Final report

 
Results in Hungarian
2020. szeptember 1. és 2024. augusztus 31. között tíz lektorált közleményt publikáltunk az OTKA NKFI K 135027 pályázat anyagi támogatásából. Ezek közül D1-kategóriás folyóiratban (Scimago) jelent meg öt publikáció, melyeknél a vezető kutató a levelező szerző, továbbá egy kézirat (melynél a vezető kutató a levelező szerző) Q1-kategóriás folyóiratban olvasható, illetve egy D1-kategóriás folyóiratban közölt munkában a vezető kutató társszerző. Eredményeink azt a hipotézist támasztják alá, hogy OXPHOS hiányában a tumorsejtek túlélését a glutaminolízis oxidatív dekarboxilációs ága tartja fenn. Különböző útvonalakat azonosítottunk, melyek NAD+-ot és kinont szolgáltatnak az útvonal működéséhez, míg azt a feltevést, hogy OXPHOS hiányában az MTHFD1L a fő ATP-termelő reakció, megcáfoltuk. Az RPPA analízisből származó eredményeink jelenleg elbírálás alatt vannak. Emellett a humán agy OXPHOS szempontjából kritikus enzimjeiről publikáltunk sejtspecifikus adatokat.
Results in English
Between September 1, 2020, and August 31, 2024, with financial support from the OTKA NKFI grant K 135027, we published ten peer-reviewed articles. Of these, five are in D1-category journals (Scimago) with the PI as the corresponding author, one in a D1-category journal with the PI as co-corresponding author, one in a Q1-category journal (with the PI as corresponding author), and one in a D1-category journal with the PI as a co-author. Our findings bolster the hypothesis that the oxidative decarboxylation branch of glutaminolysis, in the absence of OXPHOS, sustains cancer cell viability. We identified pathways for NAD+ and quinone provision, while rejecting the concept of ATP provision via MTHFD1L as a major pathway in the absence of OXPHOS. Results from the RPPA analysis are currently under revision or review. Additionally, data on human brain OXPHOS-critical enzymes in a cell-specific manner, have been published.
