    Personalized Biomedicine in Cancer: From Traditional Therapy To Sustainable Healthcare
    (Elsevier, 2020) Ulu,G.T.; Kiraz,Y.; Baran,Y.
    What images are coming to your mind when you think about sustainable and qualified life? The main picture drawn is healthcare. Many people suffer from cancer; more than 18.1 million people were diagnosed with cancer and 9.6 million people died from cancer worldwide in 2018. Therefore many diagnosis and treatment strategies that are shaped and regulated by biomedicine approaches have been developed to solve this problem. Biomedicine is an interdisciplinary science to understand the interaction of biological, chemical, and physiological principles. These principles should be brought together to be applicable and sustainable for qualified life. Drug discovery and combination therapy using nanocarriers and natural compounds are being innovated as new approaches and opportunities for cancer treatment. Theoretically and practically, there is no limit to the development of new biomedicinal tools for personalized medicine in cancer. Therefore personalized medicine plays an important role for reaching successful therapy with low cost. By discovering the diverse potential of biomedicine, we can provide better healthcare in the world. © 2020 Elsevier Inc. All rights reserved.

    A New Drug Testing Platform Based on 3d Tri-Culture in Lab-On Devices
    (Elsevier, 2020) Gökçe, Begüm; Akçok, İsmail; Çağır, Ali; Pesen Okvur, Devrim
    Drug discovery has a 90% rate of failure because preclinical platforms for drug testing do not mimic the in vivo conditions. Doxorubicin (DOX) is a commonly used drug to treat breast cancer patients even though it has side effects. Lab-on-a-chip (LOC) devices provide spatial control at the micrometer scale and can thus emulate the cancer microenvironment. Here, using a multidisciplinary approach, a new drug testing platform based on 3D tri-culture in LOC devices was developed. Breast cancer cells alone or with normal mammary epithelial cells and macrophages were cultured in matrigel in LOC devices. The platform was used to test DOX and (R)-4'-methylklavuzon (KLA), which is a new anti-cancer drug candidate. Results showed that DOX and KLA were equally effective on breast cancer cells in 3D monoculture. KLA produced 26% less death for breast cancer cells than DOX in 3D tri-culture. More importantly, DOX was not selective between breast cancer cells and normal mammary epithelial cells in 3D tri- culture whereas KLA caused 56% less cell death than DOX for normal mammary epithelial cells. Results strongly recommend that 3D tri-culture in LOC devices be used for assessment of drug toxicity at the preclinical stage.
