長庚科技大學嘉義分部護理系基礎醫學組郭星君老師,今年獲頒本校學術作品發表績優獎的研究教師,也獲本年度(107)產學合作計畫減授授課時數獎勵。

郭老師實驗室,運用高通量蛋白質質譜基礎生物技術,大規模分析長庚臨床樣本(大腸癌1、肝膽胃2,3、牙周病4、兒科川崎氏症(KD)5 ),並且經分子生物的基因調控分析其生物標幟(biomarker)之功能性,讓以往疾病研究上的分子致病機轉的成果,可能運用於臨床治療。郭老師自2006年取得生化博士學位後,2006-2008(96/3 ~ 97/7)歷經國家衛生研究院博士後研究、高雄長庚醫院臨床基因體暨蛋白質核心實驗室擔任博士研究員。郭星君老師研究室:功能性蛋白質體研究室成員有6位專任碩士級研究助理與1位碩士生。開發天然物萃取物,提供輔助治療的可能,得以連結轉譯醫學;目前進行研究,當中尤以致癌機轉最能引起最大之興趣。在臨床上觀察到腫瘤的轉移及預後的多變性,因此對於腫瘤轉移機制及其輔助治療有相當的興趣。而郭老師的產學計劃與葡萄王生技公司開發天然萃取物將提供輔助治療的可能。

    產學計劃乃協助開發猴頭菌菌絲體發酵技術;利用 Hericium erinaceus 菌絲體發酵物,再目前經由HPLC定性定量分析有效成分猴頭素A,與 NMR 分析出結構,該發酵製程可以得到在每公斤猴頭菇類菌絲體凍乾 (Hericium erinaceus wet mycelium),活性成分猴頭素(Erinacine A, PubChem CID: 9867477)約 3-5 g6,在每公斤猴頭菇菌絲體凍乾品(Hericium erinaceus wet mycelium)進一步今年提的計劃案在去年的基礎上,純化原創猴頭菇類菌絲體活性產物猴頭素 S (Erinacine S, PubChem CID: 127047879),猴頭素 C (Erinacine C, PubChem CID: 15235994) 這製程再經由 HPLC 定性定量分析, NMR 分析出結構,可以得到活性成分約 2.0-3.0 g;準備進行探討嶄新天然物猴頭素 S (Erinacine S)抑制人類胃腸癌細胞轉移侵襲與表觀遺傳調控所扮演之角色的相關性機制研究。

    目前幾個研究單位發表關於猴頭菇子實體萃取成分抗肝癌、抗星狀細胞瘤、抗胃癌、抗血癌;然而郭老師針對猴頭菇菌絲體酒精萃取之活性成分猴頭素,抗大腸癌、抗胃癌機制仍不甚清楚。而針對開發的猴頭菇類菌絲體活性產物,進行抗癌之功能性開發,預防或減少大腸直腸癌、胃癌的傷害的產品,可望進一步拓展菇類保健產品升7,8,9。此外,郭老師開發猴頭菌菌絲體保護腦神經細胞發炎所扮演的角色相關性,在缺血再灌流傷害損傷、巴金森氏症治療機制的健康產品提供理論基礎10
