Phytochemical study of Sinningia reitzii (Gesneriaceae) led to the isolation of three new naphtoquinones, 6,7-dimethoxydunnione, 7-hydroxy-6-methoxydunnione, and 5-hydroxy-6,7-dimethoxydunnione from the tubers, together with four known compounds, 7-hydroxydunnione, 8-hydroxydunnione, 5-hydroxy-6,7-dimethoxy- α -dunnione, and 8-hydroxydeydrodunnione. Aerial parts furnished five known compounds, 5-hydroxy-6,7-dimethoxydunniol, 6,8-dihydroxy-7-methoxy-2-O-methyldunniol, loureirin B, jacaranone, and methyl 4-hydroxyphenylacetate. Compounds 8-hydroxydunnione, 5-hydroxy-6,7-dimethoxy- α -dunnione, 8-hydroxydeydrodunn...

Melanoma immunotherapy, specifically the autotransplant of dendritic cells charged with tumors antigens, has shown promising results in clinical trials. The positive clinical effects of this therapy have been associated to increased Th17 response and delayed-type hypersensitivity (DTH) against to tumor antigens. Some synthetic compounds, such as diphenylcyclopropenone (DPCP), are capable of triggering a DTH response in cutaneous malignancies and also to induce clinically relevant effects against melanoma. In this work, we evaluated Litre extract (LExT), a standardized extract of a Chilean stinging plant, Lithraea caustic (...

Expression patterns of estrogen receptors [ERα, ERβ, and G-protein associated ER (GPER)] in melanoma and skin may suggest their differential roles in carcinogenesis. Phytoestrogenic compound cyanidin-3-o-glucoside (C3G) has been shown to inhibit the growth and metastatic potential of melanoma, although the underlying molecular mechanism remains unclear. The aim of this study was to clarify the mechanism of action of C3G in melanoma in vitro and in vivo, as well as to characterize the functional expressions of ERs in melanoma. In normal skin or melanoma (n = 20/each), no ERα protein was detectable, whereas ...

Adoptive T cell therapy using patient T cells redirected to recognize tumor-specific antigens by expressing genetically engineered high-affinity T-cell receptors (TCRs) has therapeutic potential for melanoma and other solid tumors. Clinical trials implementing genetically modified TCRs in melanoma patients have raised concerns regarding off-target toxicities resulting in lethal destruction of healthy tissue, highlighting the urgency of assessing which off-target peptides can be recognized by a TCR. As a model system we used the clinically efficacious NY-ESO-1-specific TCR C259, which recognizes the peptide epitope SLLMWITQ...

Authors: Wang B, Tian Y, Yin Q Abstract AIM2 (absent in melanoma 2) is a cytoplasmic sensor of double-stranded DNA from pathogens or damaged cellular organelles. It recruits ASC (apoptosis-associated specklike protein containing a CARD) and caspase-1 to form the AIM2 inflammasome, activate caspase-1, and elicit inflammatory responses via cytokine maturation and pyroptotic cell death. Structural studies from X-ray crystallography, NMR, and cryo-EM have revealed many details in AIM2 inflammasome activation, assembly, and regulation. Many principles learned from AIM2 inflammasome also apply to other inflammasomes. In ...

In this report, we analyzed gene expression profiles of paired specimens of keratinocyte carcinomas with their matched normal skin tissues as the control. Among several novel findings, we discovered a significant number of zinc finger encoding genes up-regulated in human BCC. In BCC, a novel link was found between hedgehog signaling, Wnt signaling, and the cilium. While the SCC cancer-stem-cell gene signature is shared between human and mouse SCCs, the hair follicle stem-cell signature of mice was not highly represented in human SCC. Differential gene expression (DEG) in human BCC shares gene signature with both bulge and ...

Conclusion We present a complete overview of artificial intelligence implemented in dermatology. Impressive outcomes were reported in all of the identified eight categories, but head-to-head comparison proved difficult. The many areas of dermatology where we identified machine learning tools indicate the diversity of machine learning. PMID: 31625775 [PubMed - as supplied by publisher]

Authors: Philipp-Dormston WG, Battistella M, Boussemart L, Di Stefani A, Broganelli P, Thoms KM Abstract Introduction: Actinic keratosis (AK) is a chronic skin condition that can be a precursor to cutaneous squamous cell carcinoma. AK can recur and patients are likely to undergo multiple treatments. It is important that AK lesions are managed appropriately, and that patients are involved in treatment decisions. Materials and methods: The Supporting Professional Expertise in AK (SPEAK) program aims to facilitate this patient-centered care by identifying patient needs and aiding healthcare practitioners (HCPs) in sel...
