Foci of inflammasome activation were co-localised with these immune cell infiltrate, with significantly increased staining for adaptor protein ASC (apoptosis-associated speck-like protein containing a caspase activation and recruitment domain) and active caspase-1 in the RIAKI tissue compared to the healthy control. Our clinical findings identify multiple pathophysiological pathways previously only reported in murine RIAKI, providing first evidence in humans linking deposition of myoglobin and presence of uric acid to tubular oxidative stress/necroptosis, inflammasome activation and necroinflammation.Colorectal cancer (CRC) is the second cause of cancer death worldwide. The metastatic disease is mainly treated with aggressive therapies consisting on combinations of cytotoxic chemotherapy plus anti-EGFR or anti-VEGF drugs. In spite of the improvements in clinical outcomes achieved in the last decade, these are the result of multiple new combinations using the existing therapeutic options and the introduction of regorafenib and TAS-102 in second or later lines of treatment. As immunotherapies are limited to less than 5% of CRC patients harboring tumors with deficient mismatch repair, there is an urgent need of finding new drugs to increase our patients' survival opportunities. Among all the natural products that are candidates to be used for the treatment of CRC cancer, curcumin (the golden spice) is in the spotlight. Used for centuries in the Ayurveda medicine, its demonstrated anticancer properties and low toxicity profile made it the focus of hundreds of preclinical and clinical investigations. So far we know that it can be combined with most of the aforementioned drugs in a safe and synergistic way. Regretfully, its poor bioavailability has been one of the main issues for its successful introduction in the clinic. Nevertheless, a plethora of new formulations with a huge increase in bioavailability are under study with promising results. In this review we discuss the possibility of incorporating curcumin in the treatment of CRC; specifically, we review preclinical and clinical data supporting its possible combination with current therapies as well as new formulations under clinical study. It is time for the golden spice revolution.Macular images of infants with early-onset edema (occurring at or before 33 weeks' postmenstrual age [PMA]) and infants with late-onset edema (at or after 36 weeks' PMA) were compared. At first appearance, early-onset edema has a more severe morphology, with foveal bulging and elongated cystoid spaces than late-onset edema, which presents as small cystoid spaces outside the foveal center. Morphological variations may be an indicator of the underlying cause of edema in preterm infants. The presence of mostly parafoveal small cystoid spaces in the late-onset edema group may be suggestive of an association with neurological injury.Gastrointestinal (GI) cancers with a high incidence rate and adverse complications are related to severe morbidity and mortality around the world. MicroRNAs (miRs) are potential regulators of cellular events, and their aberrant expression occurs in gastrointestinal (GI) cancers. Increasing evidence demonstrates that plant derived-natural compounds are capable of regulation of miRs in cancer therapy. Curcumin is a naturally occurring nutraceutical compound isolated from curcuma longa and possesses valuable pharmacological activities in which anti-tumor activity is of importance, since in suppressing cancer malignancy, curcumin can target various molecular pathways such as STAT3, PTEN, PI3K/Akt, Wnt, and so on. In the present review, our aim is to shed some light on regulation of miRs by curcumin in GI cancers, and demonstrate how regulation of miRs by curcumin can affect proliferation and metastasis of GI cancers. Noteworthy, curcumin affects down-stream targets such as PTEN, VEGFA, PI3K/Akt and so on that are responsible for growth and migration of GI cancers via regulation of miRs. Affected miRs, and their down-stream targets are discussed in this review in a mechanistic way. Besides, challenges for clinical translation of current studies are described.Astragaloside IV (ASIV) is the essential active component of astragalus that has diverse biological activities. Previous research has suggested its potentially beneficial effects on diabetic nephropathies. However, its effects and protective mechanism remain unclear. In this study, we conducted a preclinical systematic review to evaluate the efficacy and potential mechanisms of ASIV in reducing kidney damage in diabetes mellitus (DM) models. Studies were searched from nine databases until January 2020. A random-effects model was used to calculate combined standardised mean difference estimates and 95 % confidence intervals. Risk of bias of studies was assessed using the Systematic Review Center for Laboratory Animal Experimentation risk of bias tool 10-item checklist. RevMan 5.3 software was used for statistical analysis. Endoxifen clinical trial Twenty-three studies involving 562 animals were included in the meta-analysis. Studies quality scores ranged from 2 to 5. The ASIV group induced a marked decrease in serum creatinine (P less then 0.00001), blood urea nitrogen (P less then 0.00001), 24-h urine protein (P less then 0.00001) and pathological score (P less then 0.001) compared with the control group. The determined potential mechanisms of ASIV action were relieving oxidative stress, delaying renal fibrosis, anti-apoptosis and anti-inflammatory action. We conclude that ASIV exerts renal protective effects in animals with DM through multiple signalling pathways.
The pathogenesis of cardiomyopathy in metabolically unhealthy obesity (MUO) has been well studied. However, the pathogenesis of cardiomyopathy typically associated with high cholesterol levels in metabolically unhealthy nonobesity (MUNO) remains unclear. We investigated whether cholesterol-generated LysoPCs contribute to cardiomyopathy and the role of cytosolic phospholipase A2 (cPLA2) inhibitor in cholesterol-induced MUNO.
Cholesterol diet was performed in Sprague-Dawley rats that were fed either regular chow (C), or high cholesterol chow (HC), or HC diet with 10 % fructose in drinking water (HCF) for 12 weeks. LysoPCs levels were subsequently measured in rats and in MUNO human patients. The effects of cholesterol-mediated LysoPCs on cardiac injury, and the action of cPLA2 inhibitor, AACOCF3, were further assessed in H9C2 cardiomyocytes.
HC and HCF rats fed cholesterol diets demonstrated a MUNO-phenotype and cholesterol-induced dilated cardiomyopathy (DCM). Upregulated levels of LysoPCs were found in rat myocardium and the plasma in MUNO human patients.
