Quantitative proteomics links the intermediate filament nestin to resistance to targeted BRAF inhibition in melanoma cells.

Mol Cell Proteomics 2019 Mar 19. Epub 2019 Mar 19.

Eberhard Karls University Tuebingen, Germany

Targeted inhibition of mutated kinases using selective MAP kinase inhibitors in malignant melanoma often results in temporary improvement of clinical symptoms followed by rapid development of resistance. To gain insights in molecular processes that govern resistance, we performed SILAC-based quantitative proteomics profiling of vemurafenib-resistant and -sensitive melanoma cells. Among down-regulated proteins in vemurafenib-resistant cell lines we detected multiple proteins involved in cytoskeletal organization and signaling, including the intermediate filament nestin, which was one of the most down-regulated proteins.

Adapalene suppressed the proliferation of melanoma cells by S-phase arrest and subsequent apoptosis via induction of DNA damage.

Eur J Pharmacol 2019 May 2;851:174-185. Epub 2019 Mar 2.

Hospital for Skin Disease, Institute of Dermatology, Chinese Academy of Medical Science, Peking Union Medical College, Nanjing 210042, PR China. Electronic address:

Malignant melanoma was the leading cause of mortality among the skin-associated cancer owing to its highly metastatic feature, increasing incidence and drug resistance requirement. Retinoids played important roles in the treatment of cancer via the activation of retinoid acid receptor (RAR) or retinoid X receptor (RXR). Our present study showed that the third-generation retinoid adapalene exhibited strong inhibitory effects on the proliferation of melanoma cells than other retinoids, such as all-trans-retinoic acid (ATRA), isotretinoin, acitretin and bexarotene, and adapalene exerted significant inhibitory effects on the colony formation of melanoma cells.

Stereotactic radiosurgery combined with immune checkpoint inhibitors or kinase inhibitors for patients with multiple brain metastases of malignant melanoma.

Melanoma Res 2019 04;29(2):187-195

Dermatology, University Medical Center Schleswig-Holstein, Kiel.

The aim was to evaluate toxicity and oncological outcome of combined stereotactic radiosurgery (SRS) and immunotherapy or targeted therapy in patients with multiple brain metastases originating from malignant melanoma. Despite the fact that both SRS and kinase inhibitors or immune checkpoint inhibitors are considered standard treatment options for this indication, the optimal combination and sequence of these modalities remains largely unknown, especially for patients with a high number of brain metastases. For this retrospective analysis, conducted in two large SRS dedicated centers, we identified patients with brain metastases from malignant melanoma and simultaneous application of immunotherapy or targeted therapy within 30 days of SRS.

Leukocyte⁻Cancer Cell Fusion-Genesis of a Deadly Journey.

Cells 2019 Feb 18;8(2). Epub 2019 Feb 18.

Department of Dermatology and The Yale Cancer Center, Yale School of Medicine, New Haven, CT 06520-8059, USA.

According to estimates from the International Agency for Research on Cancer, by the year 2030 there will be 22 million new cancer cases and 13 million deaths per year. The main cause of cancer mortality is not the primary tumor itself but metastasis to distant organs and tissues, yet the mechanisms of this process remain poorly understood. Leukocyte⁻cancer cell fusion and hybrid formation as an initiator of metastasis was proposed more than a century ago by the German pathologist Prof. Read More

Cancer Res 2019 Apr 18;79(8):2021-2030. Epub 2019 Feb 18.

Department of Biomedical Engineering, Wayne State University, Detroit, Michigan.

The current gold standard for clinical diagnosis of melanoma is excisional biopsy and histopathologic analysis. Approximately 15-30 benign lesions are biopsied to diagnose each melanoma. In addition, biopsies are invasive and result in pain, anxiety, scarring, and disfigurement of patients, which can add additional burden to the health care system. Read More

Pediatr Blood Cancer 2019 Jun 7;66(6):e27648. Epub 2019 Feb 7.

Department of Pediatrics, Hematology-Oncology Section, Texas Children's Cancer Center, Dan L. Duncan Comprehensive Cancer Center, Baylor College of Medicine, Houston, Texas.

Background: Epidemiological knowledge and predictors of melanoma among children and adolescents in multiethnic populations are limited.

Procedure: Using data from the Texas Cancer Registry (TCR) and the Surveillance, Epidemiology, and End Results (SEER) 13 database, we identified incident melanoma cases diagnosed at 0-20 years old during 1995-2013 in Texas and the United States, respectively. Using negative binomial regression, associations between demographic factors and melanoma incidence rates (IR) were evaluated by calculating incidence rate ratios (IRR) and 95% confidence intervals (CI).

Generation of an Oncolytic Herpes Simplex Virus 1 Expressing Human MelanA.

Front Immunol 2019 22;10. Epub 2019 Jan 22.

Institute of Medical Microbiology and Hygiene, University of Regensburg, Regensburg, Germany.

Robust anti-tumor immunity requires innate as well as adaptive immune responses. We have shown that plasmacytoid dendritic cells develop killer cell-like activity in melanoma cell cocultures after exposure to the infectious but replication-deficient herpes simplex virus 1 (HSV-1) 106S. To combine this innate effect with an enhanced adaptive immune response, the gene encoding human MelanA/MART-1 was inserted into HSV-1 106S via homologous recombination to increase direct expression of this tumor antigen.

Gene Expression and Methylation Analysis in Melanomas and Melanocytes From the Same Patient: Loss of NPM2 Expression Is a Potential Immunohistochemical Marker for Melanoma.

Front Oncol 2018 21;8:675. Epub 2019 Jan 21.

Division of Dermatology, Department of Internal Related, Kobe University Graduate School of Medicine, Chuo-ku, Japan.

DNA methylation is considered the primary epigenetic mechanism underlying the development of malignant melanoma. Since DNA methylation can be influenced by environmental factors, it is preferable to compare cancer and normal cells from the same patient. In order to compare the methylation status in melanoma tissues and melanocytes from the same individuals, we employed a novel epidermal sheet cultivation technique to isolate normal melanocytes from unaffected sites of melanoma patients.
