“…In addition to the genetic defects associated with metastatic melanoma development there are several dysregulated key signaling pathways that occur during melanoma progression such as the WNT, MAPK, and PI3K/AKT pathways ( 22 , 34 , 35 ). These pathways are involved in melanoma cell proliferation, growth, survival, evading cell death, and acquiring metastatic properties ( 34 , 35 ). The MAPK and PI3K/AKT pathways can cooperate with each other in the transduction of survival signals ( 36 ).…”

“…Embryogenesis requires a single cell to proliferate and differentiate into various cell types and acquire migratory/invasive properties required for body patterning that parallels carcinogenesis ( 37 , 38 ). Signal transduction of the WNT, MAPK, and PI3K/AKT pathways in melanoma cells promotes altered expression of cell adhesion molecules and peptidases allowing for the remodeling of the extracellular matrix (ECM) to facilitate in cancer cell migration ( 34 , 39 – 42 ). During melanoma progression, elevated matrix metallopeptidase (MMP) expression and function have been detected ( 34 , 43 , 44 ).…”

Melanoma, a cancer of the skin, arises from transformed melanocytes. Melanoma has the highest mutational burden of any cancer partially attributed to UV induced DNA damage. Localized melanoma is “curable” by surgical resection and is followed by radiation therapy to eliminate any remaining cancer cells. Targeted therapies against components of the MAPK signaling cascade and immunotherapies which block immune checkpoints have shown remarkable clinical responses, however with the onset of resistance in most patients, and, disease relapse, these patients eventually become refractory to treatments. Although great advances have been made in our understanding of the metastatic process in cancers including melanoma, therapy failure suggests that much remains to be learned and understood about the multi-step process of tumor metastasis. In this review we provide an overview of melanocytic transformation into malignant melanoma and key molecular events that occur during this evolution. A better understanding of the complex processes entailing cancer cell dissemination will improve the mechanistic driven design of therapies that target specific steps involved in cancer metastasis to improve clinical response rates and overall survival in all cancer patients.

“…Changes in integrin expression have been studied extensively in melanoma carcinogenesis [8,25]. The integrin profile of melanoma cells differs significantly from that of normal melanocytes [26,27] and is closely related to the stage of melanoma progression [24,28].…”

“…Human cutaneous melanoma develops in a series of definable stages, from the common acquired nevus and dysplastic nevus through the radial growth phase (RGP) and vertical growth phase (VGP) of primary melanoma and finally metastatic melanoma. During these multistep transformations, melanoma cells acquire the ability to invade the dermis and then disseminate throughout the body via blood and lymphatic vessels [3][4][5][6][7][8]. Adjustment of integrin glycosylation is an important feature of the melanoma cell's adaptation to the constantly changing conditions of its microenvironment.…”

Each stage of melanoma development from transformed melanocytes to metastatic lesions requires the involvement of cell adhesion receptors, among which integrins are of particular importance. Strong N-glycosylation of αβ integrin heterodimers influences their processing, activation, and functions related to the modulation of cell adhesion to extracellular matrix proteins (ECM) and the basement membrane. A lack of N-glycans on integrin chains significantly reduces their interactions with the ECM. Melanoma progression is accompanied by changes in the composition of N-glycans on integrin subunits. The glycosylation profile of integrins depends on the stage of melanoma development and on the location of the metastasis. Enhanced expression of β1,6-branched complex-type oligosaccharides and altered sialylation are wellcharacterized changes in the N-glycosylation of integrins observed in melanoma progression. This chapter summarizes the current state of knowledge about α3β1, α5β1, and αvβ3 integrin glycosylation in melanoma and the functional consequences of changed glycosylation for the development of this cancer.
