Objective(s): Crocetin, one of the main substances of saffron extract, has anti-cancer effects. Drug resistance proteins (e.g. MRP1 and MRP2) are important reasons for the failure of cancer therapy. We intended to investigate the efficacy of crocetin on MRP1 and MRP2 activity in human ovarian cisplatin-resistant carcinoma cell line (A2780-RCIS).Materials and Methods: The cytotoxic effect of cro...
nanotechnology has slowly but steadily revolutionized the diagnosis, imaging and treatment of cancer. detecting cancer at earliest stages, locating the tumor at different areas in the body and specific delivery of the drugs to malignant cells including surgically inaccessible tumors are the core areas of medical and pharmaceutical research across the world. in this endeavour, nanodevices have e...
Background: Bleomycin (BLM) is an anti-cancer drug widely used in the treatment of cancer. BLM causes several side effects related to DNA and cellular damage. The aim of this study was investigated the effects of tea polyphenol epicatechin on anti-proliferative effects induced by bleomycin in human normal skin and human ovarian cancer cells. Materials and Methods: Human ovarian cancer cell (SK...
background: malignant melanoma is a highly aggressive malignant melanocytic neoplasm which resists against the most conventional therapies. sea cucumber as one of marine organisms contains bioactive compounds such as polysaccharide, terpenoid and other metabolites which have anti-cancer, anti-tumor, anti-inflammatory and antioxidant properties. the present study was designed to investigate the ...
micrornas (mirnas) are non-coding small rna molecules with 21–25 nucleotides. it plays significant role in control of gene expression at posttranscriptional/translational level. they are commonly dysregulated in human cancers, whereas they may behave either as oncogenes or as tumor-suppressor genes. both genetic and epigenetic events in deregulation of mirna can lead to cancer development. gene...
Research on controlled drug delivery for cancer chemotherapy has focused mainly on ways to deliver existing anti-cancer drug compounds to specified targets, e.g., by conjugating them with magnetic particles or encapsulating them in micelles. Here, we show that an iron-salen, i.e., μ-oxo N,N'- bis(salicylidene)ethylenediamine iron (Fe(Salen)), but not other metal salen derivatives, intrinsically...
Colorectal cancer is one of the most frequently diagnosed malignant tumors in men and women, which a highly heterogeneous group neoplasms consisting subclasses with different molecular clinical characteristics, and, as consequence, patients types require treatment protocols. Among predictive factors response metastatic colorectal cancer, studied are genes RAS family (KRAS, NRAS). Determination ...
Abstract Cancer is one of the main causes death worldwide, being pancreatic cancer second deadliest in Western countries. Surgery, chemotherapy and radiotherapy form basis cancer’s current treatment. However, these techniques have several disadvantages, such as surgery complications, systemic side effects recurrence. Drug delivery systems can reduce effects, increasing effectivity treatment by ...
The impact of discontinuation of anti-VEGF cancer therapy in promoting cancer metastasis is unknown. Here we show discontinuation of anti-VEGF treatment creates a time-window of profound structural changes of liver sinusoidal vasculatures, exhibiting hyper-permeability and enlarged open-pore sizes of the fenestrated endothelium and loss of VE-cadherin. The drug cessation caused highly leaky hep...
There is considerable interest in the skin as a site of anti-cancer drug application. Nevertheless, the skin poses a formidable barrier to drug penetration, thereby limiting topical and transdermal bioavailability. However, we previously showed that a thioglycolate-based depilatory agent increases the drug permeability of mouse skin. In the present report, we investigated the skin permeability ...
