Non-canonical dihydrolipoyl transacetylase promotes chemotherapy resistance via mitochondrial tetrahydrofolate signaling.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Chemotherapy is often a primary treatment for cancer. However, resistance leads to therapeutic failure. Acetylation dynamics play important regulatory roles in cancer cells, but the mechanisms by which acetylation mediates therapy resistance remain poorly understood. Here, using acetylome-focused RNA interference (RNAi) screening, we find that acetylation induced by mitochondrial dihydrolipoyl transacetylase (DLAT), independent of the pyruvate dehydrogenase complex, is pivotal in promoting resistance to chemotherapeutics, such as cisplatin. Mechanistically, DLAT acetylates methylenetetrahydrofolate dehydrogenase 2 (MTHFD2) at lysine 44 and promotes 10-formyl-tetrahydrofolate (10-formyl-THF) and consequent mitochondrially encoded cytochrome c oxidase II (MT-CO2) induction. DLAT signaling is elevated in cancer patients refractory to chemotherapy or chemoimmunotherapy. A decoy peptide DMp39, designed to target DLAT signaling, effectively sensitizes cancer cells to cisplatin in patient-derived xenograft models. Collectively, our study reveals the crucial role of DLAT in shaping chemotherapy resistance, which involves an interplay between acetylation signaling and metabolic reprogramming, and offers a unique decoy peptide technology to overcome chemotherapy resistance.
