Activation of SAPKs/JNKs and p38s In Vitro

some of the stimuli known to recruit both the SAPKs/JNKs and p38s. In general, the same stimuli that activate the SAPKs/JNKs will also activate the p38s. One exception is ischemia-reperfusion. In this instance, the SAPKs/JNKs are activated exclusively

Assay of Mammalian S-Adenosylmethionine Decarboxylase Activity

S -adenosylmethionine decarboxylase (AdoMetDC; EC 4.1 1.50) catalyzes the conversion of S -adenosylmethionine to S -5′-deoxyadenosyl-(5′)-3-methylthiopropylamine (decarboxylated S-adenosylmethionine) and CO2 . The enzyme is unusual

吉田肉瘤 Yoshida＇s sarcoma

白鼠的移植性肉瘤，属腹水肿瘤。吉田富三（ 1943）在使用ο -氨基偶氮甲苯及三氧化二砷的致癌实验中发现了一只白鼠得此肉瘤，现仍在继续移植中。从其细胞的性状来看，可以认为是来源于常在腹腔内的单核细胞。虽因宿主白鼠的种系而有差异，但移植率是很高的。宿主的存活期短，平均为 12天。将腹水稀释，即使用显微镜手术采得一个细胞也能移植。用无细胞的滤液不能移植，因此也不能否定病毒为其原因。对鼷鼠进行异种移植时，在一定时期是增殖的，但 10天后细胞便消失，而动物不死。吉田肉瘤移植后大量出现具有 38—
