〔編譯陳成良/綜合報導〕胰臟癌難以治療,其中一個原因是腫瘤內的癌細胞並不完全相同,有些生長侵略性較強,有些則相對緩慢。美國研究團隊發現,名為MYC的基因可能是維持部分胰臟癌細胞高度惡性的重要因素;在細胞實驗中,抑制MYC活性後,部分侵略性較強的癌細胞竟轉變為另一種侵略性較低的型態。
科技媒體《SciTechDaily》報導,這項由紐約大學朗格尼健康中心(NYU Langone Health)研究團隊進行的研究,刊登於《自然遺傳學》(Nature Genetics)。團隊分析56名患者的腫瘤樣本,檢視超過44萬個細胞,藉此了解同一個腫瘤內不同癌細胞的特性。
研究團隊將胰臟癌細胞主要分為「基底型」與「經典型」。基底型通常具有較強的侵略性,經典型則相對較不具侵略性。兩種型態可能同時存在於同一個腫瘤內,代表癌細胞並非完全一致。
研究人員發現,MYC基因在侵略性較強的癌細胞中特別活躍。在細胞實驗中,抑制MYC活性後,部分基底型癌細胞轉變為經典型。這項結果顯示,MYC可能參與維持癌細胞的惡性特徵,也讓研究人員有機會進一步探索,能否透過干預相關機制改變癌細胞的行為。
研究也發現免疫相關線索 治療效果仍待驗證
除了MYC,研究團隊也觀察到與免疫調節有關的TIGIT蛋白質。這項發現提供另一條研究方向,有助了解胰臟癌細胞與人體免疫系統之間的互動,以及部分癌細胞如何避開免疫攻擊。
研究涉及的MYC與TIGIT相關機制,可能為未來治療策略提供線索,但細胞型態改變不等於腫瘤縮小,也不代表患者病情會因此改善。這項研究的結果仍須透過後續研究確認,才能判斷相關發現是否能發展成有效的胰臟癌療法。

The International Organization for Standardization's Technical Committee on Traditional Medicine (ISO/TC249) has issued a total of 149 international standards for traditional Chinese medicine, and another 69 are under development.

Research by Chen Yanjin, associate professor of the Department of Nursing at National Sun Yat-sen University, pointed out that nearly 40% of patients with moderate to severe obstructive sleep apnea give up treatment when using positive pressure respirators. The main reason for "suffocation" is highly related to psychological anxiety and fear. The results have been published in international journals.

Director of Disease Control and Prevention Luo Yijun pointed out that this year's "Health Coin" policy has successfully driven an upsurge in publicly funded influenza and COVID-19 vaccinations, reaching a six-year high, and the pneumococcal vaccination rate among the elderly has reached the target two months ahead of schedule. In the second phase, vaccination will be open to adults over 50 years old on November 2.
