The NTCC? SK-MEL-23 cell line is a human melanoma cell line used extensively in cancer research. It was established from a metastatic lymph node of a 67-year-old female patient with malignant melanoma.

Key Characteristics

• Origin: The cell line was developed by Memorial Sloan Kettering Cancer Center (MSKCC). It's one of a large series of melanoma cell lines derived by researchers to study the disease.

• Melanin Production: SK-MEL-23 cells are notable for being highly pigmented, meaning they contain a significant amount of melanin. This feature makes them a valuable model for studying the effects of melanin and melanogenesis (the process of melanin synthesis) on various treatments and cellular processes.

• Genetic Profile: The cell line has a homozygous deletion in the PTEN gene. This is a significant characteristic, as PTEN is a well-known tumor suppressor gene. The loss of PTEN function is common in many cancers, including melanoma, and leads to the activation of pro-survival pathways.

• Morphology and Growth: SK-MEL-23 cells are adherent and grow as a monolayer.

Research Applications

Due to its specific characteristics, the SK-MEL-23 cell line is a critical tool for several areas of research:

• Melanoma Biology: It serves as a model for understanding the biology of malignant melanoma, particularly the role of melanin in the disease's progression and response to therapy.

• Drug and Therapy Screening: The cell line is used to test the efficacy of new drugs and therapies, including targeted agents and immunotherapies. Its response to a wide range of compounds is well-documented, making it a reliable model for preclinical studies.

• Photobiology and Laser Research: Its high melanin content makes it an ideal model for studying the effects of light, particularly lasers, on pigmented cells. Researchers have used it to investigate sub-lethal damage from laser exposure and its effect on melanin content and related genes like tyrosinase.

NTCC? SK-MEL-23 細(xì)胞系是一種廣泛用于癌癥研究的人類黑色素瘤細(xì)胞系。它建立于一名67歲女性惡性黑色素瘤患者的轉(zhuǎn)移性淋巴結(jié)。

主要特點(diǎn)

• 來(lái)源: 該細(xì)胞系由紀(jì)念斯隆-凱特琳癌癥中心（MSKCC）開發(fā)。它是一系列為研究該疾病而分離的黑色素瘤細(xì)胞系中的一個(gè)。

• 黑色素生成: SK-MEL-23 細(xì)胞的一個(gè)顯著特點(diǎn)是其高度色素化，意味著它們含有大量的黑色素。這一特性使其成為研究黑色素及其合成過(guò)程（黑素生成）對(duì)各種治療和細(xì)胞過(guò)程影響的寶貴模型。

• 遺傳學(xué)特征: 該細(xì)胞系在 PTEN 基因中存在純合性缺失。這是一個(gè)重要特征，因?yàn)?PTEN 是一個(gè)著名的抑癌基因。PTEN 功能的喪失在包括黑色素瘤在內(nèi)的許多癌癥中很常見，并導(dǎo)致促生存通路的激活。

• 形態(tài)與生長(zhǎng): SK-MEL-23 細(xì)胞是貼壁生長(zhǎng)的，形成單層。

研究應(yīng)用

由于其獨(dú)特的特性，SK-MEL-23 細(xì)胞系是幾個(gè)研究領(lǐng)域的關(guān)鍵工具：

• 黑色素瘤生物學(xué): 它作為研究惡性黑色素瘤生物學(xué)的模型，特別是研究黑色素在該疾病進(jìn)展和治療反應(yīng)中的作用。

• 藥物和療法篩選: 該細(xì)胞系用于測(cè)試新藥物和療法（包括靶向藥物和免疫療法）的有效性。它對(duì)各種化合物的反應(yīng)有詳細(xì)記錄，使其成為臨床前研究的可靠模型。

• 光生物學(xué)和激光研究: 其高黑色素含量使其成為研究光（特別是激光）對(duì)色素細(xì)胞影響的理想模型。研究人員已用它來(lái)研究激光照射造成的亞致死性損傷及其對(duì)黑色素含量和相關(guān)基因（如酪氨酸酶）的影響。
