目的
2
探究SLC38A1通过促进谷氨酰胺运转激活PI3K/AKT信号传导促进肝细胞癌(hepatocellular carcinoma,HCC)的机制。
方法
2
通过生物信息学分析SLC38A1与HCC患者临床病理特征、预后的关系,并通过富集分析探究SLC38A1的功能。通过转染来沉默和过表达Huh-7细胞中SLC38A1,通过DRP-104抑制谷氨酰胺,通过LY294002抑制PI3K/AKT通路。采用CCK-8、EdU染色实验、划痕愈合实验、Transwell和谷氨酰胺试剂盒分别检测细胞活力、增殖、迁移、侵袭能力和谷氨酰胺浓度。采用 Western blot检测PI3K/AKT通路。
结果
2
HCC肿瘤样本中SLC38A1的mRNA和蛋白水平均高于正常组织(
P<
0.05),SLC38A1高表达的HCC患者的生存率显著低于SLC38A1低表达HCC患者(
P<
0.05)。SLC38A1高低表达与HCC患者的pT分期、pN分期、pM分期、生存
状态、免疫浸润之间存在相关性(
P<
0.05)。沉默SLC38A1后,HCC细胞中谷氨酰胺的摄取显著减少(
P<
0.001),抑制细胞活力、增殖、迁移、侵袭和PI3K/AKT通路(
P<
0.001)。过表达SLC38A1促进HCC细胞的增殖、迁移、侵袭、并激活PI3K/AKT通路(
P<
0.001),DRP-104抑制谷氨酰胺抑制HCC细胞和PI3K/AKT通路,并阻断SLC38A1过表达对HCC细胞和PI3K/AKT通路的促进(
P<
0.001)。抑制PI3K/AKT通路阻断过表达SLC38A1对 HCC细胞的促进作用(
P<
0.001)。
结论
2
SLC38A1 通过促进谷氨酰胺运转激活PI3K/AKT促进HCC细胞的增殖、迁移和侵袭。
Objective
2
To investigate the mechanism by which SLC38A1 promotes hepatocellular carcinoma (HCC) progression through glutamine transport-mediated activation of the PI3K/AKT signaling pathway. Methods Bioinformatics analysis was employed to assess the correlation between SLC38A1 expression and clinicopathological features/prognosis in HCC patients
with functional enrichment analysis of SLC38A1 conducted. SLC38A1 was silenced or over expressed
via
transfection in Huh-7 cells
with glutamine inhibited using DRP-104 and the PI3K/AKT pathway suppressed using LY294002. Cell viability
proliferation
migration
invasion
and glutamine concentration were evaluated using CCK-8
EdU staining
scratch wound healing assay
Transwell chamber assay
and glutamine assay kits
respectively. PI3K/AKT pathway activity was assessed by Western blotting.
Results
2
SLC38A1 mRNA and protein levels were significantly higher in HCC tumor tissues than in adjacent normal tissues
(P
<
0.05). HCC patients with high SLC38A1 expression exhibited significantly lower overall survival than those with low expression (
P
<
0.05). SLC38A1 expression correlated significantly with pathologic T-stage (pT)
N-stage (pN)
M-stage (pM)
survival status
and immune infiltration in HCC patients (
P
<
0.05). SLC38A1 silencing markedly reduced glutamine uptake in HCC cells (
P
<
0.001)
su
ppressing cell viability
proliferation
migration
invasion
and PI3K/AKT pathway activity (
P
<
0.001). Conversely
SLC38A1 overexpression promoted proliferation
migration
invasion
and PI3K/AKT activation (
P
<
0.001). DRP-104-mediated glutamine inhibition suppressed HCC cell malignancy and PI3K/AKT signaling while abolishing the oncogenic effects of SLC38A1 overexpression (
P
<
0.001). PI3K/AKT pathway inhibition blocked the pro-tumorigenic effects of SLC38A1 overexpression (
P
<
0.001).
Conclusion
2
SLC38A1 promotes proliferation
migration
and invasion in HCC by activating the PI3K/AKT pathway through enhanced glutamine transport.
