Acute and short-term toxicity tests are foundational to toxicology research. These tests offer preliminary insights into the fundamental toxicity characteristics of the chemicals under evaluation and provide essential data for chronic toxicity assessments. Fluoride is a common chemical in aquatic environments; however, the findings of toxicological data, such as LC for aquatic organisms, often exhibit inconsistency.

DNA-damage orchestrates self-renewal and differentiation via reciprocal p53 family and Hippo/Wnt/TGF-β pathway activation in embryonic stem cells.

The mechanism by which DNA-damage affects self-renewal and pluripotency remains unclear. DNA damage and repair mechanisms have been largely elucidated in mutated cancer cells or simple eukaryotes, making valid interpretations on early development difficult. Here we show the impact of ionizing irradiation on the maintenance and early differentiation of mouse embryonic stem cells (ESCs).

Recent advances of antibody-drug conjugates in treating breast cancer with different HER2 status.

Despite the availability of multiple treatment options for breast cancer, challenges such as adverse events, drug resistance, and disease progression persist for patients. The identification of human epidermal growth factor receptor 2 (HER2) as an oncogenic driver in a subset of breast cancers, alongside the development of HER2-targeted therapies, has significantly improved the prognosis of HER2-amplified breast cancers. However, therapeutic options remain limited for HER2-overexpressing or HER2-negative breast cancers.

ALDOA contributes to colorectal tumorigenesis and metastasis by targeting YAP.

Metabolic reprogramming is considered one of the hallmarks of cancer in which cancer cells reprogram some of their metabolic cascades, mostly driven by the specific chemical microenvironment in cancer tissues. The altered metabolic pathways are increasingly being considered as potential targets for cancer therapy. In this view, Aldolase A (ALDOA), a key glycolytic enzyme, has been validated as a candidate oncogene in several cancers.

Microenvironmental β-TrCP negates amino acid transport to trigger CD8 T cell exhaustion in human non-small cell lung cancer.

CD8 T cell exhaustion (Tex) has been widely acknowledged in human cancer, while the underlying mechanisms remain unclear. Here, we demonstrate that reduced amino acid (aa) metabolism and mTOR inactivation are accountable for Tex in human non-small cell lung cancer (NSCLC). NSCLC cells impede the T cell-intrinsic transcription of SLC7A5 and SLC38A1, disrupting aa transport and consequently leading to mTOR inactivation.

Spatial frequency of environments and myopia: A systematic review on associated evidence and underlying mechanisms.
