Currently, cancer diagnosis relies mostly on morphological examination of exfoliated, aspirated cells or surgically removed tissue. As long as standard diagnosis is concerned, this classical approach seems to be satisfactory. In the recent years, cancer progression has been shown to be accompanied by alterations in mechanical properties of cells. This(More)
The EGFR/PI3K/PTEN/Akt/mTORC1/GSK-3 pathway plays prominent roles in malignant transformation, prevention of apoptosis, drug resistance and metastasis. The expression of this pathway is frequently altered in breast cancer due to mutations at or aberrant expression of: HER2, ERalpha, BRCA1, BRCA2, EGFR1, PIK3CA, PTEN, TP53, RB as well as other oncogenes and(More)
Over the past few years, significant advances have occurred in both our understanding of the complexity of signal transduction pathways as well as the isolation of specific inhibitors which target key components in those pathways. Furthermore critical information is being accrued regarding how genetic mutations can affect the sensitivity of various types of(More)
Integrin linked kinase (ILK) is ubiquitously expressed serine/threonine protein kinase, a binding partner of β1 and β3 integrin subunit as a cytoplasmic effector of integrin receptors that functionally links them to the actin cytoskeleton.We postulate that ILK is important enzyme involved in epithelial-mesenchymal transition (EMT) a critical event in the(More)
OBJECTIVE The aim of this study was to compare the immunohistochemical expression of vascular endothelial growth factors VEGF-C and D, as well as the expression of VEGFR-3 in VIN and vulvar invasive cancer and to compare the density of lymphatic marker D2-40 antibody in both groups, and to compare them with different clinicopathologic features.

Kinetin riboside (KR) is a N6-substituted derivative of adenosine. It is a natural compound which occurs in the milk of coconuts on the nanomole level. KR was initially shown to selectively inhibit proliferation of cancer cells and induce their apoptosis. We observed that KR inhibited growth (20-80%) of not only human cancer, but also normal cells and that(More)
Cervical squamous cell carcinoma (SCC) arises from the metaplastic epithelium and develops slowly through dysplastic changes (i.e., cervical intraepithelial neoplasia--CIN) to carcinoma in situ and invasive cancer. There is little data concerning the quantitation of vascular endothelial growth factor (VEGF) and its correlation to the clinical or pathologic(More)
The mechanisms responsible for the switch of prostate cancer from androgen-sensitive (AS) to androgen-insensitive (AI) form are not well understood. Regulation of androgen receptor (AR), through which androgens control the expression of genes involved in prostate cells proliferation, migration and death also involves its cross-talk with the other signaling(More)
Conjugated linoleic acid (CLA) is a collective term describing a mixture of positional and geometric isomers of linoleic acid with two conjugated double bonds. Among these compounds two isomers cis9, trans11 and trans10, cis12 have received considerable attention. They are present in milk and meat fat of ruminants and the cis9, trans11 (rumenic acid) is the(More)
The roles of the epidermal growth factor receptor (EGFR) signaling pathway in various cancers including breast, bladder, brain, colorectal, esophageal, gastric, head and neck, hepatocellular, lung, neuroblastoma, ovarian, pancreatic, prostate, renal and other cancers have been keenly investigated since the 1980's. While the receptors and many downstream(More)
