目的
2
探讨健脾中药复方胃肠安(WCA)通过多聚嘧啶结合蛋白3(PTBP3)调控分化抑制因子1(
Id1
)mRNA选择性剪接抑制胃癌细胞恶性进展的作用机制。
方法
2
利用
PTBP3
基因被稳定沉默的人胃癌细胞MKN45,建立相应的裸小鼠皮下移植瘤模型。模型裸小鼠随机分为MKN45细胞0.9%氯化钠溶液组(NC组,作为对照),MKN45细胞WCA组(NC-WCA组),沉默
PTBP3
MKN45细胞0.9%氯化钠溶液组(shPTBP3组),沉默
PTBP3
MKN45细胞WCA组(shPTBP3-WCA组),每组6只。每日灌胃给予相应干预,共28 d。考察WCA对移植瘤生长、PTBP3及
Id1
异构体表达的影响。采用苏木精-伊红(HE)染色法和Ki67染色法分别观察肿瘤组织形态和肿瘤细胞比例。采用实时荧光定量逆转录聚合酶
链式反应(RT-qPCR)法和Western blot法检测移植瘤细胞内PTBP3、Id1a、Id1b蛋白和mRNA表达。
结果
2
与NC组相比,NC-WCA组、shPTBP3组、shPTBP3-WCA组小鼠瘤体质量均减轻,差异有统计学意义(
P
<
0.05)。HE和Ki67染色提示沉默
PTBP3
和WCA干预均可抑制小鼠MKN45肿瘤细胞增殖能力。RT-qPCR和Western blot结果显示,与NC组相比,沉默
PTBP3
和WCA干预均能使
Id1a
mRNA表达减少,
Id1b
mRNA表达增加,差异均有统计学意义(
P
<
0.05);在沉默
PTBP3
的模型裸小鼠中,WCA干预后
Id1a
mRNA表达减少,
Id1b
mRNA表达增加,差异均有统计学意义(
P
<
0.001);与NC组相比,沉默
PTBP3
和WCA干预均能下调Id1a表达(
P
<
0.05),并上调Id1b表达(
P
<
0.001),其蛋白表达变化与mRNA表达变化一致。
结论
2
PTBP3能调控
Id1
异构体的选择性剪接,中药复方WCA通过PTBP3调控
Id1
的选择性剪接,使Id1a表达下调、Id1b表达上调,从而抑制胃癌细胞恶性进展。
Objective
2
To explore the mechanism of strengthening spleen traditional Chinese medicine compound Weichang'an (WCA) in inhibiting malignant progression of gastric cancer cells through polypyrimidine tract-binding protein 3 (PTBP3) regulating alternative splicing of inhibitor of differentiation 1 (
Id1
) mRNA.
Methods
2
Using the human gastric cell line MKN45 that has been stably silenced for the
PTBP3
gene, a corresponding nude mouse subcutaneous tumor transplantation model was established. The model nude mice were randomly divided into the MKN45 cell 0.9% sodium chloride solution group (NC group, as control), the MKN45 cell WCA group (NC-WCA group), the
PTBP3
silenced MKN45 cell 0.9% sodium chloride solution group (shPTBP3 group), and the
PTBP3
silenced MKN45 cell WCA group (shPTBP3-WCA group), with 6 mice in each group. The corresponding interventions were administered by intragastric administration daily for a total of 28 d. The effects of WCA on the growth of transplanted tumors, expressions of PTBP3 and
Id1
isomers were investigated. The morphology of the tumor tissue and the proportion of tumor cells were observed by hematoxylin-eosin (HE) staining and Ki67 staining, respectively. Fluorescence quantitative reverse transcription polymerase chain reaction (RT-qPCR) and Western blot were used to detect the protein and mRNA expression of PTBP3, Id1a and Id1b in transplanted tumor cells.
Results
2
Compared with the NC group, the tumor weights of mice in the NC-WCA group, the shPTBP3 group, and the shPTBP3-WCA group all decreased, and the differences were statistically significant (
P
<
0.05). The HE and Ki67 staining results indicated that both silencing
PTBP3
and WCA intervention could inhibit the proliferation ability of mouse MKN45 tumor cells. The results of RT-qPCR and Western blot showed that compared with the NC group, both silencing
PTBP3
and WCA intervention could reduce the expression of
Id1a
mRNA and increase the expression of
Id1b
mRNA, and the differences were statistically significant (
P
<
0.05); in the model nude mice with silenced
PTBP3
, after WCA intervention, the expression of
Id1a
mRNA decreased and the expression of
Id1b
mRNA increased, and the differences were statistically significant (
P
<
0.001); compared with the NC group, both silencing
PTBP3
and WCA intervention could down-regulate the expression of Id1a (
P
<
0.05) and up-regulate the expression of Id1b ((
P
<
0.001), and the protein expression changes were consistent with the mRNA expression changes.
Conclusions
2
PTBP3 can regulate the alternative splicing of
Id1
isomers, and the traditional Chinese medicine compound WCA could regulate the alternative splicing of
Id1
through PTBP3, which could down-regulate the e
xpression of Id1a and up-regulate the expression of Id1b, thereby inhibit the malignant progression of gastric cancer cells.
