Leiomyosarcoma (LMS) is a malignant neoplasm with smooth muscle differentiation. Little is known about its molecular heterogeneity and no targeted therapy currently exists for LMS. We performed expression profiling on 99 cases of LMS with 3'end RNA sequencing (3SEQ) and demonstrated the existence of 3 molecular subtypes in this cohort. We consequently showed that these molecular subtypes are re...
AIM The invasive mammary cancer is the most frequent malign tumor of a woman. Among the potential prognostic factors are included the biomarkers which measure or are associated with biological processes involved in the tumoral progression. We study the prognostic importance of the c-erbB2 oncoprotein in the invasive mammary cancer. MATERIAL AND METHODS We included in the study 56 female patie...
The effects of enalapril on p53 expression in left ventricular cardiomyocytes after aortic stenosis.
ACE-inhibitors prevent the development of left ventricular hypertrophy (LVH). The tumor suppressor gene p53 up-regulates the cellular renin-angiotensin system, resulting in ANG II synthesis, which activates p53 creating a positive feedback loop. One hundred and fourteen rabbits were separated into groups A (control), B (sham-operated), C and D. In groups C and D, an aortic stenosis was performe...
To reveal the molecular mechanism of selective follicular atresia in porcine ovaries, we investigated the changes in the expression of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its receptor (DR4) proteins and TRAIL mRNA in granulosa cells during follicular atresia. Immunohistochemical, Western immunoblotting and reverse transcription-polymerase chain reaction analyses ...
S-nitrosoglutathione (GSNO) is considered a natural nitric oxide (NO.) reservoir and a reactive nitrogen intermediate in animal cells, but little is known about this molecule and its metabolism in plant systems. In this work, using pea plants as a model system, the presence of GSNO in collenchyma cells was demonstrated by an immunohistochemical method. When pea plants were grown with a toxic Cd...
One of the most used ancillary techniques by surgical pathologists in clinical practice is immunohistochemistry (IHC) that, through an antibody–antigen reaction, allows for detection specific proteins at cellular level [...]
