Embodiment Construction

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The experimental methods for which specific conditions are not indicated in the preferred embodiments are usually carried out according to conventional conditions, or according to the conditions suggested by the manufacturer.

[0033] In a preferred embodiment, the coding DNA sequence of the shRNA that inhibits ALDH1A3 gene expression is any one of the following three sequences (the underlined part is the loop sequence):

[0034] 1: gctgtattagaaccctcagatctc cgggatccaa gagatctgagggttctaatacagcttttttg (SEQ ID No. 1);

[0035] 2: gccgaatacacagaagtgaaactc cggatccaa gagtttcacttctgtgtattcggcttttttg (SEQ ID No. 2);

[0036] 3: aaccaatactgaagttcaactc cgggatccaa gagttgaacttcagtattggttgcttttttg (SEQ ID No. 3).

[0037] The construction method of ALDH1A3 gene shRNA expression vector comprises the following steps:

[0038] 1) Synthesize the foll...

Abstract

The invention discloses applications of aldehyde dehydrogenases (ALDH) 1A3 and an encoding gene thereof as a target for preventing and treating invasion and metastasis of colorectal cancer and as an independent prognostic determination factor for the colorectal cancer, and also an application of an expression down-regulation agent, an activity inhibitor and an over-expression effect inhibitor of the ALDH 1A3 in preparation of medicines for reversing the invasion and metastasis of colorectal cancer. The applications have important significance of preventing and treating the invasion and metastasis of colorectal cancer and prognostic determination of the colorectal cancer.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and relates to the application of acetaldehyde dehydrogenase 1A3 and its coding gene as a target for preventing or treating tumor invasion and metastasis. Background technique [0002] Colorectal cancer is a serious threat to human health, and invasion and metastasis are the most important cause of death in colorectal cancer patients. Therefore, it is of great clinical significance to explore the targets and molecules targeting the invasion and metastasis of colorectal cancer, and then develop related therapeutic drugs. [0003] The human acetaldehyde dehydrogenase (Aldehydehydrogenases, ALDH) family contains 19 subtypes, and different ALDH subtypes have different subcellular locations (including nucleus, mitochondria and cytoplasm) and different functions. Previously, it was believed that this family could participate in the regulation of many important pathophysiological processes, includi...
