Advanced Science, EarlyView.PFOA exposure induces pregnancy loss by promoting glutaminolysis, which further causes ammonia accumulation in macrophages. Cellular ammonia retention results in damage to mitochondria and lysosomes, which leads to cell death eventually. Impaired lysosomes also decrease the secretion of the Cathepsin B (CTSB), and attenuate macrophage infiltration and ...

Epstein‐Barr Virus Expressed Long Non‐Coding RNA (lncBARTs) Regulate EBV Latent Genome Replication
Advanced Science, EarlyView.EBV produces abundant level of lncBARTs, which are essential for maintaining viral genome replication in EBV‐associated cancers. LncBARTs interact with a complex comprising BRD4, CTCF and viral protein EBNA1 at EBV oriP region. This interaction tethers oriP to host chromosomes, facilitating EBV episome replication.
