在一项新的研究中,来自美国圣犹大儿童研究医院的研究人员开发出首个靶向GRP78的嵌合抗原受体(CAR)T细胞(CAR-T,下称GRP78 CAR-T)。他们的GRP78 CAR ...
GRP78 作为 ATF6α 的靶基因,在肿瘤转移中具有重要作用。 敲低 GRP78 可显著上调被 ATF6α 抑制的 ΔNp63α 的蛋白和 mRNA 水平,并抑制 ATF6α 介导的细胞迁移;而过表达 GRP78 则降低 ΔNp63α 表达,促进细胞迁移。 恢复 ΔNp63α 表达可逆转 GRP78 诱导的细胞迁移增加。
撰文丨王聪编辑丨王多鱼排版丨水成文结直肠癌(CRC)是第三常见的恶性肿瘤,也是癌症相关死亡的第二大原因。靶向 PD-1/PD-L1、CTLA-4 ...
这些作者确定GRP78为候选的AML抗原,因为它在AML癌细胞表面上表达,但在正常骨髓中不表达。GRP78存在于每个细胞的内质网中。在正常细胞中,GRP78在 ...
RESULTS GRP78与CotH3表达: MDMs感染6小时后GRP78表达上调1.3倍,16小时后达2.5倍;CotH3表达随时间延长显著增加。 糖尿病小鼠肾脏中CotH3表达较非糖尿病组高20倍,LAmB治疗可降低表达。 患者鼻窦组织中GRP78表达较正常组织高117倍,治疗后下降87%。 miRNAs调控: ...
通常情况下,GRP78驻留在细胞的内质网中。 但当细胞处于压力下时,伴侣蛋白会迁移到细胞核,在那里它会改变基因活性并改变细胞的行为,使癌 ...
These and other GRP78 inhibitors are now being tested as treatments for both COVID-19 and cancer. These drugs may also prove useful for treating future coronaviruses that depend on GRP78 for entry ...
Cripto and GRP78 cooperatively regulate activin/Nodal/TGF-β signaling To test the function of the cell surface Cripto/GRP78 complex, we generated NCCIT cell populations stably expressing shRNAs ...
We show here that anti-GRP78 autoantibodies upregulate TF and its PCA through a mechanism involving depletion of ER Ca2+ stores. This very effect on ER Ca2+ stores also caused activation of the ...
The researchers also found that a GRP78-targeting monoclonal antibody (humanized MAb159, hMAb159) could be used in lung epithelial cells, to deplete GRP78 and csACE2 from the cell surface.
