Akhir-akhir ini, perhatian telah diberikan untuk meneliti bahan alam laut yang berpotensi sebagai antikanker khususnya untuk kanker payudara, yaitu teripang atau sea cucumber. Triterpen glikosida merupakan senyawa bioaktif yang menunjukkan aktivitas antikanker atau aktivitas sitotoksik yang jumlahnya paling banyak terkandung dalam Teripang, seperti frondoside A, okhotosid B1-B3, intercedenside A-C, holothurin A, dan 24-dehydroechinoside. Pada penelitian ini, dilakukan penambatan molekul pada senyawa bioaktif teripang terhadap target reseptor ER-α, FGFR1, VEGFR2, PR, dan IGF-1R yang berperan dalam penyakit kanker payudara untuk diamati interaksi yang situs aktifnya mempunyai potensial sebagai antikanker payudara. Dari hasil penambatan hanya ER-α dan IGF-1R yang menunjukkan hasil energi bebas ikatan paling rendah dengan menggunakan parameter Vina. Dari hasil penambatan dan visualisasi interaksi senyawa bioaktif teripang dengan ER- α, senyawa 24-dehidroechinoside, holothurin A, intercedenside A, intercedenside B, okhotoside B1, dan okhotoside B2 memiliki kemiripan posing dengan kontrol positif (inhibitor). Adapun pada IGF-1R hanya senyawa 24-dehidroechinoside yang ditemukan memiliki kemiripan posing dengan kontrol positif. ...... Recently, attention has been given to examine the potential of marine natural products as anticancer, especially for breast cancer, which is Teripang or sea cucumber. Triterpene glycosides are bioactive compounds mostly found in sea cucumber that show anticancer activity or citotoxic activity, such as frondoside A, okhotosides B1-B3, intercedensides A-C, holothurin A, and 24- dehydroechinoside. Molecular docking of sea cucumber bioactive compounds was conducted towards five receptor target which have role in breast cancer, such as estrogen receptor alpha, fibroblast growth factor receptor 1 (FGFR1), vascular endothelial growth factor receptor 2 (VEGFR2), progesterone receptor (PR), insulin-like growth factor 1 receptor (IGFR1) to observed the interaction which active site has the potential as anti-breast cancer. The results shows that ER-α and IGF-1R gives the lowest binding energy by using Vina parameter. Compounds that showed similar posing of positive control (inhibitor) in ER- α are 24-dehidroechinoside, holothurin A, intercedenside A, intercedenside B, okhotoside B1, and okhotoside B2. While in IGF-1R, 24-dehidroechinoside is the only compound who showed similar posing to the positive control.

Abstrak :
Leading authorities on percutaneous tumor ablation come together in this volume to provide a complete overview of everything physicians and other health professionals need to know to successfully implement and administer an image-guided ablation service. After an introduction to the protocols and attendant physics of ablation technology, concise organ-based chapters focus on a wide range of both straightforward and atypical cases to teach readers how to handle the unique clinical and technical challenges associated with percutaneous tumor ablation in different areas of the body. Succinct, step-by-step descriptions complement high-resolution images throughout to illustrate the nuances of each procedure. This must-have clinical reference will develop the technical and clinical tumor ablation skills of every fellow and practicing physician in interventional radiology, oncology, and surgical oncology.
