Peripheral blood RNA

Peripheral blood RNA modifications as a novel diagnostic signature for polycystic ovary syndrome



Polycystic ovary syndrome (PCOS) is the most prevalent ovulatory and endocrine disorder affecting reproductive-aged women, yet the absence of a specific, rapid molecular diagnostic marker results in diagnostic delays and inaccuracies. Given the critical role of RNA modifications in disease pathology, this study utilized a high-throughput RNA modification profiling platform to investigate 15 types of peripheral blood RNA modification patterns in individuals with ovulatory disorders, including PCOS and primary ovarian insufficiency (POI), and control subjects.

Our results revealed that distinct modification profiles correspond to specific disease states, with significant shifts in RNA modification inter-correlations observed across conditions. Additionally, specific RNA modifications were associated with clinical features, such as serum levels of testosterone and the follicle number per ovary (FNPO).

To optimize diagnostic precision, we evaluated various machine learning models, identifying that combining m6A and m7G modifications in a light gradient boosting machine model (LightGBM) achieves the highest accuracy in distinguishing PCOS, outperforming traditional diagnostic markers. This highlights the potential of RNA modification profiling as a novel, high-accuracy diagnostic tool for PCOS in clinical settings.

Genetic factors with clinical trial stoppage

Genetic factors associated with reasons for clinical trial stoppage Many drug discovery projects are started but few progress fully through clinical trials to approval. Previous work has shown that human genetics support for the therapeutic hypothesis increases the chance of trial progression. Here, we applied natural language processing to classify the free-text reasons for 28,561 clinical trials that stopped before their endpoints were met. We then evaluated these classes in light of the underlying evidence for the therapeutic hypothesis and target properties. We found that trials are more likely to stop because of a lack of efficacy in the absence of strong genetic evidence from human populations or genetically modified animal models. Furthermore, certain trials are more likely to stop for safety reasons if the drug target gene is highly constrained in human populations and if the gene is broadly expressed across tissues. These results support the growing use of human genetics to ...

Post-Stroke Cardiovascular risks

Study finds genetic factors key to post-stroke cardiovascular risks In a recent study published in the journal Stroke , researchers identify genetic and molecular risk factors for subsequent cardiovascular outcomes after incident stroke in an effort to identify potential therapeutic targets to improve patient prognoses. Identifying the causes of stroke Stroke is a major global health issue that causes significant disability and mortality, particularly arterial ischemic stroke (AIS). AIS, which is a type of stroke caused by blocked blood flow to the brain, is responsible for up to 85% of stroke cases. AIS arises due to cerebral blood vessel blockage, with modifiable risk factors including hypertension, diabetes, dyslipidemia, atrial fibrillation, obesity, and lifestyle behaviors. Although genome-wide association studies (GWAS) often focus on incident strokes, studying subsequent events can provide new insights into stroke progression. Further research is crucial to identify genetic and...

Fruitful innovation

Fruitful innovation: Transforming watermelon genetics with advanced base editors The development of new adenine base editors (ABE) and adenine-to-thymine/ guanine base editors (AKBE) is transforming watermelon genetic engineering. These innovative tools enable precise A:T-to-G and A:T-to-T base substitutions, allowing for targeted genetic modifications. The research highlights the efficiency of these editors in generating specific mutations, such as a flowerless phenotype in ClFT (Y84H) mutant plants. This advancement not only enhances the understanding of gene function but also significantly improves molecular breeding, paving the way for more efficient watermelon crop improvement. Traditional breeding methods for watermelon often face challenges in achieving desired genetic traits efficiently and accurately. While CRISPR/Cas9 has provided a powerful tool for genome editing, its precision and scope are sometimes limited. These limitations highlight the need for more advanced gene-e...
