Compensatory effects in the PI3K/PTEN/AKT signaling network following receptor tyrosine kinase inhibition [PDF]

open access: yes, 2011
Overcoming de novo and acquired resistance to anticancer drugs that target signaling networks is a formidable challenge for drug design and effective cancer therapy.

Emergence of Anti-Cancer Drug Resistance: Exploring the Importance of the Microenvironmental Niche via a Spatial Model

open access: yes, 2014
Practically, all chemotherapeutic agents lead to drug resistance. Clinically, it is a challenge to determine whether resistance arises prior to, or as a result of, cancer therapy.

miR-218 targets survivin and regulates resistance to chemotherapeutics in breast cancer [PDF]

open access: yes, 2015
Multidrug resistance (MDR) remains one of the most significant obstacles in breast cancer treatment, and this process often involves dysregulation of a great number of microRNAs (miRNAs).

Metabolomics to unveil and understand phenotypic diversity between pathogen populations [PDF]

open access: yes, 2010
Visceral leishmaniasis is caused by a parasite called Leishmania donovani, which every year infects about half a million people and claims several thousand lives. Existing treatments are now becoming less effective due to the emergence of drug resistance.

Systems analysis of drug-induced receptor tyrosine kinase reprogramming following targeted mono- and combination anti-cancer therapy [PDF]

open access: yes, 2014
The receptor tyrosine kinases (RTKs) are key drivers of cancer progression and targets for drug therapy. A major challenge in anti-RTK treatment is the dependence of drug effectiveness on co-expression of multiple RTKs which defines resistance to single ...

Understanding cisplatin resistance using cellular models [PDF]

open access: yes, 2007
Many mechanisms of cisplatin resistance have been proposed from studies of cellular models of resistance including changes in cellular drug accumulation, detoxification of the drug, inhibition of apoptosis and repair of the DNA adducts.

Resisting Bacterial Drug Resistance [PDF]

open access: yesChemistry & Biology, 2003
In this issue of Chemistry & Biology, Wright and colleagues report an elegant method for inhibiting enzymes critical for rendering bacteria drug resistant. By using cationic peptides as inhibitors, the authors have exploited two antibacterial mechanisms, making it doubly difficult for microbial retaliation.

MicroRNA and drug resistance [PDF]

open access: yesCancer Gene Therapy, 2010
Chemotherapy is the preferred treatment for malignancies. However, a successful long-term use of chemotherapy is often prevented by the development of drug resistance. Many mechanisms such as gene mutation, DNA methylation and histone modification have important roles in the resistance of cancer cells to chemotherapeutic agents.

The HIV-1 subtype C epidemic in South America is linked to the United Kingdom.

open access: yesPLoS ONE, 2010
BackgroundThe global spread of HIV-1 has been accompanied by the emergence of genetically distinct viral strains. Over the past two decades subtype C viruses, which predominate in Southern and Eastern Africa, have spread rapidly throughout parts of South

Antimicrobial Resistance of Hypervirulent Klebsiella pneumoniae: Epidemiology, Hypervirulence-Associated Determinants, and Resistance Mechanisms

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Klebsiella pneumoniae is one of the most clinically relevant species in immunocompromised individuals responsible for community-acquired and nosocomial infections, including pneumonias, urinary tract infections, bacteremias, and liver abscesses.
