分析表明，该上游序列的转录起始位点位于第3255位G碱基处，没有明显的TATA-box和CAAT-box，但含有CCAAT-binding factor、GC-box等重要的转录因子结合位点，以及热激应答元件HSE和GATA元件等启动子顺式调控元件。

We aim to screen and identify the key potential trans-factors during hemoglobin switch. We firstly analyzed differential expression of mRNAs in erythroid induction cultures of CD34+ cells derived from normal umbilical cord blood, adult bone marrow, and bone marrow of a heterocellular hereditary persistence of fetal hemoglobin patient. We identified ZF (HCF-binding transcription factor, Zhangfei) and SH3GLB1(SH3-domain GRB2-like endophilin B1) that had differential expression in the above three cultures. Furthermore, we confirmed the different expression of the above two genes by quantitative real-time PCR.

为鉴别影响珠蛋白基因表达和开关的新的重要调节因子，我们首先分析了人脐带血、正常成人骨髓和异细胞型胎儿血红蛋白持续存在综合症患者骨髓细胞红系诱导培养物中基因表达的差异，发现ZF(HCF-binding transcription factor，Zhangfei)和SH3GLB1（SH3-domain GRB2-like endophilin B1）在这三种不同来源的红细胞内具有显著的表达差异，并通过实时定量PCR方法验证了差异的真实性。

Objective To investigate the dynamic expression of insulin-like growth factor 1 receptor in the posterior retina, refractive error and eye axial length after intravitreous injection of IGF-1R antisense oligonucleotides; to study the role of IGF-1R in the development of form-deprivation myopia in the guinea pig. Methods Sixty-four 3-week-old guinea pigs were included in the study.

Fibroblast growth factor 21（FGF21）is a novel fatty metabolic regulator. FGF21 mRNA is most abundantly expressed in liver. FGF21 contribute to fat metabolism, as well as ketogenic responses in liver,and it can promote the uptake of glucose, promote insulin secretion, delaying the development of tumors and other function.
