Authors: Chen XY, Chen Y, Qu CJ, Pan ZH, Qin Y, Zhang X, Liu WJ, Li DF, Zheng Q Abstract Melanoma is the most malignant type of skin cancer and is resistant to numerous chemotherapeutic and radiotherapy-based treatment approaches due to the activation of rapid and reversible pro-survival signaling pathways. As a result, patients will often present with a poor prognosis. Therefore, novel preventive methods and treatments are urgently required for patients with melanoma. Vitamin C (also known as L-ascorbic acid) is a water-soluble vitamin that is widely used as a dietary additive and has been demonstrated to exhibit ...

Authors: Yang J, Pan Z, Zhou Q, Liu Q, Zhao F, Feng X, Lyu J Abstract The aim of the current study was to develop and validate a nomogram based on a large population to estimate the 3- and 5-year survival rates of patients with malignant melanoma (MM). Patients were selected from the Surveillance, Epidemiology and End Results database and randomly divided into the training and validation cohorts. A nomogram was developed, and was used to assess the accuracy of the model. Independent prognostic factors associated with overall survival (OS) rate were identified through multivariate analysis, and were included in the ...

Authors: Jia B, Zhao X, Wang Y, Wang J, Wang Y, Yang Y Abstract Breast cancer is the second leading cause of cancer-associated mortality among women worldwide, and the prevalence and mortality rates associated with this disease are high in Western countries. The melanoma-associated antigen (MAGE) family proteins are well-known tumor-specific antigens; this family includes>60 proteins that serve an important part in cell cycle withdrawal, neuronal differentiation and apoptosis. The aim of the present study was to identify a biomarker within the MAGE family that is specific for breast cancer. In the present study,...

We present a 48-year-old woman affected by metastatic uveal melanoma treated with nivolumab (3 mg/kg every 2 weeks). The patient had no previous history of autoimmune disease or dermatologic conditions. At the fourth month of treatment, on cutaneous examination, she presented multiple whitish vitiligo-like patches on the trunk, axillae, hands and face. Diagnosis of melanoma-associated leukoderma vitiliginous reaction was made. Over the following months, the melanoma-associated leukoderma lesions slowly progressed with cigarette paper-like appearance and indurated texture. A skin biopsy leaded the diagnosis of extragenital ...

Shen-OrrSummaryAlthough clonal neo-antigen burden is associated with improved response to immune therapy, the functional basis for this remains unclear. Here we study this question in a novel controlled mouse melanoma model that enab...

ConclusionsRural students reported less adequate use of sun protection than urban students. Rural male students reported lower knowledge scores compared to urban males. Future skin cancer prevention efforts targeting rural high schoolers are warranted.

Non-ablative pulsed focused ultrasound (pFUS) targets non-thermal forces that activate local molecular and cellular immune responses. Optimal parameters to stimulate immunotherapeutic tumor microenvironments (TME) and responses in different tumor types remain uninvestigated. Flank B16 murine melanoma and 4T1 breast tumors received 1 MHz pFUS at 1 –8 MPa peak negative pressures (PNP) and were analyzed 24 hr post-sonication. Necrosis or hemorrhage were unaltered in both tumors, but pFUS induced DNA strand breaks in tumor cells at PNP ≥6 MPa.

ConclusionsTo sum up, our outcomes exhibited that weakening GSTO1 reduced the proliferation and mobility of CMM cells, increased the apoptosis ability of CMM cells, and arrested cell cycle at G1 phase, which can be achieved by affecting the expression of PCNA, p53 and the EMT process. This discovery provided a new perspective for elucidating the mechanism of CMM, and offered theoretical support for searching clinical therapeutic targets in the future.
