Researchers found that hypomethylation, a process triggered by some anti-cancer drugs, can cause tumors in mice. The study suggests that these drugs may do harm as well as good, and highlights the need for further research into the effects of hypomethylation on cancer development in different tissues.
Researchers identify viral protease NS3/4A as a key player in evading the immune system, leading to new avenues for clinical and basic research on hepatitis C. Inhibiting this protease restores the host's immune response, reducing viral levels to nearly undetectable levels.
Researchers studied a gene called Hybrid male rescue in fruit flies and found it altered at an unprecedented rate, speeding up the formation of new species. The work suggests that genetic changes can occur rapidly, driving species divergence.
The editorial highlights China's slow information-gathering from rural districts and secretive attitude to national health statistics as major challenges. A concerted effort to compile accurate statistics on HIV/AIDS prevalence could demonstrate China's ability to learn from its mistakes and acknowledge global responsibilities.
Despite explosive population growth, total harvested area in the region increased by 5%, while irrigated land jumped by 73%. Urbanization appears to have stabilized farm and ranch employment in eastern Colorado Plains cities.
The report, endorsed by national not-for-profit research organizations, urges a 10% increase in the NIH budget to address Alzheimer's, diabetes, and arthritis. This investment could lead to major medical advances and alleviate suffering from aging-related diseases.
A collaborative research group investigated whether Down's syndrome and NTD arise more often in the same family. The study found a significant link between the two conditions, with increased rates of pregnancy loss among families at high risk of NTD and Down's syndrome.
A novel computational method, MiRscan, has been developed to estimate the total number of miRNA genes in different animals. The researchers used this tool to identify 88 miRNA genes in C. elegans and estimated that miRNA genes comprise nearly one percent of the human genome.
A recent study highlights the importance of nurses in reporting adverse drug reactions (ADRs). The research found that the proportion and quality of reports received from nurses were similar to those from doctors. This suggests that nurses can play a valuable part in enhancing pharmacovigilance within the UK.
Researchers at Emory University Health Sciences Center identified a critical molecular link between estrogen receptors and invasive growth in breast cancer. The study reveals that a protein called MTA3 regulates cell adhesion molecule E-cadherin expression, leading to cancer progression.
Researchers discovered that a new class of protease inhibitors can prevent the hepatitis C virus from blocking the innate immune response, restoring it in human cells. This finding suggests that these drugs will have dual efficacy and could become an important addition to existing treatments for hepatitis C.
A study of 1782 first-year university students in Auckland found a high prevalence of recreational nitrous oxide use. The survey revealed that many students were unaware of the potential health risks associated with this substance.
The study reveals a vast array of genomic diversity among the ten newly isolated phages, with varying genome lengths and unexpected similarities to bacterial genomes. This discovery challenges traditional classification systems and raises questions about the role of bacteriophages in evolution.
Researchers found that small toxic molecules triggering cell damage in degenerative diseases have a similar structure. This discovery implies that these molecules are suitable targets for new drugs or vaccines that could halt progression of many degenerative diseases.
Researchers at Dartmouth College have made a breakthrough in producing human therapeutics using a yeast-based protein expression system. By genetically engineering the yeast P. pastoris, they can now produce fully-humanized proteins with complex glycosylation structures.
Researchers found that improved roads convert natural habitats to roadside areas, allowing non-native weeds to spread into adjacent ecosystems. In contrast, native plants thrive closer to roads with typical grassland soils.
Researchers create vancomycin conjugates with buckyballs, which can target specific bacterial antigens and potentially treat resistant strains. The conjugates could also be used to prevent anthrax spores from germinating, offering a new defense against bioterrorism.
Researchers discovered TB bacteria use an error-prone DNA polymerase, DnaE2, to introduce mutations and increase drug resistance. The enzyme plays a key role in the emergence of multidrug-resistant tuberculosis.
Research suggests that exposure to constant white noise delays auditory organization in the brain of rats, which may have implications for human language development. The study found that the brains of noise-exposed rats took longer to develop and mature than those raised in normal conditions.
Researchers discovered that Rad54 and Rad51 proteins form a molecular machine that can repair DNA damage by moving nucleosomes along the strand and stitching new DNA into place. This process becomes more efficient with the addition of Rad51, which binds to single strands of DNA.
A team of UC Berkeley scientists resolves a long-standing puzzle in earth science by clarifying the depth of the continental lithosphere. By re-examining earthquake-generated seismic waves, they determine that the boundary between the lithosphere and asthenosphere lies at 200-250 kilometers.
A study published in Cell identified the function of PPARd, a key receptor that regulates how fat is used. The receptor was found to regulate adaptive thermogenesis, a physiological defense against obesity.
The discovery of organic zeolites with functionalized methyl and methylene groups marks a significant step forward in creating catalysts that mimic enzymes. The incorporation of these organic materials into the structure of silicate-based zeolites could promote novel reactions with improved selectivity.
