Myostatin is a negative regulator of skeletal muscle growth. It plays an important role during myogenic differentiation.

肌肉生长抑制素是一种抑制动物骨骼肌生长发育的负调控因子，在肌细胞的形成过程中有着重要的生理功能。

Objective To study the effects of IFN-γ,TNF-α,IL-10and IL-12on the B7mRNA and protein expression of lymphocyte in experimental autoimmune myositis.

目的 探讨B7在实验性自身免疫性肌炎发病中的作用及γ干扰素、肿瘤坏死因子α、白细胞介素-10(IL-10)、IL-12对其的影响。

Expression analyses identified increased expression of numerous TGF-beta-related genes that regulate cell proliferation and survival and plausibly contribute to myxomatous valve disease.

他们注意到，多数效应器分子的表达增加降低了TGF-β的信号作用，包括可诱导TGF-β的H3基因、内皮素-1、组织抑制因子金属蛋白酶1、致骨形态学发生的蛋白和&调节细胞增生和存活可能还有促进粘液瘤性疾病的基因&。

The result showed that the main factors of multiplication of bud clumps are the basic medium, BA and NAA.

结果表明：影响丛生芽增殖的显著因子分别是基本培养基、细胞分裂素BA、生长素NAA。

Objective To investigate the roles of AngU ,fibrinolytic activity and transforming growth factor -fil (TGF-f31) in benign arteriolar nephrosclerosis due to primary hypertension.Methods 192 patients of primary hypertension were divided into 3 groups according to the degree of hypertension.

目的 通过测定192例原发性高血压患者及52例正常人尿转化生长因子-β1(TGF-β1)、血浆凝血酶原激活物抑制物-1(PAI-1)、血管紧张素Ⅱ含量，观察其在不同分级、不同肾损害程度的高血压患者的表达水平，以探讨其与高血压性肾损害发生发展的关系。

Conclusions-We suggest that the ontogenetically determined cardiomyocyte number may be an independent factor in the susceptibility to cardiac diseases. Through its profound impact on both cardiomyocyte replication and apoptosis, survivin may emerge as a promising new target for myocardial regeneration.

我们研究结果提示，个体特异性的心肌细胞数可能是心脏病易感性的独立预测因子，存活素通过对心肌细胞复制和凋亡的广泛影响，有望作为心肌再生的一个新靶点。

Methods Male Sprague Dawley rats were induced by ligating the anterior descending coronary artery and were divided into the 2nd, 4th, 8th, 12th and 21st week groups. Elastic fibers were evaluated in the infarct region using Masson trichrome staining, Uana orcein staining and image analysis. The expressions of TNFα and IL-1β were also detected by immunohistochemistry.

SD大鼠冠状动脉前降支结扎形成心肌梗死模型，于术后2、4、8、12、21周时，用Masson染色、Uana地衣红染色技术和免疫组织化学方法，分别观察梗死区弹性纤维和白细胞介素1β(IL-1β)、肿瘤坏死因子的变化，计算机图像分析系统作半定量分析。

OBJECTIVE: To study the interaction between tumor necrosis factor-α and osteoprotegerin on the apoptosis of osteoblastic cells.

目的：探讨肿瘤坏死因子α能否诱导成骨类细胞凋亡及骨保护素能否抑制其凋亡。

They were cultured for 48 hours,and the a mount of osteolytic factors such as TNF-a and IL-6 of each group was determined.

培养48h后，用ELISA测定细胞上清液中肿瘤坏死因子-a、白细胞介素-6含量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
