The metalloproteinases MMP-9 and MT1-MMP play a pivotal role in extracellular matrix remodeling, thereby facilitating tumor growth and metastasis. Tumor progression requires the degradation of the basement membrane. The principal components of this structure, namely collagen IV and laminin, are the main targets of both MMP-9 and MT1-MMP. However, they can also exert influence over the expression of these enzymes. Oxidative stress plays an instrumental role in tumor development, functioning as a key inducer of metalloproteinase expression. The present study investigates the distribution of MMP-9 and MT1-MMP within tumor nests and along the basement membrane, comparing these with the distributions of collagen IV, laminin-332, and the antioxidant MnSOD. Biopsies from 12 patients with HNSCC and poor prognostic factors were subjected to immunofluorescence analysis. MMP-9 and MT1-MMP were found to be predominantly present in tumor cells, with a significant decrease in expression from the periphery to the center of tumor nests. Co-localization studies with laminin-332 and collagen IV, revealed substantial overlap, in accordance with the role of MMPs in basal membrane degradation. The cellular expression of laminin-332 associated with MMP-9 expression suggests an intricate relationship between metalloproteinases and their targets.

Chemotherapy, radiotherapy, and surgery are among the treatments available for endometrial cancer. Currently, drugs used for chemotherapy have had limited success in increasing the cure rate. Betulinic acid, a lupane-type triterpene widely found in the plant kingdom, has attracted attention for cancer treatment in recent years due to its ability to inhibit tumor growth and induce cell apoptosis. The aim of this study is to investigate the mTOR pathway-mediated anticancer effects of betulinic acid in human endometrial cancer cells. The effect of betulinic acid on Ishikawa cell viability was determined by the CCK-8 method. Its effect on the expression of genes involved in apoptosis and the mTOR pathway was assessed by real-time PCR. The effect on protein expression in the mTOR pathway was evaluated with immunohistochemistry and western blot, and the effects on apoptosis via Annexin V. Betulinic acid reduced Ishikawa endometrial cancer cell proliferation. Betulinic acid administration caused a significant decrease in Bcl2 (<i>P</i>=0.008) expression and increased caspase-8 (<i>P</i>=0.001) expression in Ishikawa cells. The results of Annexin V supported the idea that betulinic acid administration triggered apoptosis in Ishikawa cells. The mean rate of apoptotic cells in the betulinic acid group was 22±3.23%, while it was 2.31±0.2% in the control group (<i>P</i>=0.02).
