Identifying differentially expressed subpathways connected to the emergence of a disease that can be considered as candidates for pharmacological intervention, with minimal off-target effects, is a daunting task. In this direction, we present a bilevel subpathway analysis method to identify differentially expressed subpathways that are connected with an experimental condition, while taking into account potential crosstalks between subpathways which arise due to their connectivity in a combined multi-pathway network. The efficacy of the method is demonstrated on a hematopoietic stem cell aging dataset, with findings corroborated using recent literature.

Norway maple and sycamore belong to the Acer genus and produce desiccation-tolerant and desiccation-sensitive seeds, respectively. We investigated the seed germination process at the imbibed and germinated stages using metabolomic and proteomic approaches to determine why sycamore seeds germinate earlier and are more successful at establishing seedlings than Norway maple seeds under controlled conditions. Embryonic axes and embryonic axes with protruded radicles were analyzed at the imbibed and germinated stages, respectively.

Adonis amurensis Regel et Radde is a remarkable and important spring ephemeral plant and gained considerable attention because of its remarkable medicinal properties. Extensive research has been conducted on its therapeutic applications, physical characteristics, flowering patterns, reproductive, cultural and molecular biology. However, there is a lack of comprehensive understanding regarding the metabolic changes associated with flower developmental stages.

The high failure rate of surgical repair for tendinopathies has spurred interest in adjunct therapies, including exosomes (EVs). Mesenchymal stromal cell (MSC)-derived EVs (MSCdEVs) have been of particular interest as they improve several metrics of tendon healing in animal models. However, research has shown that EVs derived from tissue-native cells, such as tenocytes, are functionally distinct and may better direct tendon healing.

Reactive oxygen species (ROS) generated by oxidative stress have emerged as critical factors in the pathophysiology of malignancies. This study investigated the antioxidant and anticancer properties of zinc (Zn), selenium (Se), and silver (Ag) nanoparticles (NPs) against the A2780 human ovarian cancer cell line. Here, the bioinformatics approach was used to determine the top differentially expressed genes associated with oxidative stress.

Purpose: Age-related cataract (ARC) remains one of the leading causes of blindness globally. Despite the satisfactory outcomes of surgical interventions, significant disparities in access to medical care prevent many patients from receiving effective treatment. Thus, identifying reliable biomarkers and therapeutic targets to expand treatment options for ARC is essential.
