The molecular techniques were used to analyse tyrosine phosphorylation of JAK2 and STAT3 in leptin receptor overpression cell lines and SH2-Bβ knockout (SH2-Bβ-/-) mice. The serum level of leptin in SH2-Bβ mice was measured by ELISA. The results showed that SH2-Bβ dramatically enhanced the leptin-stimulated tyrosine phosphorylation of JAK2 and STAT3 in vitro. Leptin-stimulated activation of JAK2 and phosphorylation of STAT3 were significantly impaired in hypothalamus of SH2-Bβ-/- mice. The fasting and postprandial serum levels of leptin and body weight were markedly increased in SH2-Bβ-/- mice. Therefore, SH2-Bβ is an endogenous enhancer of leptin sensitivity and regulates body weight via leptin/ JAK2/STAT3 pathway.

Background The human transforming growth factor beta-induced gene (TGFBI) is the first determined pathogenic gene to corneal dystrophy.But the molecular genetic mechanism is completely unknown.The study of concerning role of TGFBI is very important for us understand the physiological function of cornea,and the pathogenesis of corneal dystrophy.Objective The vector of human transforming growth factor beta-induced gene (TGFBI) in eukaryotic expression was constructed and transfected into the human corneal epithelial cells in order to explore its influence on the growth of human corneal epithelial cells.Methods Total RNA was extracted from normal donor cornea tissue and cDNA was obtained by reverse transcription.TGFBI cDNA was synthesized by reverse transcription-PCR and cloned into pCMV-N-HA vector and identified by sequencing with PCR and EcoRV,XhoI double restriction endonuclease.The cells were grouped into recombinant pCMV-N-HA-TGFBI plasmid group,pCMVN-HA plasmid group,non-transfected group and pGFP-C2 transfected group.The recombinant pCMV-N-HA-TGFBI plasmid was transfected to human corneal epithelial cells and identified by observing the expression of enhanced green fluorescence protein(EGFP) in the cells.The TGFBI mRNA and proteins were harvested from the cells for real-time PCR analysis and Western blot assay respectively in 58 hours after transfection.The growth of the transfected cells was assessed by Cell Counting Kit-8.The expressions of matrix metalloproteinase(MMP) and tissue inhibitors of matrix metalloproteinase (TIMP) proteins and their mRNA in transfected cells were detected using SYBR fluorescence realtime PCR analysis and Western blot assay.Results The sequencing result of pCMV-N-HA-TGFBI positive clone plasmid showed that amplified TGFBI eDNA inserted into the vector at the correct sequence.EGFP was expressed in transfected cells in 48 hours after transfer of pGFP-C2 with the transfer efficacy 70％.The expression intensity of TGFBI mRNA was significantly higher in recombinant pCMV-N-HA-TGFBI plasmid group compared with pCMV-N-HA plasmid group and non-transfected group,and TGFBI protein was expressed in recombinant pCMV-N-HA-TGFBI plasmid group.No significant difference was found in the A450value among recombinant pCMV-N-HA-TGFBI plasmid group,pCMV-N-HA plasmid group and non-transfected group ( F=3.34,P＞0.05 ).The mRNA level of MMP1,MMP3in the transfected cells was significant elevated but that of TIMP1 was declined in the recombinant pCMV-N-HA-TGFBI plasmid group compared with pCMV-N-HA plasmid group and non-transfected group (all P ＜ 0.05 ).Meanwhile,the expressions of MMP1,MMP3 and TIMP1 proteins appeared the same tendency( all P＜0.05).Conclusions Eukaryotic expression vector harboring human TGFBI eDNA can be successfully constructed and efficiently overexpressed in human corneal epithelial cells.TGFBI gene is involved in the physical and pathological conditions of human corneal epithelial cells by regulating the activity of MMP1,MMP3 and TIMP1.The results offer a new approach for the study of the role of TGFBI in pathogenesis of corneal transparency.

OBJECTIVE To study the pharmacokinetics of heat shock protein 65-mucin 1 (HSP65-MUC1) recombinant fusion protein vaccine in Macaca mulatta monkeys and tumor-bearing mice. METHODS HSP65-MUC1 was labeled by radioactive isotope 125I. M. mulatta monkeys were randomly divided into sc and iv administration groups. Simultaneously, sc administration group was designed as a multiple dose group in which M. mulatta monkeys were sc given [ 125I] HSP65-MUC1 40 μg·g-1, once every 2 weeks for a total of 3 times. Size exclusion chromatography ( SEC) was used to determine concentrations of HSP65-MUC1 in serum samples. The tumor-bearing mice were randomly divided into 0.5, 1.5, 4, 8 and 24 h groups. Mice were sc given [125I] HSP65-MUC1 550 μg·kg-1, tissues were collected and tissue distribution of [125I] HSP65-MUC1 in tumor-bearing mice was studied using trichloroacetic acid (TCA) precipitation method. RESULTS The absolute bioavailability of [125I]HSP65-MUC1 was 38.33% after M. mulatta monkeys were sc given [125I]HSP65-MUC1. In multiple dose group, concentrations of [125I]HSP65-MUC1 after the third dose administration was compared to that of the first dose administration. The accumulation factor (AUC3/AUC1) was 1.17 ±0.25. Distribution of [ 125I]HSP65-MUC1 was significantly different compared with general polypeptide and protein drugs after sc in tumor-bearing mice. The concentration in lymph nodes was the highest. The concentration in other immune tissues, such as thymus and spleen, were not relatively high, but their declined tendency was slow after reaching the peak concentration (cmax ). However, the concentrations in the serum and some other tissues with a large blood volume, such as the heart, liver, and lung, were relatively low and declined quickly after reaching cmax. Its level in the tumor was not very high. [125 I] HSP65-MUC1 was excreted mainly by the kidneys. CONCLUSION The bioavailability of [125I]HSP65-MUC1 is 38.33% after sc administration in M. mulatta. After multiple-dose administration, the vaccine does not accumulate in the body, whose concentration is the highest in lymph nodes after [1251] HSP65-MUC1 was sc given in tumor-bearing mice, but is not very high in tumor. Besides, the vaccine declined tendency is slow after reaching cmax in immune tissues such as thymus and spleen compared with other tissues with a large blood volume.
