Objective To investigate the protective effect of berberine (BBR) against ionizing radiation injury in rats and its mechanism of action. Methods Sprague-Dawley rats were divided into seven groups: normal control group, 1-Gy radiation group, 1-Gy radiation plus low-dose BBR (50 mg/kg) group, 1-Gy radiation plus high-dose BBR (150 mg/kg) group, 3-Gy radiation group, 3-Gy radiation plus low-dose BBR (50 mg/kg) group, and 3-Gy radiation plus high-dose BBR (150 mg/kg) group. All the groups except the normal control group were exposed to external irradiation with a medical electron linear accelerator, followed by BBR administration by gavage for consecutive ten days. The serum levels of superoxide dismutase (SOD), reduced glutathione (GSH), and malondialdehyde (MDA) were measured by using the micromethod. The pathological changes of the bone marrow and small intestine were observed with HE staining. Results Compared with the normal control group, the radiation groups showed significantly increased MDA levels (P < 0.05), significantly decreased SOD and GSH levels (P < 0.05), and more severe pathological damage of the bone marrow and small intestine. Compared with the radiation groups, the BBR groups showed significantly decreased MDA levels (P < 0.05), significantly increased SOD and GSH levels (P < 0.05), and reduced pathological damage to the bone marrow and small intestine, which were more marked in the high-dose BBR group. Conclusion BBR has a certain protective effect against radiation injury in rats, which may be through increasing the activity of antioxidant substances, enhancing free radical clearance, and thereby alleviating free radicals-caused oxidative damage.

Copy number variations (CNVs), which can affect the role of long non-coding RNAs (lncRNAs), are important genetic changes seen in some malignant tumors. We analyzed lncRNAs with CNV to explore the relationship between lncRNAs and prognosis in bladder cancer (BLCA). Messenger RNA (mRNA) expression levels, DNA methylation, and DNA copy number data of 408 BLCA patients were subjected to integrative bioinformatics analysis. Cluster analysis was performed to obtain different subtypes and differently expressed lncRNAs and coding genes. Weighted gene co-expression network analysis (WGCNA) was performed to identify the co-expression gene and lncRNA modules. CNV-associated lncRNA data and their influence on cancer prognosis were assessed with Kaplan-Meier survival curve. Multi-omics integration analysis revealed five prognostic lncRNAs with CNV, namely

The olfactory bulb (OB) is the first relay station in the olfactory system. In the OB, mitral/tufted cells (M/Ts), which are the main output neurons, play important roles in the processing and representation of odor information. Recent studies focusing on the function of M/Ts at the single-cell level in awake behaving mice have demonstrated that odor-evoked firing of single M/Ts displays transient/long-term plasticity during learning. Here, we tested whether the neural activity of M/Ts and sniffing patterns are dependent on anticipation and reward in awake behaving mice. We used an odor discrimination task combined with in vivo electrophysiological recordings in awake, head-fixed mice, and found that, while learning induced plasticity of spikes and beta oscillations during odor sampling, we also found plasticity of spikes, beta oscillation, sniffing pattern, and coherence between sniffing and theta oscillations during the periods of anticipation and/or reward. These results indicate that the activity of M/Ts plays important roles not only in odor representation but also in salience-related events such as anticipation and reward.

This study was aimed to design the first dual-target small-molecule inhibitor co-targeting poly (ADP-ribose) polymerase-1 (PARP1) and bromodomain containing protein 4 (BRD4), which had important cross relation in the global network of breast cancer, reflecting the synthetic lethal effect. A series of new BRD4 and PARP1 dual-target inhibitors were discovered and synthesized by fragment-based combinatorial screening and activity assays that together led to the chemical optimization. Among these compounds, 19d was selected and exhibited micromole enzymatic potencies against BRD4 and PARP1, respectively. Compound 19d was further shown to efficiently modulate the expression of BRD4 and PARP1. Subsequently, compound 19d was found to induce breast cancer cell apoptosis and stimulate cell cycle arrest at G1 phase. Following pharmacokinetic studies, compound 19d showed its antitumor activity in breast cancer susceptibility gene 1/2 (BRCA1/2) wild-type MDA-MB-468 and MCF-7 xenograft models without apparent toxicity and loss of body weight. These results together demonstrated that a highly potent dual-targeted inhibitor was successfully synthesized and indicated that co-targeting of BRD4 and PARP1 based on the concept of synthetic lethality would be a promising therapeutic strategy for breast cancer.
