introduction: low level laser therapy (lllt) also known as photobiomodulation, is a treatment that uses low-level lasers or light-emitting diodes (leds) to change cellular function and is a clinically well accepted tool in regenerative medicine and dentistry. considering the variety of laser, exposure, cells and study types, the exact effects of low level laser therapy seems to be unclear. the ...

Adhesion of epithelial cell to each other and to extracellular matrix, as well as cell migration ability and cytoskeleton organization undergo significant alterations in the course of neoplastic transformation, but regulatory mechanisms involved in these processes are not fully understood. Here, we studied the role of a Rho GAP protein GRAF1 (GTPase Regulator Associated with Focal adhesion kina...

Abstract Background and Aims: To identify and isolation of viruses a susceptible cell is need which can be primary or line. The use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. IRKHBK cell line was originated from primary cells of bovine kidney by continuous passage. The aim of this study was to introduce the IRKHBK cell ...

The low efficiency of conventional therapies in achieving long-term survival of lung cancer patients calls for development of novel options. The potential use of combined gene therapy is under intensive study. One approach uses the expression of genes encoding cytotoxic proteins that affect cellular viability. The gef gene from E. coli, identified as a member of a gene family encoding homologou...

BACKGROUND Cancer is a major health problem and exploiting natural products have been one of the most successful methods to combat this disease. Verbesina encelioides is a notorious weed with various pharmacological properties. The aim of the present investigation was to screen the anticancer potential of V. encelioides extract against human lung cancer (A-549), breast cancer (MCF-7), and liver...

Complexes of 2-(4-thiazolyi)benzimidazole (thiabendazole, THBD) with Co(II), Ni(II), Cu(ll) of general formula ML(2)(NO(3))(2) H(2)O and complexes of Pd(II) and Pt(II) of general formula ML2Cl(2) H(2)O have been obtained and characterized by elemental analyses, IR and far IR spectroscopy and magnetic measurements. The X-ray crystal structure of the copper(II) complex has been determined. The in...

The evolutionarily conserved prohibitin gene is located on human chromosome 17q21, and two alleles have been identified. Our previous studies characterizing prohibitin in immortalized cells, classified into four complementation groups (A-D) based on the ability of whole-cell hybrids to become senescent, have suggested that it has tumor suppressor activity in group B cells. Only the cell lines a...

BACKGROUND Growth inhibition by RPR-130401, a non-peptidomimetic farnesyltransferase inhibitor, was investigated without or with combined exposure to ionizing radiation in three human tumor cell lines (HCT-116, MiAPaCa-2 and A-549) bearing a point mutation in the K-Ras gene. RESULTS RPR-130401 inhibited cell growth with an IC50 of 50 nM (HCT-116), 120 nM (MiAPaCa-2) and 710 nM (A-549), with a...

The high incidence of lung cancer and ineffective toxic action of current mono and doublet chemotherapy approaches result in poor patient survival. Further, matrix metalloproteinases (MMPs) are implicated in neoplastic invasion and metastasis. Based on this, the authors investigated the effect of a dietary micronutrient mixture (NM) containing lysine, proline, arginine, ascorbic acid, and green...
