The mechanistic action of histone deacetylase 8 (HDAC8) in cancer motility, including epithelial-mesenchymal transition (EMT), remains largely undefined. We found that the expression of HDAC8 was upregulated in breast cancer (BC) cells and tissues as compared to the controls. Further, BC tissues had the highest values of HDAC8 expression among 31 kinds of cancers.

Studies on biological functions of N-methyladenosine (mA) modification in mRNA have sprung up in recent years. We find mA can positively regulate the glycolysis of cancer cells. Specifically, mA-sequencing and functional studies confirm that pyruvate dehydrogenase kinase 4 (PDK4) is involved in mA regulated glycolysis and ATP generation.

Studies on biological functions of N6-methyladenosine (m6A) modification in mRNA have drawn significant attention in recent years. Here we describe the construction and characterization of a CRISPR-Cas13b-based tool for targeted demethylation of specific mRNA. A fusion protein, named dm6ACRISPR, was created by linking a catalytically inactive Type VI-B Cas13 enzyme from Prevotella sp.

N6-methyladenosine (mA) is the most abundant modification on eukaryotic mRNA, which regulates all steps of the mRNA life cycle. An increasing number of studies have shown that mA methylation plays essential roles in tumor development. However, the relationship between mA and the progression of cancers remains to be explored.

Background: Brain metastasis (BM) is one of the principal causes of mortality for lung cancer patients. While the molecular events that govern BM of lung cancer remain frustrating cloudy.

Methods: The miRNA expression profiles are checked in the paired human BM and primary lung cancer tissues.

Brain-derived neurotrophic factor (BDNF) is a master regulator of synaptic plasticity in various neural circuits of the mammalian central nervous system. Neuron activity-induced BDNF gene expression is regulated through the Ca/CREB pathway, but other regulatory factors may also be involved in controlling BDNF levels. We report here that Wnt/β-catenin signaling plays a key role in controlling neuron activity-regulated BDNF expression.

Mammalian target of rapamycin (mTOR) signaling plays a critical role in the regulation of activity-dependent protein synthesis in neurons. It is well established that the GTPase-activating protein tuberous sclerosis complex proteins (2TSC2) is an upstream inhibitor of mTOR. In this study, we show that glutamate stimulation down-regulates TSC2 protein in cortical cultures via NMDA receptor (NMDAR) activation.
