RUDN pharmacists proposed ways to increase the activity of levofloxacin and overcome bacterial resistance to antimicrobial agents

RUDN University pharmacists modeled derivative molecules of the antibacterial levofloxacin to find out what biological functions its individual structural fragments – pharmacophores – are responsible for. This is necessary to increase the effectiveness of the drug, as bacteria become increasingly resistant to antibiotics.

Second gene implicated in malaria parasite resistance evolution to chloroquine

How malaria parasites evolved to evade a major antimalarial drug has long been thought to involve only one key gene. Now, thanks to a combination of field and lab studies, an international research team has shown a second key gene is also involved in malaria’s resistance to the drug chloroquine.

UNLV, SNWA Study Makes Case for Candida Auris Wastewater Surveillance

A rapid spike in cases of a potentially deadly, drug-resistant fungus has concerned public health officials across the nation. But a team of Southern Nevada researchers hope their new study applying wastewater surveillance can help health officials get a step ahead of this emerging global public health threat.

National Researcher of the Year 2022 Decodes Drug Resistance in Animals – A Step towards Sustainable Solutions

Chula Veterinary Lecturer and “National Outstanding Researcher 2022” has revealed the genetic code that causes drug resistance in animals that affects human health, animals, and the environment, and suggests comprehensive solutions under the concept “One Health”.

Computer Simulations of Proteins Help Unravel Why Chemotherapy Resistance Occurs

Understanding why and how chemotherapy resistance occurs is a major step toward optimizing treatments for cancer. A team of scientists including Markus Seeliger, PhD, of the Renaissance School of Medicine at Stony Brook University, believe they have found a new process through which drug resistance happens.

Researchers uncover how tumors circumvent prostate cancer therapy, identify promising treatment strategy

A Cleveland Clinic-led research team uncovered how tumors circumvent prostate cancer therapy and identified a promising new strategy for treatment. Findings were published in Proceedings of the National Academy of Sciences (PNAS). Antiandrogen strategies remain the backbone for advanced prostate…

Avoiding Drug Resistance by Understanding Evolution of Viruses

During ACA’s 71st annual meeting, Celia Schiffer, from the University of Massachusetts, will talk about her lab’s work with virus substrate recognition as a method to avoid drug resistance. Schiffer and her team expanded their work on HIV and the hepatitis C virus to include human T-cell lymphotropic virus type 1 and SARS-CoV-2, the virus that causes COVID-19, and discovered that designing robust inhibitors to fit within the substrate envelope tips this balance toward decreasing the probability of resistance.

Why It Matters: Prescription for Disaster

Bacteria are becoming increasingly resistant to antibiotics. A major cause is their overuse in both humans and animals. At the same time, a lack of financial incentives is setting back efforts to discover new classes of antibiotics. The problem is both global and local, and without new initiatives, many common medical conditions could become deadly once again.

Calcium Signaling Identified as Exploitable Target in Addressing Drug Resistance to Non-Hodgkin Lymphoma Treatment

Gene expression profiling and other analyses conducted by Rutgers Cancer Institute of New Jersey researchers and colleagues examining drug resistance to a common antibody therapy for non-Hodgkin lymphoma have identified calcium signaling as a novel and exploitable target in overcoming this treatment obstacle. Results are being presented at the American Society of Hematology Annual Meeting.

Single Mutation Dramatically Changes Structure and Function of Bacteria’s Transporter Proteins

Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study published in the journal eLife. The study—conducted using E. coli bacteria—can help researchers to better understand the evolution of transporter proteins and their role in drug resistance.
