目标基因介绍

Catalytic subunit of AMP-activated protein kinase (AMPK), an energy sensor protein kinase that plays a key role in regulating cellular energy metabolism (PubMed:17307971, PubMed:17712357).
In response to reduction of intracellular ATP levels, AMPK activates energy-producing pathways and inhibits energy-consuming processes: inhibits protein, carbohydrate and lipid biosynthesis, as well as cell growth and proliferation (PubMed:17307971, PubMed:17712357).
AMPK acts via direct phosphorylation of metabolic enzymes, and by longer-term effects via phosphorylation of transcription regulators (PubMed:17307971, PubMed:17712357).
Regulates lipid synthesis by phosphorylating and inactivating lipid metabolic enzymes such as ACACA, ACACB, GYS1, HMGCR and LIPE; regulates fatty acid and cholesterol synthesis by phosphorylating acetyl-CoA carboxylase (ACACA and ACACB) and hormone-sensitive lipase (LIPE) enzymes, respectively (PubMed:7959015).
Promotes lipolysis of lipid droplets by mediating phosphorylation of isoform 1 of CHKA (CHKalpha2) (PubMed:34077757).
Regulates insulin-signaling and glycolysis by phosphorylating IRS1, PFKFB2 and PFKFB3 (By similarity).
Involved in insulin receptor/INSR internalization (PubMed:25687571).
AMPK stimulates glucose uptake in muscle by increasing the translocation of the glucose transporter SLC2A4/GLUT4 to the plasma membrane, possibly by mediating phosphorylation of TBC1D4/AS160 (By similarity).
Regulates transcription and chromatin structure by phosphorylating transcription regulators involved in energy metabolism such as CRTC2/TORC2, FOXO3, histone H2B, HDAC5, MEF2C, MLXIPL/ChREBP, EP300, HNF4A, p53/TP53, SREBF1, SREBF2 and PPARGC1A (PubMed:11554766, PubMed:11518699, PubMed:15866171, PubMed:17711846, PubMed:18184930).
Acts as a key regulator of glucose homeostasis in liver by phosphorylating CRTC2/TORC2, leading to CRTC2/TORC2 sequestration in the cytoplasm (By similarity).
In response to stress, phosphorylates 'Ser-36' of histone H2B (H2BS36ph), leading to promote transcription (By similarity).
Acts as a key regulator of cell growth and proliferation by phosphorylating TSC2, RPTOR and ATG1/ULK1: in response to nutrient limitation, negatively regulates the mTORC1 complex by phosphorylating RPTOR component of the mTORC1 complex and by phosphorylating and activating TSC2 (PubMed:14651849, PubMed:20160076, PubMed:21205641).
In response to nutrient limitation, promotes autophagy by phosphorylating and activating ATG1/ULK1 (PubMed:21205641).
In that process also activates WDR45/WIPI4 (PubMed:28561066).
Phosphorylates CASP6, thereby preventing its autoprocessing and subsequent activation (PubMed:32029622).
AMPK also acts as a regulator of circadian rhythm by mediating phosphorylation of CRY1, leading to destabilize it (By similarity).
May regulate the Wnt signaling pathway by phosphorylating CTNNB1, leading to stabilize it (By similarity).
Also acts as a regulator of cellular polarity by remodeling the actin cytoskeleton; probably by indirectly activating myosin (PubMed:17486097).
Also phosphorylates CFTR, EEF2K, KLC1, NOS3 and SLC12A1 (PubMed:12519745, PubMed:20074060).
Plays an important role in the differential regulation of pro-autophagy (composed of PIK3C3, BECN1, PIK3R4 and UVRAG or ATG14) and non-autophagy (composed of PIK3C3, BECN1 and PIK3R4) complexes, in response to glucose starvation (By similarity).
Can inhibit the non-autophagy complex by phosphorylating PIK3C3 and can activate the pro-autophagy complex by phosphorylating BECN1 (By similarity).

复苏
|
1)在37℃水浴中预热完全培养基。
2)将冻存管在 37℃水浴中解冻1-2分钟。
3)将冻存管转移到生物安全柜中,并用70%乙醇擦拭表面。
4)拧开冻存管管盖,将细胞悬液轻轻转移到含有9mL完全培养基的无菌离心管中。
5)在室温下以125g离心5-7分钟,弃上清。
6)用5mL的完整培养基重悬细胞沉淀,将细胞悬液转移到T25培养瓶中。
7)将细胞转移到37℃,5% CO2的培养箱中培养。
8)参考传代比例:1/2到1/3传代,2-5天长满。

传代
|
1)待培养瓶中细胞汇合度至80%-90%以上,可进行细胞传代。
2)将培养基、PBS、胰酶(0.25%Trypsin_EDTA Gibco 25200-056)等从4℃冰箱中拿出,置于37℃水浴中温度接近37℃时取出并在瓶子表面喷洒75%酒精后置于生物安全柜中。
3)从培养箱中取出待传代的培养瓶,瓶身喷洒75%酒精后置于生物安全柜中。
4)为避免冲散细胞,沿培养瓶上壁PBS润洗细胞,清洗细胞后弃去,T25加2mL。
5)加入对应体积的胰酶(T75加1.5mL,T25加0.5mL),并轻轻晃动瓶身使胰酶平铺满细胞底部。可根据实际情况适当增加或减少用量。约1-2min后大部分细胞脱落时,加入对应体积的完全培养基终止消化,并用5mL移液管轻轻吹打至细胞全部脱落。
6)将细胞悬液转移至15mL离心管,悬液300g离心5min,弃上清。
7)移取5mL完全培养基重悬细胞,按需求调整接种比例,并补充培养瓶中完全培养基,T75加至13-15mL,T25加至5mL,加1%双抗。
8)盖上瓶盖拧紧后轻轻晃动瓶身,使细胞混合均匀后置于37℃,5% CO4培养箱中。

细胞冻存
|
1)准备冻存液,并提前预冷。
2)确保待冻存的细胞满足冻存要求,用显微镜检查以下状态:健康的外观及形态特征、所处生长周期(对数晚期)、无污染或衰退迹象。
3)对细胞进行消化及离心处理(具体步骤参考传代培养流程)
4)按照每管1mL的量添加冻存液重悬细胞,吹打均匀后分装至冻存管。
5)将细胞放在程序降温盒中,在-80℃冰箱中冷冻。
6)后续将细胞转移到液氮罐中,以便长期储存。
