分子生物学分子生物学
生物化学生物化学

背景情况:

神经母细胞瘤 (NB) 是一种儿童癌症,以其侵略性和常见的化学抗药性发展而闻名.
铁死是一种受调节的细胞死亡形式,在NB中具有潜在的治疗脆弱性,但其与化疗和化疗抵抗的相互作用仍然不清楚.

研究的目的:

为了研究铁死在抗化学性神经母细胞瘤中的作用.
探索结合诱导铁亡的药物与治疗NB的标准化疗的潜力.

主要方法:

在NB细胞系和患者衍生异种移植模型中使用各种作用机制 (MOA) 诱导铁亡.
评估结合标准化疗治疗的铁灭症诱导.
在耐化学物质的NB模型中评估一种涉及化疗和铁素减少酶抑制剂Auranofin的组合疗法.

主要成果:

主要的抗氧化途径在耐火性NB中被上调,这表明可以诱导铁亡.
标准化疗可以干扰某些诱导铁亡的机制,特别是那些针对GPX4.4的机制.
奥拉诺芬和化疗的结合抵消了化疗的抗ferroptotic作用,显著改善了耐化学药性NB异种移植的存活率.

Targeted Cancer Therapies

Targeted Cancer Therapies

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.
There are several types of targeted therapies against...

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Treatment Resistant Cancers

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
