Cortex pseudolaricis, the root bark of Pseudolarix kaempferi Gord, has been used to treat tinea and other skin diseases for the antimicrobial activities in Traditional Chinese Medicine (TCM). Pseudolaric acid B (PAB) has been identified as the major component responsible for the action of C. pseudolaricis. Recently, PAB has been demonstrated to be used as novel treatments for cancer, immune disorders, inflammatory diseases, and immunosuppression. However, the mechanisms through which PAB exerts its properties are not understood well, and little attention in the literature has been given to review its pharmacological activities before...

BACKGROUND: Squamous cell carcinoma (SCC) is a common skin cancer that poses a risk of metastasis. Clinical investigations into SCC treatment are common, but the outcomes reported are highly variable, omitted, or clinically irrelevant. The outcome heterogeneity and reporting bias of these studies leave clinicians unable to accurately compare studies. Core outcome sets (COSs) are an agreed minimum set of outcomes recommended to be measured and reported in all clinical trials of a given condition or disease...

Secretion of granular glands from the skin of amphibians is a fascinating resource of active substances, particularly for cancer therapy in clinical practice of Traditional Chinese Medicine. A variety of anti-tumor peptides have been isolated from different toads and frogs; however, no anti-tumor peptides are reported in toad venom of Bufo gargarizans. Firstly, soluble fraction from fresh toad venom (FTV) was compared with that from dried toad venom (DTV), using HPLC analysis. It was revealed that FTV has a different HPLC chromatography compared with DTV...

Natural products or nutraceuticals have been shown to elicit anti-aging, anti-cancer and other health-enhancing effects. A key target of the effects of natural products may be the regulation of microRNA (miR) expression which results in cell death or prevents aging, diabetes, cardiovascular and other diseases. This review will focus on a few natural products, especially on resveratrol (RES), curcumin (CUR) and berberine (BBR). RES is obtained from the skins of grapes and other fruits and berries. RES may extend human lifespan by activating the sirtuins and SIRT1 molecules...

  Immune checkpoint inhibitors, used for cancer immunotherapy, show anti-tumor effects through T cell activations. Monoclonal antibodies against cytotoxic T lymphocyte antigen-4 (CTLA-4), programmed cell death (PD)-1, or PD-ligand 1 which is a ligand of PD-1 have been shown to be effective in the treatments of advanced cancers including malignant melanoma, non-small cell lung cancer, and renal cell carcinoma. However, these drugs also have immune-related adverse events (irAEs). The irAEs, which have unique characteristics different from those seen in conventional cytotoxic anti-tumor medicines, are observed in the several tissues such as skin, gastrointestinal tract, liver, lung, muscle, nerve and endocrine systems...

BACKGROUND: Immediate breast reconstruction in large and ptotic breasts is challenging, often requiring skin-reducing procedures. The Wise-pattern skin-reducing mastectomy (WPSRM) technique provides reliable one-stage implant coverage using the pectoralis muscle and a de-epithelialized inferiorly based dermal flap. However, de-vascularization may result in mastectomy skin flap necrosis. We aimed to critically evaluate and isolate patients at high risk of complications using this procedure...

Skin damage induced by UVR is an escalating problem in dermatology, and increasing incidence of skin cancer, especially for non-melanoma skin cancer, has been reported worldwide. UVR from sun exposure and the production of reactive oxygen species (ROS) is known to be a pivotal factor in the aetiology of skin cancer. The pineal hormone melatonin is recognized as the most potent endogenous antioxidant. Melatonin conducts its antioxidant effects acting directly as a radical scavenger and indirectly by up regulation of antioxidant enzymes...

BACKGROUND: Melanoma is a heterogeneous malignancy. We set out to identify the molecular underpinnings of high-risk melanomas, those that are likely to progress rapidly, metastasize, and result in poor outcomes. METHODS: We examined transcriptome changes from benign states to early-, intermediate-, and late-stage tumors using a set of 78 treatment-naive melanocytic tumors consisting of primary melanomas of the skin and benign melanocytic lesions. We utilized a next-generation sequencing platform that enabled a comprehensive analysis of protein-coding and -noncoding RNA transcripts...

Human pigmentation characteristics play an important role in the effects of sun exposure, skin cancer induction and disease outcomes. Several of the genes most important for this diversity are involved in the regulation and distribution of melanin pigmentation or enzymes involved in melanogenesis itself within the melanocyte cell present in the skin, hair and eyes. The single nucleotide polymorphisms and extended haplotypes within or surrounding these genes have been identified as risk factors for skin cancer, in particular, melanoma...
