N-methyladenosine (m6A) is the most prevalent chemical modification in eukaryotic mRNAs and plays key roles in diverse cellular processes. Precise localization of m6A sites is thus critical for characterizing the functional roles of m6A in various conditions and dissecting the mechanisms governing its deposition. Here, we design a combined framework of Transformer architecture and recurrent neural network, deepSRAMP, to identify m6A sites using sequence-based and genome-derived features.

The pathogenesis and immune mechanism of tuberculosis are not clear, and it is urgent to find new drugs, diagnosis, and treatment targets. A useful tool in the quest to reveal the enigmas related to infection and disease is the single-cell sequencing technique.
View Article and Find Full Text PDFTuberculosis, a contagious bacterial infection caused by Mycobacterium tuberculosis, is a substantial global health problem, impacting millions of lives annually. Exhausted T-cell signatures are critical for predicting clinical responses to tuberculosis infection. To obtain a panoramic transcriptional profile of T cells, we performed single-cell RNA-sequencing analysis of CD4 T and CD8 T cells isolated from peripheral blood mononuclear cells of healthy individuals and patients with tuberculosis.

In L-glutamic acid (L-Glu)-damaged HT22 cells, a 3-h pre-incubation with OST-enhanced cell viability suppressed the apoptosis rate; inhibited the activities of caspase-3, caspase-8, and caspase-9; reduced the over-accumulation of intracellular reactive oxygen species; restored the dissipated mitochondrial membrane potential; and regulated the expression levels of B cell lymphoma-2 (Bcl-2), Bax, cleaved poly (ADP-ribose) polymerase (PARP), NF-E2p45-related factor 2 (Nrf2), and its downstream proteins. In amyloid precursor protein/presenilin 1 (APP/PS1) transgenic mice, an 8-week OST administration improved the pathological behaviors related to memory and cognition, and reduced the expression levels of 4-hydroxynonenal, the deposition of β-amyloid peptides and neuronal fiber tangles formed by the high phosphor-Tau in the brain.
