3-Thiatetradecanoic Acid is an activator of PPAR.
The peroxisome proliferator-activated receptors (PPARs) are transcription factors involved in fatty acid metabolism and energy homeostasis. The PPARs also play crucial roles in the control of cellular growth and differentiation.
In vitro: In BT4Cn cells, 3-thiatetradecanoic acid could activate all PPAR subtypes dose-dependently. In cell culture experiments, the PPARγ-selective ligand BRL49653 moderately inhibited growth of BT4Cn cells, while administration of 3-thiatetradecanoic acid led to a marked growth inhibition. Moreover, the administration of the PPARγ-selective antagonist GW9662 abolished BRL49653-induced growth inhibition, but only marginally reduced the effect of 3-thiatetradecanoic acid [1].
In vivo: Administration of 3-thiatetradecanoic acid increased mitochondrial and peroxisomal beta-oxidative capacity and carnitine palmitoyltransferase activity, but reduced free fatty acid and triacylglycerol levels in plasma compared to palmitic acid-treated rats and controls. 3-Thiatetradecanoic acid administration was able to affect the fatty acid composition in plasma and liver by increasing the amount of monoenes [2].
Clinical trial: A previous study described the clinical, hematological, and biochemical safety of 3-thiatetradecanoic acid. 3-Thiatetradecanoic acid was given as a single oral dose for 7 consecutive days. No significant changes were observed in the hematological or clinical chemical parameters in blood/urine. 3-Thiatetradecanoic acid did not induce significant changes in the blood lipids or free fatty acids, but it did lead to an increase in plasma concentration of Δ9 desaturated 3-thiatetradecanoic acid. 3-thiatetradecanoic acid was found to be safe and well tolerated [3].

我在做5RACE,选用TaKaRa公司的RNA反转录酶（RNaseH-），不知道这个酶好不好，有什么需要注意的。
没有序列识别的功能，他就是简单的催化相邻DNA链的5-P末端和3'-OH末端以磷酸二酯键结合的反应，需ATP作辅酶。 不仅可以催化粘性末端之间或平滑末端之间的DNA的连接，也催化DNA与RNA之间以及少数RNA之间的连接。
反转录酶（Reversetranscripatase）是以RNA为模板指导三磷酸脱氧核苷酸合成互补DNA（cDNA）的酶。哺乳类C型病毒的反转录酶和鼠类B型病毒的反转录酶都是一条多肽链。鸟类RNA病毒的反转录酶则由两上亚基结构。真核生物中也都分离出具有不同结构的反转录酶。
