MTAP

甲硫腺苷磷酸化酶(MTAP)是細胞代謝中的關鍵蛋白,也常被稱為MTAPase。它能分解代謝過程中產生的甲硫腺苷(MTA),轉化為腺嘌呤和甲硫基核糖-1-磷酸,這兩種產物可重新參與嘌呤與蛋氨酸的合成循環,維持細胞內代謝平衡,防止MTA積累損傷細胞。
MTAP基因缺失在膠質母細胞瘤、肺癌、黑色素瘤等多種癌癥中常見。這類腫瘤細胞因MTAP缺失,代謝模式發生改變,存在獨特的生存弱點——對PRMT5抑制劑更敏感。目前針對這一特性的藥物研發已有突破,多款PRMT5抑制劑(如GSK3326595)進入臨床試驗階段,用于治療MTAP缺失的晚期實體瘤,為這類患者提供了新的治療方向。

CSB-RA299565A0HU

Immunofluorescence staining of Hela cell with CSB-RA299565A0HU at 1:50, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

CSB-RA299565A0HU

Overlay Peak curve showing Hela cells stained with CSB-RA299565A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 35min at 4℃.Control antibody (green line) was Rabbit IgG (1ug/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
