Hira, 2024, review article Abstract: Lactate and ATP formation by aerobic glycolysis, the Warburg effect, is considered a hallmark of cancer. During angiogenesis in non-cancerous tissue, proliferating stalk endothelial cells (ECs) also produce lactate and ATP by aerobic glycolysis. In fact, all proliferating cells, both non-cancer and cancer cells, need lactate for the biosynthesis of building blocks for cell growth and tissue expansion. Moreover, both non-proliferating cancer stem cells in tumors and leader tip ECs during angiogenesis rely on glycolysis for pyruvate production, which is used for ATP synthesis in mitochondria through oxidative phosphorylation (OXPHOS). Therefore, aerobic glycolysis is not a specific hallmark of cancer but rather a hallmark of proliferating cells and limits its utility in cancer therapy. However, local treatment of angiogenic eye conditions with inhibitors of glycolysis may be a safe therapeutic option that warrants experimental investigation. Most types of cells in the eye such as photoreceptors and pericytes use OXPHOS for ATP production, whereas proliferating angiogenic stalk ECs rely on glycolysis for lactate and ATP production.

4. Odpornost glioblastoma na radioterapijo : vpliv rakavih matičnih celic in mikroo[ko]lja tumorjaBarbara Breznik, Bernarda Majc, Anamarija Habič, Urška Ušeničnik, Andrej Porčnik, Roman Bošnjak, Jernej Mlakar, Marija Skoblar Vidmar, Tanja Jesenko, Maja Čemažar, Tamara Lah Turnšek, Metka Novak, 2022, published scientific conference contribution (invited lecture) Abstract: Glioblastom je najpogostejši možganski tumor pri odraslih z zelo slabo prognozo preživetja bolnikov. Ta je posledica odpornosti glioblastoma na standardno zdravljenje, ki vključuje radioterapijo in kemoterapijo. Z namenom načrtovanja učinkovitejših pristopov zdravljenja preučujemo biološke mehanizme odpornosti glioblastoma na radioterapijo s poudarkom na mikrookolju tumorja in rakavih matičnih celicah. V predkliničnih raziskavah uporabljamo napredne in personalizirane celične modele, ki posnemajo mikrookolje tumorja v bolnikih in z večjo natančnostjo napovedo odziv bolnika na zdravljenje. Hkrati so takšni modeli pomembni za testiranje novih pristopov za zdravljenje kot je imunoterapija.
