Pulmonary fibrosis, a potentially fatal disease, results from acute and chronic interstitial lung diseases. Fucoxanthin (Fx), a carotenoid found in brown seaweed, shows a wide range of pharmacological activities. In this study, we investigated the antifibrotic effects of fucoxanthin and their underlying molecular mechanisms in transforming growth factor-beta1 (TGF-β1)-stimulated human pulmonary fibroblasts (HPFs). Thus, the effects of Fx on TGF-β1-induced expression of fibrotic factors, such as alpha-smooth muscle actin (α-SMA), type 1 collagen, fibronectin, and interleukin-6 (IL-6), in HPFs were investigated...

Diabetic nephropathy (DN), a common complication associated with both type I and type II diabetes mellitus (DM), is a major cause of chronic nephropathy and a common cause of end-stage renal diseases (ESRD) throughout the world. This study is aimed to determine whether dencichine (De) can ameliorate renal damage in high-glucose-and-fat diet combined STZ (streptozocin) induced DN in type II DM rats and to investigate the potential underlying mechanisms. Markers of metabolism, diabetes, and renal function, and levels of extracellular matrix (ECM) collagen I (Col I), collagen IV (Col IV), fibronectin (FN) and laminin (LN), and of proteins in the TGF-β/Smad pathway were analysed through RT-PCR, western blot, immunofluorescence and immunohistochemistry...

Neuropathic pain affects millions of people causing disability and impairing quality of life. Commonly used analgesics are generally characterized by limited therapeutic outcomes. The serotonin 5-HT1A receptor and the α2 adrenergic receptors are involved in central nociceptive mechanisms with a pivotal role in the inhibitory descending pain pathway. Since their stimulation may modulate the nervous signaling altered by neuropathies, the purpose of the present research is the study of the combined activation of 5-HT1A and α2 receptors by rationally designed imidazoline ligands ((S)-1 and 2-5) in a rat model of neuropathic pain (chronic constriction injury - CCI)...

Alzheimer's disease (AD) is emerging as the most prevalent and socially disruptive illness of aging populations as more people live long enough to become affected. Although AD is placing a considerable and increasing burden on patients, caregivers and society, it represents the largest unmet medical need in neurology, because it is currently incurable. In the last few years, the amyloid hypothesis, which points to amyloid β-peptide (Aβ) as the initiating factor in AD, had a central role in the development of therapeutic strategies for AD...

Human podocytes (hPC) are essential for maintaining normal kidney function and dysfunction or loss of hPC play a pivotal role in the manifestation and progression of chronic kidney diseases including diabetic nephropathy. Previously, α-Lipoic acid (α-LA), a licensed drug for treatment of diabetic neuropathy, was shown to exhibit protective effects on diabetic nephropathy in vivo. However, the effect of α-LA on hPC under non-diabetic conditions is unknown. Therefore, we analyzed the impact of α-LA on cell viability and expression of nephrin and zinc finger protein 580 (ZNF580) in normal hPC in vitro...

Idiopathic pulmonary arterial hypertension (IPAH) is a fatal disease of the pulmonary artery resulting from a currently unidentified etiology. IPAH is pathologically characterized as sustained vasoconstriction and vascular remodeling of the pulmonary artery. Vascular remodeling is mediated by enhanced proliferation and reduced apoptosis in pulmonary arterial smooth muscle cells (PASMCs). Based on its pathological mechanism, specific phosphodiesterase type 5 (PDE5) inhibitors have been used in the treatment of IPAH...
