Researchers found that prion infection influences the expression of endogenous retroviruses in mouse cells, with some sequences increasing and others decreasing. The effects could be suppressed by an anti-prion drug, suggesting a possible link between prions and retrovirus production.
A study of over 300,000 genetic markers found a strong association between the ORMDL3 gene and an increased risk of childhood asthma. The research suggests that identifying this gene could lead to improved prevention and diagnosis of asthma.
A research team has identified a genetic deficiency that causes severe blindness, specifically Leber Congenital Amaurosis (LCA). The discovery of the LCA5 gene and its protein lebercilin provides new opportunities for gene therapy, which could lead to the treatment of this disease in humans.
A study published in Nature Genetics has identified three genes associated with restless legs syndrome (RLS), a condition characterized by an urge to move and paresthesia in the legs. The findings provide new insights into the genetic causes of RLS, which affects up to 10% of people over 65 years old.
A phase III study of 341 high-risk patients with deep, local sarcomas shows significant improvement in tumour response and survival rates when treated with a combination of chemotherapy and local, deep hyperthermia. The combined therapy has been applied to patients before surgery, demonstrating its effectiveness.
A study published in Journal of Allergy and Clinical Immunology found that exposure to cat allergens at home increases the frequency of allergic sensitization in young children. The study analyzed data from over 1,000 children born between 1997 and 1999 and found that even brief contact with cat hair can lead to sensitization.
Scientists discovered a new strategy for bacterial communication called efficiency sensing, which combines existing theories of quorum sensing and diffusion sensing. This approach takes into account the spatial distribution of bacteria, addressing the limitations of traditional models.
A new assay allows simultaneous detection of individual proteins and their interactions in living cells, enabling researchers to monitor protein expression and interaction networks. This breakthrough method has the potential to develop novel antiviral factors and therapies for infectious diseases and cancers.
