DOLPHIN AI 發現數百個隱形癌症標記

麥基爾大學的研究人員研發出一款名為 DOLPHIN 的人工智能工具,能夠在單一細胞內揭露以往難以察覺的疾病標記。這項突破不僅有助醫生更早期檢測疾病,還能精準配對最合適的治療方案。

深入細胞基因組件,揭示疾病秘密

疾病標記通常是 RNA 表達上的微妙變化,能夠提示疾病是否存在、病情嚴重程度及對治療的反應。傳統基因層級的分析方法,只將這些標記簡化為每個基因的總數,掩蓋了關鍵的變異,猶如冰山一角。

DOLPHIN 利用人工智能技術,突破基因層級限制,細看基因如何由稱為外顯子(exons)的細小片段組合而成,從而更清楚地描繪細胞狀態。正如麥基爾大學博士生宋凱祿所言:「基因不是單一積木,而是由多個小積木組成的樂高套裝。透過觀察這些積木如何銜接,我們的工具能揭示長期被忽略的重要疾病標記。」

在一項胰臟癌患者的單細胞數據分析中,DOLPHIN 發現逾 800 個傳統工具未能辨識的疾病標記,並成功區分出高風險的侵襲性癌症患者與病情較輕者,為醫生選擇適切治療方案提供關鍵資訊。

邁向「虛擬細胞」的未來

這項突破為建立人類細胞的數碼模型奠定基礎。DOLPHIN 能產生比傳統方法更豐富的單細胞輪廓,使研究人員可在實驗室或臨床試驗前,模擬細胞行為及藥物反應,節省大量時間與資源。下一階段,研究團隊計劃將工具的應用範圍從少量數據擴展至數百萬細胞,為未來更精確的虛擬細胞模型鋪路。

研究背景

這項研究由麥基爾大學醫學系助理教授、麥基爾大學健康中心研究所初級科學家丁俊領導,相關成果已發表於《Nature Communications》。研究獲得呼吸研究梅金斯-克里斯蒂席位、加拿大健康研究院、加拿大自然科學與工程研究理事會及魁北克研究基金會支持。

評論與啟示

DOLPHIN 的誕生標誌著單細胞生物學研究進入一個全新層次。過去基因層級的分析往往將複雜的細胞內部結構簡化成「黑盒」,忽略了基因拼接和外顯子變異帶來的細節,這些細節正是揭示疾病早期徵兆的關鍵。DOLPHIN 以人工智能技術深入解構基因拼接,猶如為細胞解剖出更精細的地圖,這不僅提升了早期癌症篩查的準確度,更有助於個人化醫療的精準匹配。

更重要的是,這項技術為虛擬細胞模型的建立開啟了大門。未來,醫學研究或可在電腦中模擬病理狀態和藥物反應,大幅縮短藥物研發週期及降低研發成本。這種「數碼雙胞胎」的概念,不但能加速臨床決策,還能減少動物實驗,符合倫理與效率的雙重需求。

然而,挑戰仍在於如何將這項技術推廣至龐大的細胞數據集,並確保模擬結果在臨床上的可靠性與普適性。此外,如何整合多種分子層面的數據(如蛋白質組學、代謝組學)以打造更全面的細胞模型,也是未來研究重點。

總括而言,DOLPHIN 不只是癌症標記檢測的突破,更是精準醫療與數字生物學的里程碑。對香港及全球醫療界而言,這種以 AI 助力的單細胞解析技術將成為未來疾病診斷和治療的核心利器,帶來更早期、更個人化、也更有效的醫療方案。

Create a hyper-realistic promo image using my uploaded photo.  
Keep my real face exactly as it is (no changes to eyes, mouth, jawline, or skin).  
Place my portrait seamlessly inside the design of the US 100-dollar bill, maintaining the texture and engraving lines.  
Add two more versions:  
- One on the Euro (€100) banknote  
- One on the British Pound (£50) banknote  
Ensure the portrait blends naturally with the currency engraving style, with deep shadows, embossed effect, and authentic banknote detailing.  
Ultra HD, crisp details, cinematic lighting, clean background, premium quality Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel, true-to-life portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference). Create a portrait of a  fair-skinned woman with long, curly dark hair styled in a high ponytail, her head turned to the side, her expression neutral and serene; her makeup features defined eyebrows, subtle eyeliner, light blush, and glossy lips; she wears dangling earrings with a floral design; she has a piercing in her ear; the image is in ultra-high 8K resolution, showcasing detailed skin textures, crisp edges, and sharp focus on her eyes; a medium shot, taken from the side to emphasize her profile, with a shallow depth of field that softly blurs the background; soft, diffused lighting illuminates her face evenly, creating subtle shadows and highlights, with a warm color palette of soft browns and creams; she is wearing a dark strapless top; the background is a soft, neutral tone, ensuring the focus remains on the subject; no additional props are present; photorealistic style, akin to a raw camera capture, is achieved using an 85mm lens, ISO 100, and an aperture of f/2.0 for a shallow depth of field and soft background blur.

A young woman with fair skin is taking a selfie inside a fitness center (gym).

Main Subject: A young woman with long black hair in a messy bun. She is wearing a light cream or ivory long-sleeved sports zipper jacket and black tight sports shorts. She is also wearing long white socks with black stripes at the top and white sports shoes.

Expression and Pose: She is sitting on a weight training machine (apparently a leg press machine or similar) and holding a phone (with a leopard/leopard print case) to take a selfie in the mirror or using the front camera, with her face forward, a soft smile, and her face and eyes looking at the mirror.

Background (Gym): The background is dominated by modern gym equipment in dark gray and red. There are a few other unfocused people in the background, including a man on the left lifting weights or standing near a barbell, and another man in a green shirt standing near equipment. The gym floor appears dark.

Brief Prompt (Suitable for Image Search or Hashtags):

Selfie in the gym, young woman with messy bun and cream jacket, sitting on a training machine, aesthetic sporty, indoor lighting. Without changing her face.
