Article Abstract
Background: In the majority of cancers, metastasis of tumor cells is the main cause of treatment failure. This study intended to investigate the effectiveness of basic fibroblast growth factor (bFGF) peptide designed to inhibit tumor growth in 4T1 metastatic breast cancer through the PI3K/AKT and ERK/MAPK signal transduction pathways.
Methods: The tumor was induced through 4T1 tumor graft in BALB/c mice. The designed peptide was injected intraperitoneal at three selected doses after two weeks for 14 days. The PBS and doxorubicin were used as the negative and positive control groups, respectively. Tumor size was measured and after the treatment period, the mice underwent a surgery and tumors were used for the western blot examinations.
Results: the peptide injection was effective in reducing or inhibiting tumor growth in mice model and in vitro. The western blot analysis results showed that the p-AKT and p-ERK levels in peptide treated tumors were reduced (p<0.05).
Conclusion: The peptide injection was effective in mice model. Findings showed that in the two signal transduction pathways, the p-AKT and p-ERK levels were significantly different from the negative control group.

Circulating levels of 3-carboxy-4-methyl-5-propyl-2-furanpropionic acid (CMPF), a metabolite derived from dietary furan fatty acids primarily found in marine food sources, have long been recognized as biomarkers for fish intake. However, elevated CMPF levels are also observed in patients with type 2 diabetes or chronic kidney disease and in healthy people associated with a reduced infection risk, suggesting potential bioactive roles in metabolism and immune function. Yet, the possible causal mechanisms behind these associations are unknown.

Background: Studies on the interaction of cancer cells with other cells (fibroblasts, endothelial cells, and immune cells) of the tumor microenvironment (TME) have led to the development of many novel targeted therapies. More recently, the notion that neuronal cells of the TME could impact various processes supporting cancer progression has gained momentum. Tumor-associated neurons release neurotransmitters into the TME that, in turn, bind to specific receptors on different target cells, supporting cancer progression.

Renal ischemic disease represents a severe clinical pathological condition commonly observed in acute kidney injury (AKI), renal transplantation, and kidney surgery. It leads to renal tubular epithelial cell damage, inflammatory responses, and cell death, potentially progressing to chronic kidney disease (CKD) or even renal failure, significantly impairing patients' quality of life and survival rates. Current therapeutic strategies for renal ischemia-reperfusion injury (IRI) include pharmacological interventions, cell therapy, and gene therapy, yet their efficacy remains limited and may be accompanied by adverse effects.

Maxillary underdevelopment is a critical component of skeletal Class III malocclusion, closely linked to altered biomechanical signaling. Mechanical stimulation through early facemask protraction can effectively promote maxillary growth, yet the underlying mechanotransduction mechanisms remain unclear. In this study, fibroblast growth factor 9 (FGF9) is identified as a key biomechanical responder in maxillary development.

Background And Objective: Periodontitis is a chronic inflammatory disease driven by immune dysfunction and microbial imbalance. This study aims to identify circulating druggable proteins causally linked to the disease.
Materials And Methods: We integrated proteomics data from deCODE genetics with periodontitis genome-wide association studies (GWAS) from the Million Veteran Program to identify proteins associated with periodontitis.
