【預期用途】
尼古丁(Nicotine)是煙草中的主要生物堿,是導致吸煙成癮的物質(zhì)動因,也是評價人體攝入煙草煙霧的常用指標。但因為尼古丁半衰期短,無法作為標志物檢測,其代謝物可替寧因為半衰期長作為吸煙和戒煙的標志物。
本品采用競爭抑制法和膠體金免疫層析技術,用于快速定性檢測人體唾液中的可替寧,適用于評價煙草煙霧攝入的初步篩查。

前列腺癌是男性常見惡性腫瘤,但目前還缺乏有效的診斷方法區(qū)分“高危害”與“非轉(zhuǎn)移性惰性”(Indolent)前列腺癌。PTEN是前列腺癌中發(fā)生突變的腫瘤抑制基因,約有70%的轉(zhuǎn)移性前列腺癌病人呈現(xiàn)PTEN缺失或PI3K/AKT信號通路異常激活;但是小鼠前列腺上皮細PTEN特異性敲除卻不能形成高轉(zhuǎn)移性前列腺癌,因此尋找及鑒定能夠協(xié)同PTEN缺失促進前列腺癌轉(zhuǎn)移的關鍵信號通路或因子,可以為臨床的診斷和治療提供新的靶點和思路。 課題組發(fā)現(xiàn),肝癌細胞通過分泌一種特定細胞因子吸引巨噬細胞成為自己的“幫兇”,從而存活下來,趙斌課題組建立了一種新型的小鼠活體肝細胞基因編輯體系,這一新型的體系可以“定向”讓個別正常的肝細胞先行癌變,并精確模仿肝癌的發(fā)展進程。“絕大多數(shù)的癌癥都是由個別正常的體細胞突變而來,新型技術揭示出,當*個細胞癌變時,腫瘤是怎樣一步步發(fā)生發(fā)展的。”趙斌介紹。 課題組發(fā)現(xiàn),肝癌細胞通過分泌一種特定細胞因子吸引巨噬細胞成為自己的“幫兇”,從而存活下來。研究人員介紹,并巨噬細胞是人體內(nèi)一種重要的免疫細胞,該細胞會定向識別吞噬病原體,但在單個體細胞初期癌變的階段,巨噬細胞卻能夠抑制免疫細胞,腫瘤細胞從而成功逃過免疫監(jiān)視,避免被清除。 “具有識別和對抗癌細胞功能的免疫細胞‘繳械投降’,是腫瘤細胞得以進一步發(fā)展的重要原因。在肝癌發(fā)生的起始階段,課題組觀察到了這種現(xiàn)象并找到了 。一直以來,CB1結(jié)構成謎,但它卻是治療疼痛、炎癥、肥胖癥以及藥物濫用的潛在藥物靶點,不少相關藥物的研究都繞不過它,甚至還有不少研發(fā)的藥物因為缺乏CB1的結(jié)構信息,導致藥物的專一性差而對人體產(chǎn)生副作用。CB1是人的中樞神經(jīng)系統(tǒng)中表達量zui高的G蛋白偶聯(lián)受體(GPCR)之一。并巨噬細胞是人體內(nèi)一種重要的免疫細胞,該細胞會定向識別吞噬病原體,但在單個體細胞初期癌變的階段,巨噬細胞卻能夠抑制免疫細胞,腫瘤細胞從而成功逃過免疫監(jiān)視,避免被清除。

Prostate cancer is a common malignancy in men, but there is a lack of effective diagnostic methods to distinguish between "high-risk" and "non-metastatic" (Indolent) prostate cancer. PTEN is one of the most widespread tumor suppressor genes in prostate cancer. Approximay 70% of patients with metastatic prostate cancer have PTEN deletion or abnormal activation of PI3K / AKT signaling pathway. However, PTEN-specific knockout of mouse prostate epithelium can not form high Metastatic prostate cancer. Therefore, finding and identifying key signaling pathways or factors that can cooperate with PTEN deletion in promoting prostate cancer metastasis can provide new targets and ideas for clinical diagnosis and treatment. The research team found that liver cancer cells through the secretion of a specific cytokine to attract macrophages become their own "accomplice" to survive, Zhao Bin task force to establish a new mouse living hepatocyte gene editing system, this new System can be "targeted" for individual normal liver cells advance carcinogenesis, and accuray mimic the development of liver cancer. "The vast majority of cancers are caused by mutations in individual normal somatic cells, and newer technologies reveal how tumors develop step by step as the first cell becomes cancerous," said Zhao Bin. Task force found that liver cancer cells by secreting a specific cytokine to attract macrophages become their own "accomplice" and thus survive. The researchers introduced and macrophages is an important immune cells in the human body, the cells will be targeted to identify phagocytic pathogens, but in the initial stage of the somatic cells of an individual, macrophages can inhibit immune cells, tumor cells and thus successfully escape Immunization surveillance to avoid being cleared. "With the immune cells that recognize and fight against cancer cells," surrender "is an important reason for the further development of tumor cells, which was observed and found in the initial stage of liver carcinogenesis. However, it is a potential drug target for the treatment of pain, inflammation, obesity and drug abuse. Many related drug research has not been able to get around it. There are even many research and development of drugs because of the lack of CB1 structural information, Leading to poor specificity of the drug and side effects on the human body.CB1 is one of the highest expression of G protein-coupled receptors (GPCR) in human central nervous system and macrophages are an important immune cells in the human body, The cell directs the phagocytosis of pathogens, but during the initial stage of somatic cell myxogenesis, macrophages inhibit immune cells and tumor cells from escaping immune surveillance to avoid being cleared.
