腺瘤息肉病大肠杆菌(APC)基因是一种肿瘤抑制基因,其编码的蛋白在 Wnt/β-catenin 信号通路 中起到关键的调控作用 [1]。 APC 蛋白能够拮抗 Wnt 信号通路,协助调控细胞迁移、黏附、转录激活和凋亡。 超过 10%的人类肿瘤存在 APC 基因的变异,其中绝大多数结直肠癌中都存在 APC 基因的突变 [2]。 APC 基因缺陷会导致以直肠部位多发成百上千个腺瘤性息肉为特征的家族性腺瘤性息肉病(FAP)的发生,这是一种常染色体显性恶性肿瘤前疾病,通常会发展为恶性肿瘤 [1 …
Mouse model of colorectal and intestinal cancer - Wikipedia
Mouse models of colorectal cancer and intestinal cancer are experimental systems in which mice are genetically manipulated, fed a modified diet, or challenged with chemicals to develop malignancies in the gastrointestinal tract.
APCMin/+小鼠自发性结直肠癌癌前病变模型-
APC(adenomatosis polyposis coli)基因编码的蛋白是一种肿瘤抑制蛋白,充当Wnt信号传导途径的拮抗剂。 APC-β-catenin-TCF主导的Wnt通路失调是家族腺瘤息肉病发生的主要途径。 APC蛋白表达的缺失或降低可能导致β-catenin免于降解,使游离的β-catenin在胞浆内集聚并进入核内,激活相关靶癌基因,导致细胞癌变的发生。 APC蛋白还涉及其他生物调节过程,包括细胞迁移和粘附,转录激活和细胞凋亡。 APC-Min(Min: multiple intestinal neoplasia)突变小鼠特指APC基 …

Acarbose improved survival for Apc+/Min mice
2020年2月20日 · Apc+/Min is a mouse model prone to intestinal polyposis and a mimic of familial adenomatous polyposis in people. Polyp-associated anemia contributed to their death. To address this knowledge gap, we fed two doses of acarbose to Apc+/Min mice.
APC的作用及在结直肠癌中的治疗潜能 - MedSci.cn
腺瘤性结肠息肉(APC)病基因是结直肠癌抑癌基因,可在胚系和体系水平出现异常调节。 APC位于5q21-q22,含8535核酸,21外显子,编码310 kDa蛋白,含2843氨基酸,75%编码序列位于外显子15,是胚系和体突变最常发生部位。 胚系突变致家族性腺瘤息肉病(FAP),是CRC主要易感事件,APC体突变见于>80%散发CRC,5q杂合性缺失(LOH)见于30%–40%的CRC。 APC蛋白. 腺瘤性结肠息肉(APC)病基因是 结直肠癌 抑癌基因,可在胚系和体系水平出现异常调节 …
