Combination therapy is increasingly favored by pharmaceutical companies and researchers as an effective way to quickly discover new drugs with excellent efficacy, especially in the treatment of complex diseases. Previously, we successfully developed a computational screening method to identify such combinations, although it fell short in elucidating their synergistic mechanisms. In this work, we have transitioned to a highest single agent (HSA) synergy model for network screening, which streamlines the discovery of promising combinations and facilitates the investigation of their synergistic effects.

However, changes in the biomarkers of senescent cells have not been reported in detail in these animals. To lay a foundation for the use of doxorubicin-induced aging mice, we examined the biomarkers of hepatic and renal senescent cells in these mice.

We previously developed a potentially universal computational screening approach for combination drugs and used this approach to successfully identify some beneficial combinations for the treatment of heart failure. Herein, this screening approach was used to identify novel combination drugs for the treatment of epilepsy in an approved drug library.

Traditional combination drug discovery depends on large-scale high-throughput experimental approaches that are time-consuming and costly. Herein we developed a novel, rapid, and potentially universal computer-guided combination drug-network-screening approach based on a set of databases and web services that are easy for individuals to obtain and operate, and we discovered for the first time that the menthol-allethrin combination screened by this approach exhibited a significant synergistic cardioprotective effect .

To determine whether Akt2 expression is critical to MT prevention of DCM, mice with either global Akt2 gene deletion (Akt2-KO), or cardiomyocyte-specific overexpressing MT gene (MT-TG) or both combined (MT-TG/Akt2-KO) were used. Akt2-KO mice exhibited symptoms of DCM (cardiac remodelling and dysfunction), and reduced expression of glycogen and glucose metabolism-related proteins, despite an increase in total Akt (t-Akt) phosphorylation.

This study aimed to evaluate the cardiotoxicity of graphene oxide (GO) and reduced GO (rGO) and , as well as to investigate the underlying toxicity mechanisms.
Methods: GO was reduced by gamma irradiation to prepare rGO and then characterized by UV/visible light absorption spectroscopy.
Background: Coronavirus disease 2019 (COVID-19) is an ongoing global pandemic. The ability to predict cardiac injury and analyze lymphocyte immunity and inflammation of cardiac damage in patients with COVID-19 is limited. We aimed to determine the risk factors and predictive markers of cardiac injury in these patients.

Sulforaphane-rich broccoli sprout extract (BSE) and zinc can effectively induce Nrf2 and metallothionein, respectively, to protect against IH-induced cardiomyopathy via antioxidative stress. However, whether the cardiac protective effects of the combination of BSE and zinc can be synergistic or the same has not been evaluated.

Recently, a causative role for BRCA1/2 in cardiovascular diseases has been emerging. In this review, we summarize currently available evidence obtained from studies on animal models and human BRCA1/2 mutation carriers that shows a correlation of BRCA1/2 deficiency with various cardiovascular diseases, including ischemic heart disease, atherosclerosis, and chemotherapy-linked cardiac muscle disorders.

However, it is unclear whether combined treatment with SFN and Zn offers better cardiac protection than either one alone. Here, we treated 5-week-old OVE mice that spontaneously develop type 1 diabetes with SFN and/or Zn for 18 weeks.

In addition, positive feedback regulation between Nrf2 and MT is required for the efficient compensative responses of the heart to IH. As an activator of Nrf2, sulforaphane (SFN) has attracted attention as a potential protective agent against cardiovascular disease.
