Also, has cytotoxic activity in the triple-negative subtypes, HER2+, and luminal A of breast cancer cells, with its properties being associated with an effect on the antiapoptotic function of Hexokinase II (HKII). : In this research, we reviewed the altered levels of proteins present in the lymph nodes of male Balb/c mice inoculated with U-937 cells and treated with or methotrexate, as well as mice only inoculated with cancer cells.

The Metabolism of Creatinine and Its Usefulness to Evaluate Kidney Function and Body Composition in Clinical Practice.

Serum creatinine levels are the most used clinical marker to estimate renal function as the glomerular function rate because it is simple, fast, and inexpensive. However, creatinine has limitations, as its levels can be influenced by factors such as advanced age, physical activity, protein-rich diets, male gender, medications, and ethnicity. Serum cystatin C and its combination with serum creatinine may serve as an alternative since these factors do not affect it.

Exploring the Mechanisms Underlying Cellular Uptake and Activation of Dendritic Cells by the GK-1 Peptide.

The use of peptides for cancer immunotherapy is a promising and emerging approach that is being intensively explored worldwide. One such peptide, GK-1, has been shown to delay the growth of triple-negative breast tumors in mice, reduce their metastatic capacity, and reverse the intratumor immunosuppression that characterizes this model. Herein, it is demonstrated that GK-1 is taken up by bone marrow dendritic cells in a dose-dependent manner 15 min after exposure, more efficiently at 37 °C than at 4 °C, implying an entrance into the cells by energy-independent and -dependent processes through clathrin-mediated endocytosis.
