Exploring the protective role of caffeine against Taraxacum-Induced ribotoxic stress mediated through autophagy and mitochondrial depolarization.

ABSTRACT: The ribotoxic stress response is a pathway that gets activated when ribosomes get impaired, leading to disruptions in protein synthesis, increased inflammatory signaling, and cell death if left unresolved. Taraxacum can induce apoptosis-associated ribosomal RNA (rRNA) cleavage, however, the exact working mechanism of Taraxacum-induced rRNA cleavage remains unclear. In this study, we used the RNA integrity (RIN) value and 28S/18S ratio to confirm the integrity of experiments. Our RNA sequencing data showed that Taraxacum formosanum (T. formosanum) upregulated 893 genes and downregulated 509 genes and triggered hallmark genes of spliceosomes, TNF-α signaling via NF-κB, inflammatory response, and IL6-JAK-STAT3 signaling. Additionally, T. formosanum imbalanced the levels of ribosomal proteins
