Bim, Bad, and Bax: a deadly combination in epileptic seizures.
نویسندگان
چکیده
Several Bcl-2 family members, including Bim, may contribute to programmed cell death by inducing mitochondrial cytochrome c release, which activates caspase-9 and then caspase-3, the "executioner" of the cell. In this issue of the JCI, Shinoda and collaborators show the key role of Bim in epileptic seizure-induced neuronal injury and identify the contribution of transcription factors responsible for seizure-induced Bim upregulation.

BH3-only proteins that bind pro-survival Bcl-2 family members fail to induce apoptosis in the absence of Bax and Bak.
The BH3-only proteins Bim and Bad bind to the antiapoptotic Bcl-2 proteins and induce apoptosis in wild-type cells and cells from either bax(-/-) or bak(-/-) animals. In contrast, constitutively active forms of Bim and Bad failed to induce apoptosis in bax(-/-)bak(-/-) cells. Expression of Bax restored susceptibility of the cells to Bim and Bad. In addition, Bax but not Bim or Bad sensitized th...
متن کاملRuxolitinib synergizes with DMF to kill via BIM+BAD-induced mitochondrial dysfunction and via reduced SOD2/TRX expression and ROS
We determined whether the myelofibrosis drug ruxolitinib, an inhibitor of Janus kinases 1/2 (JAK1 and JAK2), could interact with the multiple sclerosis drug dimethyl-fumarate (DMF) to kill tumor cells; studies used the in vivo active form of the drug, mono-methyl fumarate (MMF). Ruxolitinib interacted with MMF to kill brain, breast, lung and ovarian cancer cells, and enhanced the lethality of s...
متن کاملThe BH3 alpha-helical mimic BH3-M6 disrupts Bcl-X(L), Bcl-2, and MCL-1 protein-protein interactions with Bax, Bak, Bad, or Bim and induces apoptosis in a Bax- and Bim-dependent manner.
A critical hallmark of cancer cell survival is evasion of apoptosis. This is commonly due to overexpression of anti-apoptotic proteins such as Bcl-2, Bcl-X(L), and Mcl-1, which bind to the BH3 α-helical domain of pro-apoptotic proteins such as Bax, Bak, Bad, and Bim, and inhibit their function. We designed a BH3 α-helical mimetic BH3-M6 that binds to Bcl-X(L) and Mcl-1 and prevents their bindin...
متن کاملبررسی تاثیر هسپرتین بر سه فاکتور پیش آپوپتوزی Bad، Bak، و Bim در محیط شبیه سازی شده
مقدمه: بسیاری از ترکیبات مشتق شده از گیاهان دارویی مانند آنتی‌اکسیدان‌ها و پلی فنل ها نقش بسزایی در پیشگیری و درمان انواع سرطان ها دارند. یکی از فرایندهای مهار سرطان، فعال کردن مسیر آپوپتوز است و ما قصد داریم در این مطالعه، تأثیر دینامیک مولکولی هسپرتین (Hesperetin) را بر روی فاکتورهای پیش آپوپتوزی Bad، Bak و Bim در محیط شبیه‌سازی‌شده بررسی نماییم. روش کار: اطلاعات مربوط به ساختار سه بعدی و فای...
