Immunohistochemistry technique for effect of gold nanoparticles, laser, and photodynamic therapy on FoxP1 level in infected mice with mammary adenocarcinoma.

The current study was performed to investigate the treatment of tumors with gold nanoparticles, laser, and photodynamic therapy (PDT) by using an immunohistochemistry method and to investigate the expression of FOXP1 in infected mice with mammary adenocarcinoma whether it can be used as an indicator to estimate the recovery of tissues from cancer disease. Twenty-five albino female mice were used in this research; they were divided into five groups, four groups were infected with mammary adenocarcinoma, and then three of them were treated with gold nanoparticles, laser, and PDT, respectively, while the fourth group was left without any treatment and represents the positive control, and the fifth group (normal mice) represents the negative control. Tissue sections were taken from different groups of mice in order to estimate FOXP1 expression in infected mice by using an immunohistochemistry assay.

Plasma proteosome level as a potential marker for hepatocellular carcinoma.

Background And Study Aims: Hepatocellular carcinoma (HCC) is a fatal malignancy. Effective curative surgery is achieved when HCC is detected earlier. Proteosomes, the main non-lysosomal proteolytic structures organising the cellular mechanisms of cleaving proteins, can be considered a tumour marker in many kinds of malignancies.
