Malignant melanoma is one of the most leading form of skin cancer associated with a low patient survival rate. Increasing evidence revealed that microRNAs (miRNAs) play a crucial role in the occurrence and development of several form of cancer including melanoma. In this study, we aimed at investigating the expression and role of miR-143-3p in human malignant melanoma. Our results showed that the expression of miR-143-3p was lower in human melanoma cells, as well as human biopsy specimens, when compared to normal human melanocytes. Ectopic expression of miR-143-3p in human melanoma cells inhibited proliferation, migration, invasion and promoted apoptosis acting through a molecular mechanism that, at least in part, is dependent on inhibition of cyclooxygenase-2 (COX-2) gene. Collectively, these results demonstrate that miR-143-3p could represent at the same time, a new early diagnostic marker and therapeutic target acting as tumor suppressor in melanoma cancer.

Melanoma is one of the most aggressive malignant tumors, with increasing incidence, poor prognosis, and lack of any effective targeted therapies. Abnormal expression of miR-29a has been found in sever...
Appropriate post-translational processing of collagen requires prolyl hydroxylation, catalyzed by the prolyl 3- (C-P3H) and prolyl 4- (C-P4H) hydroxylases is essential for normal cell function. Here w...
Hexokinase-2 (HK2), the initial as well as the rate-limiting step in glycolysis, is overexpressed in many human cancers, and correlates with poor clinical outcomes. Aerobic glycolysis is a hallmark of...
Tumor-derived exosomes (TEX) play an important role in the escape of tumor cells from immune surveillance. However, the details of the mechanism are not fully understood. In this study, the apoptosis ...
The fucose salvage pathway is a two-step process in which mammalian cells transform L-fucose into GDP-L-fucose, a universal fucose donor used by fucosyltransferases to modify glycans. Emerging evidenc...
This study is designed to investigate the biomarkers, pharmacodynamics and pharmacokinetics of the liposomal micro-ribonucleic acid-34 (microRNA-34, miR-34). Melanoma patients with easily ...
Considerable progress in the treatment of metastatic melanoma has been made in the past 5years, with the approval of immune checkpoint-blocking antibodies and agents targeting BRAF mutatio...
This phase Ib/II trial studies how well dendritic cell therapy after cryosurgery in combination with pembrolizumab works in treating patients with stage III-IV melanoma that cannot be remo...
The purpose of this clinical trial is to assess the activity of thalidomide in combination with dacarbazine (DTIC) in patients with metastatic melanoma. Safety and toxicity of the two dru...
This randomized phase III trial studies how well initial treatment with ipilimumab and nivolumab followed by dabrafenib and trametinib works and compares it to initial treatment with dabra...
An unpigmented malignant melanoma. It is an anaplastic melanoma consisting of cells derived from melanoblasts but not forming melanin. (Dorland, 27th ed; Stedman, 25th ed)
A non-steroidal anti-inflammatory agent (NSAID) that inhibits the enzyme cyclooxygenase necessary for the formation of prostaglandins and other autacoids. It also inhibits the motility of polymorphonuclear leukocytes.
A Wnt protein and ligand for FRIZZLED RECEPTORS that may function as an inhibitor or activator of the WNT SIGNALING PATHWAY. For example, it activates signaling in the presence of Frizzled-4 but is inhibitory when coupled with ROR2 TYROSINE KINASE. It is required for axis formation during EMBRYOGENESIS and inhibits the proliferation, migration, and invasiveness of cancer cells.
Found in large amounts in the plasma and urine of patients with malignant melanoma. It is therefore used in the diagnosis of melanoma and for the detection of postoperative metastases. Cysteinyldopa is believed to be formed by the rapid enzymatic hydrolysis of 5-S-glutathionedopa found in melanin-producing cells.
A melanosome-specific protein that plays a role in the expression, stability, trafficking, and processing of GP100 MELANOMA ANTIGEN, which is critical to the formation of Stage II MELANOSOMES. The protein is used as an antigen marker for MELANOMA cells.
A microRNA (abbreviated miRNA) is a small non-coding RNA molecule (containing about 22 nucleotides) found in plants, animals, and some viruses. Key findings: miRNA is involved in the normal functioning of eukaryotic cells, so has dysregulation...
Melanoma is a highly malignant tumor of melanin-forming cells (melanocytes) There are most commonly found in the skin (resulting from sunlight exposure), but also in the eyes and mucous membranes. Metastasis to other regions of the body is also common....
There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma and malignant melanoma. Basal cell carcinoma Basal cell carcinoma, or BCC, is a cancer of the basal cells at the bottom of the epidermis. It’s very common ...
