Published on July 21, 2012 a A research study led by the Peninsula College of Medicine and Dentistry, University of Exeter, and Boston University School of Medicine, in collaboration with a global consortium, has identified genetic markers that influence a protein involved in regulating oestrogen and testosterone levels in the bloodstream. The results, published online in PLoS Genetics, also reveal that some of the genetic markers for this protein are near genes related to liver function, metabolism and type 2 diabetes, demonstrating an important genetic connection between the metabolic and reproductive systems in men and women. The study was carried out in collaboration with the Framingham Heart Study and investigators from 15 international epidemiologic studies participating in the Cohorts for Heart and Aging Research in Genetic Epidemiology (CHARGE) consortium. Sex hormone binding globulin (SHBG) is the key protein that carries testosterone and oestrogen in the bloodstream in both men and women. As the main carrier of these sex hormones, SHBG helps to regulate their effects in different tissues and organs in the body. In addition to effects on reproduction in men and women through regulation of sex hormones, SHBG has been linked to many chronic diseases including type 2 diabetes and hormone-sensitive cancers such as breast and prostate. Previous family studies have demonstrated that approximately 50 per cent of the variation in SHBG concentrations in the bloodstream is inherited from parents, suggesting that SHBG levels are under significant genetic control. However, little has been known about the specific genes that influence SHBG levels.

若香港禽流感疫苗失效 台灣病毒變種是否也…?
疫苗失效 今冬禽流感高發期 星島日報 – 2012年7月23日星期一上午6:30 疫苗失效 今冬禽流感高發期 (綜合報道)(星島日報報道)本港過去兩年拾到帶有H5N1禽流感病毒的死雀數目有所增加。微生物學專家袁國勇警告,本港現時使用的禽流感疫苗,追不上病毒變種,已經失去效用,預計今年冬天是禽流感高發期,「通常病發都在冬天,但最近七月仍在雀仔街發現個案,種種蛛絲馬迹都告訴大家,今年會是高發期。」
袁國勇指基因變種 他呼籲市民千萬不要接觸死雀,政府亦要加強監察及進行公眾教育。 香港大學微生物學系講座教授袁國勇指,本港現時使用的H5N2禽流感疫苗已追不上基因變種,「現時本港最流行的禽流感基因是2.3.2.1,但本港禽畜採用的禽流感疫苗叫H5N2,(效力)連零都不如,是H5N1以外的東西,其實已經完全失效。」他表示,南中國現時採用的疫苗製於哈爾濱,其基因組別是2.3.4,效力亦已開始下跌,「其實這一點也不出奇,因為季節性流感每隔幾年都會轉一轉。」 他又指,本港這兩年拾到帶有H5N1禽流感病毒的死雀有所增加,「而且它們都是屬於2.3.2.1,不是2.3.4;早前出現的人類感染個案亦屬於2.3.2.1。所以今年冬天形勢不妙,應該會是高發期。」他表示,現時本港仍未有疫苗可以針對2.3.2.1,「聽說哈爾濱原本希望於七月推出新疫苗,但現在還未有,可能有些阻礙;而由於本港沒有製造業,我們只可以把結果測試出來,疫苗則讓其他地方製造。」
密切監察候鳥家禽 袁國勇強調,要控制禽流感,最重要是對候鳥、水禽以及家禽進行監察,以知道現時在香港及南中國最重要的H5N1組別屬於那一個基因組別,從而作出應對策略。他說:「以H5N1禽流感為例,我們可以在候鳥中發現該病毒,而水禽,即鴨鵝可能會與他們有交叉感染,水禽又可能把H5N1傳給雞,要知道人類食很多雞,又接觸很多雞,於是便可能令我們受到感染;不過暫時都不是人傳人,主要都是禽畜傳人。」記者 張聲慧
