A key feature of many cancers is the capacity and the propensity to metabolize glucose to lactic acid at a very high rate even in the presence of oxygen. This characteristic was first discovered in 1924 by Otto Heinrich Warburg. Hexokinase, the first enzyme in the glycolytic pathway, not only improves the cell's energy supply in malignant cells, bu...

Twist proteins have been shown to contribute to cancer development and progression by impinging on different regulatory pathways, but their mechanism of action is poorly defined. By investigating the role of Twist in sarcomas, we found that Twist1 acts as a mechanism alternative to TP53 mutation and MDM2 overexpression to inactivate p53 in mesenchy...

Biofilms, sedimented microbial communities embedded in a biopolymer matrix cause vast majority of human bacterial infections and many severe complications such as chronic inflammatory diseases and cancer. Biofilms’ resistance to the host immunity and antibiotics makes this kind of infection particularly intractable. Antimicrobial peptides (AMPs) ar...

Therapeutic vaccination offers great promise as an intervention for a diversity of infectious and non‐infectious conditions. Given that most chronic health conditions are thought to have an immune component, vaccination can at least in principle be proposed as a therapeutic strategy. Understanding the nature of protective immunity is of vital impor...

Lung cancer is the leading cause of death in both men and women, constituting a major public health problem worldwide. Non-small-cell lung cancer NSCLC accounts for 85-90% of all lung cancers. We propose a compound that successfully fights the tumor NSCLC growth in vivo by targeting the enzyme GARS1. We present an in-depth investigation of the mech...

The promising anti-angiogenetic properties of previously synthesized pyrazolyl ureas provided the rationale for the synthesis of novel 5-aminopyrazoles 2-5, differently decorated on the pyrazole nucleus. All the derivatives were tested by MTT assays and proved to be non-cytotoxic against eight different tumor cell lines and normal fibroblasts. An E...

Topoisomerases are ubiquitous enzymes in the human body, particularly involved in cancer development and progression. Topoisomerase I (topoI) performs DNA relaxation reactions by "controlled rotation" rather than by "strand passage." The inhibition of topoI has become a useful strategy to control cancer cell proliferation. Nowadays, different compo...

Chemotherapy is used for treatment of all stages of breast cancer, including the metastatic disease and tends to be tailored for each person situation. However, chemotherapeutic agents are the leading cause of serious drug‐related adverse effects and, often, resistance occurs. In this paper, we designed and synthesized a new series of N‐alkylcarbaz...

Drugs delivered by proper carriers enter into the cells much more rapidly and carry out their action much more promptly than in the free forms. A high drug concentration can be sustained for longer periods of time at the target site in the cell. In in vivo conditions, this would translate into a reduction of systemic toxicity, dosage and frequency...
