Abstract
Oral cancer is one of the leading causes of cancer-related deaths, and it has become a matter of serious concern due to the alarming rise in its incidence rate worldwide. Despite recent advancements in oral cancer treatment strategies, there are no significant improvements in patient's survival rate. Among the numerous cell signaling pathways involved in oral cancer development and progression, STAT3 is known to play a multifaceted oncogenic role in shaping the tumor pathophysiology. STAT3 hyperactivation in oral cancer contributes to survival, proliferation, invasion, epithelial to mesenchymal transition, metastasis, immunosuppression, chemoresistance, and poor prognosis. A plethora of pre-clinical and clinical studies have documented the role of STAT3 in the initiation and development of oral cancer and showed that STAT3 inhibition holds significant potential in the prevention and treatment of this cancer. However, to date, targeting STAT3 activation mainly involves inhibiting the upstream signaling molecules such as JAK and IL-6 receptors. The major challenge in targeting STAT3 lies in the complexity of its phosphorylation- and dimerization-independent functions, which are not affected by disrupting the upstream regulators. The present review delineates the significance of the STAT3 pathway in regulating various hallmarks of oral cancer. In addition, it highlights the STAT3 inhibitors identified to date through various preclinical and clinical studies that can be employed for the therapeutic intervention in oral cancer treatment.

Abstract
The interleukin-6 (IL-6)/Janus kinase (JAK)/signal transducer and activator of transcription 3 (STAT3) pathway is of crucial importance in promoting tumorigenesis in several malignant tumors but may also be active in benign tumors, e.g., of pleomorphic adenoma (PA). In this study we characterize the expression of the pathway components with immunohistochemistry and selected mRNAs and microRNAs (miRNAs) regulated by this pathway in isolated duct- and myoepithelial cells in PA. 46 PAs were immunostained and 10 of these were used for in situ hybridization (ISH). Six frozen specimens were analyzed using reverse transcription-polymerase chain reaction (RT-PCR). Using immunohistochemistry, IL-6, JAK1, JAK2 and STAT3 were detected significantly more frequently in PA cells than in cells from normal salivary gland tissue. Using RT-PCR cyclin D1, fibroblast growth factor 2, and p21 were found to be overexpressed while matrix metallopeptidase 9 was detected at low levels in PA compared to normal salivary gland. ISH showed significant overexpression of miR-181b in PA, while miR-21 was undetectable in PA and normal tissue. Overexpression of the pathway components and its mRNA and miRNA products provide important clues regarding the growth of PAs. Our findings brings us one step closer to targeted treatment of this tumor entity, although in vitro studies are warranted to confirm this.

Immunohistochemical expression of metallothionein in pleomorphic adenoma of minor salivary glands: a role in the control of apoptosis? Acta Histochem 2013; 115:564-8.

Abstract
Pleomorphic adenoma is the most common benign neoplasm of both the major and minor salivary glands. The histological features are diverse and are characterized by the involvement of epithelial-myoepithelial structures. Metallothionein is a cysteine-rich protein present in myoepithelial cells of several benign and malignant neoplasms. The function of metallothionein is associated with DNA protection, oxidative stress and apoptosis. The purpose of this study was to evaluate the expression of metallothionein in pleomorphic adenoma of the minor salivary glands. Additionally, we investigated the association of the clinicopathological features of the lesions with metallothionein, specifically its association with Bcl-2, in an attempt to evaluate the role of metallothionein in the control of apoptosis. Thirty-five cases of pleomorphic adenoma were selected and immunohistochemistry was performed for metallothionein and Bcl-2 proteins. The proteins were quantified by the Quickscore method. The samples showed epidemiological characteristics similar to those described in the literature. We did not find an association between the clinicopathological characteristics of pleomorphic adenomas and the proteins studied, but an association between metallothionein and Bcl-2 was demonstrated. The results suggest that metallothionein may have a role in the control of apoptosis in pleomorphic adenoma.

Abstract
There is evidence that in the human breast there is a stem cell population that can give rise to many different cell types and have the unique potential to divide asymmetrically. In this way stem cells maintain the stem cell pool and simultaneously generate committed cells that reconstitute the organ for example for preparing the breast for a new pregnancy after the involution from a previous pregnancy and lactation process. In addition to the in vivo models of mammary morphogenesis there are in vitro systems that are more amenable to study in critically determined conditions the ductulogenic pattern of growth of the breast epithelia. Primary mammary epithelial cells grown in collagen matrix are able to form tree-like structures resembling in vivo ductulogenesis. The human breast epithelial cells MCF-10F formed tubules when grown in type I collagen and we demonstrated that treatment of these cells with 17β-estradiol (E(2)) induces phonotypical changes indicative of neoplastic transformation. The transformation of MCF-10F by E(2) is associated with impaired ductal morphogenesis by altering the stem cells unique potential to divide asymmetrically inducing formation of solid masses mimicking intraductal carcinoma that progress to invasive and tumorigenic phenotype. In the present work we present evidence for the mechanism of cell asymmetry leading to normal ductulogenesis and how the normal stem cell is transformed to cancer stem cell by altering this process. Furthermore, we demonstrate that the carcinogenic agent, in this case E(2), induces a defect in the asymmetric cell division program of the normal mammary stem cell.
