ABSTRACT
OBJECTIVE: Breast carcinoma is the most common malignant tumor detected in women. The hypothesis that increased levels of adhesion molecules and Cathepsin D affect cancerous cells moving away the primary tumor and contributes to migration of the cancerous cell and may cause remote organ metastases is defended. The aim of the present study was to search the association of intracellular adhesion molecule-1 (ICAM-1), vascular adhesion molecule-1 (VCAM-1), Cyclin D1, cathepsin D immunohistochemically with clinicopathological parameters in the patients diagnosed with invasive ductal breast carcinoma. MATERIALS AND METHODS: The pathological slides of 153 patients diagnosed with invasive ductal carcinoma were evaluated retrospectively. Three groups were created. Group 1 consisted of patients with positive lymph node metastasis and extranodal tumor invasion; Group 2 consisted of patients with positive axillary lymph node metastasis and negative extranodal tumor invasion and Group 3 consisted of the patients with negative axillary lymph node metastasis. In all groups, 20 paraffin blocks belonging to the primary tumor in the breast were stained by ICAM-1, VCAM-1, Cyclin D1 and Cathepsin D. Findings were examined by comparing with clinicopathological parameters. RESULTS: The highest number of metastatic axillary lymph nodes and the highest rate of cathepsin D staining were statistically found in the cases with positive axillary lymph node metastasis and extranodal tumor invasion. CerbB2 was negative in the cases with negative ICAM-1 whereas estrogen receptor and progesterone receptor were positive in the cases with positive VCAM-1. CONCLUSION: The present study reveals significant results for the patients diagnosed with invasive ductal carcinoma through breast biopsy especially before mastectomy in terms of increased number of metastatic axillary lymph nodes and extranodal tumor invasion by immunohistochemical Cathepsin D stain without any additional invasive intervention. Results of the present study may contribute to monitoring and treatment of the patients in the future.

The present study was designed to investigate the effects of zinc and/or melatonin deficiency on rat testes. A total of 24 adult male Sprague-Dawley rats were used in this study. The rats were divided into four groups of six rats each, as follows: (I) controls, (II) zinc deficient, (III) pinealectomized, zinc normal, and (IV) pinealectomized, zinc deficient. The plasma zinc levels in the control group were higher than in all the other groups (p<0.01), and those of the zinc-deficient groups II and IV were significantly lower than for group III (p<0.01). The melatonin levels in the controls were also significantly higher than for all other groups (p<0.01) There was no significant difference in sperm production between the controls and the group of animals that had no epiphysis. A significant suppression was observed in the spermatogenetic activity of the zinc-deficient groups (p<0.01). The suppression was higher in group II than in group IV. These results indicate that testicular damage caused by zinc deficiency may be reduced by melatonin deficiency.
