BioVector® LPS141 人去分化脂肪肉瘤细胞系 / LPS141 Human Dedifferentiated Liposarcoma Cell Line
一、 背景与来源说明 / Background & Origin
【中文】BioVector® LPS141 是一种源自人去分化脂肪肉瘤(Dedifferentiated Liposarcoma, DDLPS)的稳定肿瘤细胞系。去分化脂肪肉瘤属于高度恶性的软组织肉瘤,其基因组显著特征是 12q13-15 区段的高度扩增,导致 MDM2 和 CDK4 原癌基因的大量过表达。
【English】BioVector® LPS141 is a human tumor cell line derived from Dedifferentiated Liposarcoma (DDLPS). Dedifferentiated liposarcoma is a highly aggressive subtype of soft tissue sarcoma characterized by high-level amplification of the 12q13-15 chromosomal region, leading to marked overexpression of the MDM2 and CDK4 oncogenes.

【中文】 LPS141 细胞系完整保留了原始肿瘤的分子遗传学特征(MDM2/CDK4 双扩增),且由于 MDM2 过表达强烈抑制 p53 功能,该细胞系成为研究 MDM2-p53 相互作用阻断剂、CDK4/6 抑制剂(如 Palbociclib)以及联合靶向治疗方案的经典体外和异种移植(Xenograft)模型。
【English】 The LPS141 cell line faithfully retains the key molecular alterations of the primary tumor (MDM2/CDK4 co-amplification). Because MDM2 overexpression suppresses p53 function, LPS141 serves as an established in vitro and xenograft model for evaluating MDM2-p53 antagonists, CDK4/6 inhibitors (e.g., Palbociclib), and combination targeted therapies.
