  PLA2[1]

• 体外研究: 蜂毒肽是一种免疫相关的来自蜂毒的PLA2刺激肽,可增加高分子量酶的活性[1]。蜂毒肽是来自蜂毒的细胞毒性肽。蜂毒肽对A2780CR和A2780细胞均显示出毒性,IC50值分别为4.5和6.8μg/ mL。蜂毒肽具有天然抗菌,抗病毒和抗炎特性。它还被证明在几种不同的癌细胞系中具有多种抗癌作用,包括胃癌,乳腺癌,卵巢癌,肝癌,前列腺癌,宫颈癌和肺癌细胞系。 Melittin,一种两亲性溶血肽,发挥其潜在的抗癌作用的机制包括抑制细胞增殖,诱导细胞凋亡和直接坏死。蜂毒肽还可以通过抑制PI3K/Akt/mTOR信号通路来预防EGF诱导的细胞侵袭,但这主要与乳腺癌细胞有关[2]。
• 细胞实验: 通过反相液相色谱法从蜂毒中纯化蜂毒肽，并在无菌水中重构以形成1mg / mL的储备溶液，然后在-20℃储存直至需要进行分析。通过Alamar Blue（AB）细胞活力试剂评估细胞活力。将A2780和A2780CR细胞以1×10 4个细胞/孔接种在96孔板中，并在37℃和5％CO 2下在潮湿气氛中孵育24小时。在该温育期后，在100μL培养基中用各种浓度的0.5％至14μg/ mL的蜂毒肽处理细胞，并在37℃和5％CO 2下再孵育24小时。 1％（v / v）的Triton X和细胞培养基分别用作阳性和阴性对照。此后，以10％（v / v）的终浓度加入AB，并将所得混合物在37℃和5％CO 2下再温育4小时。然后，在560nm的激发波长下读板，在SpectraMax M3酶标仪上记录590nm的发射。通过将它们表示为相对于平均阴性对照值的百分比，将背景校正的荧光读数转换为每个测试孔的细胞活力数据[2]。
