Melanoma is a malignant tumor of melanocytes that is a serious threat to human health. Dermatan sulfate (DS) is a natural glycosaminoglycan. Inspired by the origin of DS, we report a DS-functionalized biomimetic chitosan nanocarrier (DCNP) for melanoma targeted chemotherapy. DS can anchor to the surface of the chitosan nanocarrier (CNP) by forming amide bond. The SN38/DCNP can rapidly release the anti-tumor drug under acidic conditions. The functionalization of DS not only promoted the specific uptake behavior of melanoma cells, but also up-regulated cleaved caspase-3 and PARP promote tumor cell apoptosis. In vivo model, DCNP reduced the non-specific distribution of SN38 in the circulation and other tissues, while shows superior tumor targeting ability. SN38/DCNP significantly inhibit tumor growth and improved the survival rate. Moreover, SN38/DCNP has a milder myelosuppressive effect. The above results indicated that DS could be used as an excellent targeting unit for the treatment of melanoma.

Purpose: Precision medicine plays an important role in the treatment of patients with advanced melanoma. Despite its high incidence in White patients, advanced melanoma is rare in Asian countries, hampering prospective clinical trials targeting the Asian population. This retrospective study aimed to elucidate the real-world molecular diagnoses and outcomes of Japanese patients with melanoma using comprehensive genome profiling (CGP).

This study identifies microRNAs (miRNAs) with significant discriminatory power in distinguishing melanoma from nevus, notably hsa-miR-26a and hsa-miR-211, which have exhibited diagnostic potential with accuracy of 81% and 78% respectively. To enhance diagnostic accuracy, we integrated miRNAs into various machine-learning (ML) models. Incorporating miRNAs with AUC scores above 0.

Purpose: Histone deacetylase 6 (HDAC6) plays a critical role in tumorigenesis and tumor progression, contributing to proliferation, chemoresistance, and cell motility by regulating microtubule architecture. Despite its upregulation in melanoma tissues and cell lines, the specific biological roles of HDAC6 in melanoma are not well understood. This study aims to explore the functional effects and underlying mechanisms of WT161, a selective HDAC6 inhibitor, in melanoma cell lines.

The incidence of melanoma has increased for decades, and while surgical treatment of early stage disease is often curative, metastatic disease continues to have significant morbidity and mortality and carries a high associated health burden and economic cost. An expanding number of dermatologists are playing a key role in coordinating the care of patients with advanced melanoma, including in the setting of multidisciplinary melanoma clinics, many of which are anchored in dermatology departments. Advances in the understanding of the genetic and immunoregulatory aspects of melanoma development and progression have yielded a wave of novel therapeutics that has made significant impact on the approach to patients with metastatic disease.
