SRSF1
SRSF1,全稱為絲氨酸/精氨酸豐富剪接因子1,常用別名SR剪接因子1。它是細胞內RNA剪接調控蛋白,廣泛表達于人體各類組織,參與RNA剪切、加工及轉運調控,對基因表達調控、細胞增殖分化具有關鍵作用,維持細胞正常轉錄翻譯過程。 SRSF1異常高表達與多種惡性腫瘤密切相關,在肺癌、乳腺癌、白血病等腫瘤中顯著升高,能夠通過調控RNA剪接,促進腫瘤細胞增殖、侵襲轉移及耐藥,是腫瘤不良預后的潛在標志物。目前SRSF1抑制劑處于臨床前研究階段,通過抑制其RNA剪接調控功能,阻斷腫瘤惡性進展,為腫瘤提供新型治療思路。

IHC image of CSB-RA909596A0HU diluted at 1:100 and staining in paraffin-embedded human colorectal cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.

Overlay Peak curve showing SH-SY5Y cells stained with CSB-RA909596A0HU (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.
