| 目标基因介绍 | Multifunctional protein with controversial molecular function which plays an important role in cell protection against oxidative stress and cell death acting as oxidative stress sensor and redox-sensitive chaperone and protease (PubMed:17015834, PubMed:20304780, PubMed:18711745, PubMed:12796482, PubMed:19229105, PubMed:25416785, PubMed:26995087, PubMed:28993701). It is involved in neuroprotective mechanisms like the stabilization of NFE2L2 and PINK1 proteins, male fertility as a positive regulator of androgen signaling pathway as well as cell growth and transformation through, for instance, the modulation of NF-kappa-B signaling pathway (PubMed:12612053, PubMed:15502874, PubMed:14749723, PubMed:17015834, PubMed:21097510, PubMed:18711745). Has been described as a protein and nucleotide deglycase that catalyzes the deglycation of the Maillard adducts formed between amino groups of proteins or nucleotides and reactive carbonyl groups of glyoxals (PubMed:25416785, PubMed:28596309). But this function is rebuted by other works (PubMed:27903648, PubMed:31653696). As a protein deglycase, repairs methylglyoxal- and glyoxal-glycated proteins, and releases repaired proteins and lactate or glycolate, respectively. Deglycates cysteine, arginine and lysine residues in proteins, and thus reactivates these proteins by reversing glycation by glyoxals. Acts on early glycation intermediates (hemithioacetals and aminocarbinols), preventing the formation of advanced glycation endproducts (AGE) that cause irreversible damage (PubMed:25416785, PubMed:28013050, PubMed:26995087). Also functions as a nucleotide deglycase able to repair glycated guanine in the free nucleotide pool (GTP, GDP, GMP, dGTP) and in DNA and RNA. Is thus involved in a major nucleotide repair system named guanine glycation repair (GG repair), dedicated to reversing methylglyoxal and glyoxal damage via nucleotide sanitization and direct nucleic acid repair (PubMed:28596309). Protects histones from adduction by methylglyoxal, controls the levels of methylglyoxal-derived argininine modifications on chromatin (PubMed:30150385). Able to remove the glycations and restore histone 3, histone glycation disrupts both local and global chromatin architecture by altering histone-DNA interactions as well as histone acetylation and ubiquitination levels (PubMed:30150385, PubMed:30894531). Displays a very low glyoxalase activity that may reflect its deglycase activity (PubMed:22523093, PubMed:31653696, PubMed:28993701). Eliminates hydrogen peroxide and protects cells against hydrogen peroxide-induced cell death (PubMed:16390825). Required for correct mitochondrial morphology and function as well as for autophagy of dysfunctional mitochondria (PubMed:19229105, PubMed:16632486). Plays a role in regulating expression or stability of the mitochondrial uncoupling proteins SLC25A14 and SLC25A27 in dopaminergic neurons of the substantia nigra pars compacta and attenuates the oxidative stress induced by calcium entry into the neurons via L-type channels during pacemaking (PubMed:18711745). Regulates astrocyte inflammatory responses, may modulate lipid rafts-dependent endocytosis in astrocytes and neuronal cells (PubMed:23847046). In pancreatic islets, involved in the maintenance of mitochondrial reactive oxygen species (ROS) levels and glucose homeostasis in an age- and diet dependent manner. Protects pancreatic beta cells from cell death induced by inflammatory and cytotoxic setting (By similarity). Binds to a number of mRNAs containing multiple copies of GG or CC motifs and partially inhibits their translation but dissociates following oxidative stress (PubMed:18626009). Metal-binding protein able to bind copper as well as toxic mercury ions, enhances the cell protection mechanism against induced metal toxicity (PubMed:23792957). In macrophages, interacts with the NADPH oxidase subunit NCF1 to direct NADPH oxidase-dependent ROS production, and protects against sepsis (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。 | ||
