高选择性PI3Kγ抑制剂ZX-4081为全球第二个进入临床的同类产品，主要针对实体瘤，其相同药物IPI-549与PD1/PDL1联合用药，已在三阴性乳腺癌、尿路上皮癌等实体瘤中显现出明显的效果。与此同时，征祥医药在抗感染方向布局了重磅管线ZX-7101A，定位于新一代抗流感药物，整个疗程只需要服用一次，同时还可以预防流感。...
PI3K/AKT pathwayT cellsCANCER cellsBREAST cancerIntroduction: This study probes the mechanism of the PARP9/PI3K/AKT/PDL1 axis in the chemoresistance and immune escape of breast cancer cells. Material and methods: The expression of related genes was detected in MCF-7/FUL cells....
PI3K/AKT/mTOR通路激活可见于各大肿瘤,常见于妇科肿瘤。目前的靶向药主要有三大类,即靶向PI3K/mTOR、广谱型的PI3K抑制剂和选择性的PI3K抑制剂。前不久,首个PI3K抑制剂获批于乳腺癌,开启历史性一刻。 1.Alpelisib获得FDA批准,治疗PI3K突变乳腺癌可延长一倍的PFS 2019年5月24日,FDA批准了诺华公司的PI3k抑制剂alpelisib...
IFNb-induced PI3K/Akt regulates neuronal FoxA1 and PDL1. It is known that JAK (Janus kinase) and a STAT (signal trans- ducer and activator of transcription) pathway is activated by IFNs; however, the importance of many other pathways in IFN-mediated signalling is also established16–20. ...
PDK1 indirectly enhanced mTORC2 activity. Activated AKT phosphorylates the most critical downstream effector, mTOR complex 1 (mTORC1), which promotes cell proliferation and oncogenic transformation [18]. AKT has three isoforms: AKT1/2/3. AKT gene amplification (common in AKT1) is more prevalent in...
可以对残留肿瘤中浸润的巨噬细胞进行重编程,除了pi3kγ抑制剂自身的抗肿瘤效果外,其 更能促进抗pd-1介导的肿瘤消退,增强射频消融残留肿瘤抗pd-1治疗的敏感性,克服现有 技术中射频消融残留肿瘤耐药性。进一步地,提供有pi3kγ抑制剂和抗pd-1联合治疗irfa 后残留肿瘤的治疗策略,pi3kγ/akt通路的阻断可增强pd-1阻断...
I类PI3K(例如, p110α、 p110β、 p110γ和p110δ通常由酪氨酸激酶或G‑蛋白偶联受体活化以产生PIP3, PIP3结合下游介质, 如Akt/PDK1途径中的那些、 mTOR、 Tec家族激酶和Rho家族GTP酶。II类PI3K(例如, PI3K‑C2α、PI3K‑C2β、PI3K‑C2γ)和III类PI3K(例如, Vps34)通过合成PI(3)P和PI(3,4)...

进一步地,提供有PI3Kγ抑制剂和抗PD-1联合治疗IRFA后残留肿瘤的治疗策略,PI3Kγ/AKT通路的阻断可增强PD-1阻断剂的抗肿瘤活性,抑制恶性生长,并提高IRFA后模型的存活率,相比于PD-1阻断剂或PI3Kγ抑制剂单独应用而言,联合使用效果更为显著。通过本发明提供的PI3Kγ抑制剂、协同PD-1阻断剂治疗策略,能为临床IRFA后...
Table S2. A literature search revealed that phosphoinositide-3-kinase–protein kinase B (PI3K/AKT), HIF-1, FoxO, JAK/STAT, chemical carcinogenesis receptor activation, endocrine resistance, and PD1/PDL1-related pathways may play an important role in BCCD. In addition, the target gene–signaling...
