Scientists find link between estrogen metabolism pathway and breast cancer risk

A large-scale study involving over 7,700 participants found a positive association between DNA polymorphisms related to estrogen production and breast cancer development. The research suggests that combining multiple genetic markers can estimate breast cancer risk and may lead to the development of new prevention and treatment strategies.

Gene that improves quality of reprogrammed stem cells identified by Singapore scientists

Researchers at the Genome Institute of Singapore have identified the genetic molecule Tbx3, which significantly improves the quality of induced pluripotent stem cells (iPS cells). The study successfully produced iPS cells that can recapitulate entire developmental processes and exhibit superior ability for germ-line transmission.

Scientists map epigenome of human stem cells during development

Researchers created a detailed map of the human epigenome during embryonic development, identifying patterns of DNA methylation and its role in regulating gene expression. This breakthrough has significant implications for targeted differentiation of stem cells into specific organs, a crucial consideration for stem cell therapy.

Leprosy susceptibility genes reported in New England Journal of Medicine paper

A large-scale genetic study has identified seven genes that increase an individual's susceptibility to leprosy, a chronic infectious disease affecting skin and peripheral nerves. The discovery highlights the role of innate immune response in leprosy development and may lead to early diagnosis and treatment.

First 'genetic map' of Han Chinese may aid search for disease susceptibility genes

Scientists at the Genome Institute of Singapore have created a genetic map of the Han Chinese population based on genome-wide DNA variations in over 6,000 samples. The map reveals that northern inhabitants were genetically distinguishable from those in the south, consistent with historical migration patterns.

Singapore scientists join international study of 10,000 vertebrates' genomes

The Institute of Molecular and Cell Biology in Singapore joins an international effort to sequence the genomes of 10,000 species, enabling comparisons between animal and human genomes. This will help scientists understand evolutionary changes and predict responses to climate change, pollution, and disease.

Singapore scientists discover widely sought molecular key to understanding p53 tumor suppressor gene

Researchers at Singapore Immunology Network (SIgN) have identified the molecular key to understanding the p53 tumor suppressor gene's function. The discovery reveals how p53 regulates genes by recognizing specific sequences of nucleotides in DNA, providing a missing piece to this complex biological process.

New ultrasensitive electronic sensor array speeds up DNA detection

Scientists developed a novel electronic sensor array to rapidly detect DNA for disease diagnosis and biological research, with ultrasensitive detection capabilities and cost-effectiveness. The Nanogap Sensor Array technology has the potential to speed up efforts in detecting debilitating diseases such as cancer and infectious viruses.

Unique immunization method provides insights about protective anti-malaria immune response

Scientists developed a novel immunization method that induces complete protection against the life-threatening malaria parasite in humans. The method allowed the human immune system to target the parasite at an earlier stage of its life cycle, resulting in significant improvement over other experimental malaria vaccines.

1 gene that contributes to breast cancer's aggressive behavior identified

Researchers at Genome Institute of Singapore identify RCP as a novel breast cancer promoting gene that functionsally contributes to aggressive breast cancer behaviour. Over-expression of RCP is positively correlated with cancer recurrence in patients, and silencing the gene significantly diminishes tumour formation and metastasis.

Gene's novel role may provide key to treating liver and neurodegenerative diseases

Researchers at the Bioprocessing Technology Institute discovered a novel function of the FAIM gene, which protects immune and liver cells from apoptosis. They propose that manipulating this process could lead to new treatments for liver cirrhosis and neurodegenerative diseases like Alzheimer's and Parkinson's.

Novel discovery in dendritic cell signalling pathways pave the way for new therapeutic targets

Scientists have discovered a novel signaling pathway in dendritic cells that can be activated by bacterial fragments, leading to the activation of NFAT and triggering an immune response. This discovery has identified potential new therapeutic targets for diseases such as sepsis and chronic heart failure.

New 3-D structural model of critical H1N1 protein developed

Researchers at the Bioinformatics Institute in Singapore have created a 3D structural model of the neuraminidase protein, which is critical to the H1N1 influenza A virus. This breakthrough analysis revealed extensive surface mutations compared to closely related strains, making previous flu vaccinations less effective. The study also f...

Singapore scientists synthesize gold to shed light on cells' inner workings

Researchers at the Institute of Bioengineering and Nanotechnology have synthesized gold nanoclusters that can be used for sub-cellular biolabeling and bioimaging. These clusters are suitable for use within the body due to their lack of toxic metals, enabling scientists to monitor cell nucleus dynamics and study genomic changes.

Regulatory molecule for tumor formation or suppression identified by Singapore, US researchers

Researchers at Singapore's Genome Institute of Singapore and the US have identified microRNA-125b as a novel regulator of the p53 tumor suppressor gene. The study found that this microRNA keeps p53 levels low during embryonic development, but allows for an increase in p53 to prevent tumor formation if DNA is damaged. Elevated levels of...

Elephant shark genome sequence leads to discovery of color perception in deep-sea fish

A research team from Singapore and London has discovered that the elephant shark, a primitive deep-sea fish, possesses three cone pigments for color vision similar to humans. The finding suggests that gene duplication played a crucial role in this process, which may provide valuable insights into human genome evolution.
