Motivation: Synergistic drug combinations are a promising approach to achieve a desirable therapeutic effect in complex diseases through the multi-target mechanism. However, in vivo screening of all possible multi-drug combinations remains cost-prohibitive. An effective and robust computational model to predict drug synergy in silico will greatly facilitate this process.
Results: We developed DIGREM (Drug-Induced Genomic Response models for identification of Effective Multi-drug combinations), an online tool kit that can effectively predict drug synergy. DIGREM integrates DIGRE, IUPUI_CCBB, gene set-based and correlation-based models for users to predict synergistic drug combinations with dose-response information and drug-treated gene expression profiles.

Febrile neutropenia is a major complication in patients with acute leukemia or those undergoing hematopoietic stem cell transplantation (HSCT). Understanding patient characteristics and susceptibility patterns in febrile neutropenia is essential for appropriate antimicrobial therapy. First-line agents should have Pseudomonas aeruginosa coverage, but with the increase in multi-drug resistant organisms, ceftazidime-avibactam has emerged as a new therapeutic option.

Novel therapeutic interventions are required to address the critical antimicrobial resistance caused by multidrug-resistant (MDR-PA) infections. This study examines the impact of combining delafloxacin with antibiotics on MDR-PA isolated from various samples. The minimum inhibitory concentrations (MICs) of delafloxacin, alone and in combination with other antibiotics, were determined against forty distinct MDR-PA isolates using the broth microdilution method.

Immune checkpoint inhibitors (ICIs) and their combination with other therapies such as chemotherapy, fail in most cancer patients. We previously identified the PDZ-LIM domain-containing protein 2 (PDLIM2) as a bona fide tumor suppressor that is repressed in lung cancer to drive cancer and its chemo and immunotherapy resistance, suggesting a new target for lung cancer therapy improvement. In this study, human clinical samples and data were used to investigate genetic and epigenetic changes in lung cancer.

, a leading non-tuberculous mycobacterium (NTM) pathogen, causes chronic pulmonary infections, particularly in individuals with underlying lung conditions or immunosuppression. Current treatments involve prolonged multi-drug regimens with poor outcomes and significant side effects, highlighting the urgent need for improved therapies. Using a BALB/c mouse model of chronic pulmonary disease, we evaluated the efficacy of individual antibiotics-clarithromycin, clofazimine, and rifabutin-and combination regimens including clarithromycin+bedaquiline and clarithromycin+clofazimine+bedaquiline.

The incidence of serious lung infections due to Mycobacterium abscessus, a worrying non-tuberculosis mycobacteria (NTM) species, is rising and has in some countries surpassed tuberculosis. NTM are ubiquitous in the environment and can cause serious lung infections in people who are immunocompromised or have pre-existing lung conditions. M.
