まとめ
アロラキナーゼA阻害剤であるアリセルチブは,ドクソルビシンによる肝損傷およびマウスの線維症を予防します. 化学療法による副作用を軽減する 戦略を提示しています
科学分野:
- 薬理学について
- ヘパトロジー
- 腫瘍学
背景:
- ドキソルビシン (DOXO) は強力な抗がん剤ですが,投与量を制限する肝毒性および肝繊維症を引き起こす.
- オーロラキナーゼA (AURKA) はがんの進行と薬剤耐性に関与しています.
- DOXOによる肝損傷に対するAURKAの保護的役割は未調査のままである.
研究 の 目的:
- マウスモデルでDOXO誘発性肝毒性に対するAURKA阻害剤アリサーチブの保護効果を調査する.
- アリサーチブの潜在的保護作用の分子メカニズムを解明する.
主な方法:
- マウスは5日間毎日アリサーチブ (10 mg/ kg) を投与し,2日目はDOXO (20 mg/ kg) を投与した.
- 肝機能障害のバイオマーカー,酸化ストレス,炎症マーカー (IL-17A,NF-κB,STAT3),ERストレス (PERK),低酸素関連因子 (HIF-1α,VEGF-A),および線維症マーカー (TGF-β1,α-SMA) を評価した.
- 肝臓内炎症と線維症を評価した.
主要な成果:
- ALISERTIBは,DOXOによる肝機能障害と酸化ストレスを有意に減少させました.
- これはDOXO誘発のIL- 17A,NF- kB,STAT3,HIF- 1α,VEGF- A,PERKの活性化を抑制した.
- アリセルチブはDOXO誘発のTGF-β1およびα-SMA過剰発現を抑制し,肝繊維症と炎症を緩和した.
結論:
- アリサーチブはDOXO誘発の肝毒性および肝繊維症をマウスで軽減する.
- 保護メカニズムは,IL-17A/NF-κBとIL-17A/STAT3/HIF-1α/VEGF-Aのシグナル伝達経路を標的とする.
- アリサーチブは酸化ストレス,炎症,ERストレス,および線維症を緩和し,治療の可能性を示唆しています.

T Cell Types and Functions
1.4K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Targeted Cancer Therapies
7.8K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

PI3K/mTOR/AKT Signaling Pathway
3.9K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

Drugs that Stabilize Microtubules
2.1K
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
230
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...
