BACKGROUND: Candida tropicalis was one of the most common non-albicans Candida (NACA) species creating relatively high morbidity and mortality. We previously demonstrated that the antifungal effect of BBR in combination with FLC might be attributed to reactive oxygen species production, ergosterol content and efflux pump levels in a clinical C. tropicalis isolate. METHODS: we employed thirteen clinical C. tropicalis isolates as well as four standard reference strains to evaluate the antifungal activity of BBR in combination with FLC under planktonic and biofilm states by analyzing the mRNA expressions of ERG11, CDR1 and MDR1 by qRT-PCR...

Berberine (BBR) is an isoquinoline alkaloid found in different plant families such as Berberidaceae, Ranunculaceae, and Papaveraceae. BBR is well-known for its anti-inflammatory, lipid-modifying, anticancer, anti-diabetic, antibacterial, antiparasitic and fungicide activities. Multiple pharmacological actions of BBR stem from different molecular targets of this phytochemical. MicroRNAs (miRs) are single-stranded, evolutionary conserved, small non-coding RNA molecules with a length of 19-23 nucleotides that are involved in RNA silencing and post-transcriptional regulation of gene expression through binding to the 3'-untranslated region (3'UTR) of target mRNA...

Parkinson's disease (PD) is a neurodegenerative disorder bearing motor and nonmotor symptoms. The treatment today is symptomatical rather than preventive or curative and this leaves the field open for the search of both novel molecular targets and drug candidates. Interference with α-synuclein fibrillation, monoamine oxidase (MAO) inhibition, modulation of adenosine receptors and the inhibition of specific phosphodiesterase (PDE) isoforms are some of the currently pursued strategies. We synthesised and studied some semi-synthetic berberine derivatives using a set of in silico tools...

The activation of oncogenes can reprogram tumor cell metabolism. Here, in diffuse large B-cell lymphoma (DLBCL), serum metabolomic analysis revealed that oncogenic MYC could induce aberrant choline metabolism by transcriptionally activating the key enzyme phosphate cytidylyltransferase 1 choline-α (PCYT1A). In B-lymphoma cells, as a consequence of PCYT1A upregulation, MYC impeded lymphoma cells undergo a mitophagy-dependent necroptosis. In DLBCL patients, overexpression of PCYT1A was in parallel with an increase in tumor MYC, as well as a decrease in serum choline metabolite phosphatidylcholine levels and an International Prognostic Index, indicating intermediate-high or high risk...

Berberine, a quaternary isoquinoline alkaloid present in Berberis aristata, is well known in terms of cholesterol-lowering, hypoglycemic, and insulin sensitizing effects. Because of its low oral bioavailability, to improve intestinal absorption it has been recently combined with silymarin (Silybum marianum). The aim of our placebo controlled study was to evaluate the effects of its association with silymarin on abdominal fat in overweight/obese patients with type 2 diabetes mellitus (T2DM). To do so, 136 obese subjects with T2DM and metabolic syndrome were analyzed for fasting blood glucose and insulin, Insulin Resistance index according to the Homeostatic Model Assessment (HOMA-R), total, HDL and LDL cholesterol, triglycerides, uric acid, BMI, waist circumference, waist to hip ratio and underwent bioelectrical impedance to assess % of abdominal fat...

IL-8 over-expression could enhance cancer metastasis. In present study, berberine hydrochloride (BER) triggered proliferative inhibition and G2/M arrest in AGS cells, down-regulated protein expression of cyclin B1, Bcl-2, up-regulated expression of p21, p53 and cleaved caspase 3, but showed no effect on protein expression of CHOP, Bip, and caspase 4. BER could down-regulate the enhanced IL-8 expression through down-regulating ERK1/2 and p38 MAPK over-activation induced by SN 38. The increased IL-8 mediated adhesive ability of AGS cells to HUVECs induced by SN 38, could be reduced by BER...
