, patients with end-stage lung disease are limited to lung transplantation as their only treatment option. Unfortunately, the lungs available for transplantation are few. Moreover, transplant recipients require life-long immune suppression to tolerate the transplanted lung. A promising alternative therapeutic strategy is decellularization of whole(More)
Adipose-derived stem cells (ASCs) have emerged as important regulators of inflammatory/immune responses in vitro and in vivo and represent attractive candidates for cell-based therapies for diseases that involve excessive inflammation. Acute lung injury (ALI) is an inflammatory condition for which treatment is mainly supportive due to lack of effective(More)
Adipose-derived stromal/stem cells (ASCs) have anti-inflammatory as well as immunosuppressive activities and are currently the focus of clinical trials for a number of inflammatory diseases. Acute lung injury (ALI) is an inflammatory condition of the lung for which standard treatment is mainly supportive due to lack of effective therapies. Our recent(More)
BACKGROUND Preeclampsia is a human pregnancy-associated syndrome associated with hypertension, proteinuria, and endothelial dysfunction. We tested whether increased reactive oxygen species (superoxide and peroxynitrite) production and decreased bioavailability of the endothelial nitric oxide (NO) synthase (eNOS) cofactor tetrahydrobiopterin (BH4)(More)
Preeclampsia is a disorder that continues to exact a significant toll with respect to maternal morbidity and mortality as well as fetal wastage. Furthermore, the treatment of this disorder has not changed significantly in 50 years and is unsatisfactory. The use of diuretics in this syndrome is controversial because there is a concern related to potential(More)
The activity of mammalian pyruvate dehydrogenase complex (PDC) is regulated by a phosphorylation/dephosphorylation cycle. Dephosphorylation accompanied by activation is carried out by two genetically different isozymes of pyruvate dehydrogenase phosphatase, PDP1c and PDP2c. Here, we report data showing that PDP1c and PDP2c display marked biochemical(More)
BACKGROUND/AIMS There are two major pathophysiologic processes involved in the development of hypertension: (1) expanded extracellular fluid volume and (2) vasoconstriction. We have developed a model of preeclampsia in the rat, in which excessive volume expansion (VE) plays a role. These animals excrete increased amounts of the bufodienolide,(More)
BACKGROUND Endothelial barrier dysfunction (EBD) involves microtubule disassembly and enhanced cell contractility. Histone deacetylase 6 (HDAC6) deacetylates α-tubulin, and thereby destabilizes microtubules. This study investigates a role for HDAC6 in EBD. METHODS EBD was induced with thrombin±HDAC6 inhibitors (tubacin and MC1575), and assessed by(More)
