Resistin, a product of the RSTN gene, is a peptide hormone belonging to the class of cysteine-rich secreted proteins which is termed the RELM family, and is also described as ADSF and FIZZ3 . Human resistin contains 108 amino acids as a prepeptide, and its hydrofobic signal peptide is cleaved before its secretion. Resistin circulates in human blood as a dimeric protein consisting of two 92 amino acid polypeptides, which are disulfide-linked via Cys26.
Mouse resistin, specifically produced and secreted by adipocyte, acts on skeletal muscle myocytes, hepatocytes and adipocytes themselves so that it reduces their sensitivity. Steppan et al. have suggested that resistin suppresses the ability to stimulate glucose uptake. They have also suggested that resistin is present at elevated levels in blood of obese mice, and is down regulated by fasting and antidiabetic drugs. Way et al., on the other hand, have found that resistin expression is severly suppressed in obesity and is stimulated by several antidiabetic drugs.
Other studies have shown that mouse resistin increases during the differentiation of adipocytes, but it also seems to inhibit adipogenesis. In contrast, the human adipogenic differentiation is likely to be associated with a down regulation of resistin gene expression.

抵抗素是RSTN基因的产物，是一种肽激素，属于富含半胱氨酸的分泌蛋白类，被称为RELM家族，也被描述为ADSF和FIZZ3。人抵抗素含有108个氨基酸的前肽，其疏水信号肽在分泌前被切割。抵抗素以二聚体蛋白的形式在人体血液中循环，该二聚体蛋白由两个 92 个氨基酸的多肽组成，它们通过 Cys26 二硫键连接。
由脂肪细胞特异性产生和分泌的小鼠抵抗素作用于骨骼肌肌细胞、肝细胞和脂肪细胞本身，从而降低它们的敏感性。 Steppan 等人。已经表明抵抗素抑制刺激葡萄糖摄取的能力。他们还提出，肥胖小鼠血液中的抵抗素水平升高，并且通过禁食和抗糖尿病药物下调。另一方面，Way 等人发现，抵抗素的表达在肥胖症中受到严重抑制，并受到几种抗糖尿病药物的刺激。
其他研究表明，小鼠抵抗素在脂肪细胞分化期间增加，但它似乎也抑制脂肪生成。相反，人类脂肪形成分化可能与抵抗素基因表达的下调有关。

It is recommended to reconstitute the lyophilized Resistin in sterile 18MΩ-cm H₂O at a concentration of 100µg/ml, which can then be further diluted to other aqueous solutions.

建议在无菌 18MΩ-cm H2O 中以 100µg/ml 的浓度重构冻干的 Resistin，然后可以将其进一步稀释成其他水溶液。

Store lyophilized protein at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.
