HDAC6作为组蛋白脱乙酰化酶家族一员通过微管去乙酰化和HSP90的去乙酰化调控基因转录，改变细胞的运动能力从而参与肿瘤发生发展和肿瘤的转移以及肿瘤血管的生成。

To prepare recombinant fox growth hormone, we amplified its cDNA from silver fox pituitary tissue by RT-PCR and cloned into yeast shuttle vector pPIC9K down stream of α-factor signal peptide sequence by SnaB I and Not I restriction sites. The recombinant secretion vector pPIC9K/fGH, linearized by Sal I, was transformed into histidine-deficient Pichia pastoris strain GS115 by electroporation.

为制备重组狐狸生长激素，采用RT-PCR方法，从银狐垂体中扩增fGH cDNA基因，利用SnaB I和Not I位点将fGH基因插入到酵母分泌型表达载体pPIC9K中α-因子信号肽的下游，构建成fGH基因的酵母分泌型表达载体pPIC9K/fGH，载体经Sal I酶切线性化后，通过电转移将线性化的pPIC9K/fGH转化到组氨酸缺陷型酵母宿主菌GS115中。
