In vitro autocrine secretion of inflammatory cytokines in response to drug stress in HCC and LCSC populations

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality. Regardless of its etiology, HCC originates from the constant wound-healing response subsequent to cell death and resulting in a cascade of inflammation. Hence, understanding the importance of inflammatory markers in HCC lies a great importance. A well-known pro-inflammatory cytokine; interleukin-6 has been numerously reported in the sera of HCC patients. This study investigated the effects of IL-6 stimulation in HCC cell line Huh7. After the presence of IL-6R was confirmed, cells were stimulated with recombinant IL-6 to check IL-6’s effect on proliferation, cellular migration, change in the stemness related transcription markers and LCSC markers and lastly, sphere formation capacity. We observed that IL-6 stimulation does not have a significant effect on proliferation, but it increases the migration rate of Huh7 cells significantly. Expression of stemness-related transcription factors such as OCT4 and NANOG, as well as LCSC markers (CD133, and EpCAM) increases significantly. Overall, we concluded that IL-6 plays an important role in HCC and the molecular mechanisms behind this effect needs to be further investigated.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer‐related mortality worldwide. Recent advances in the molecular profiling of HCC emphasize its intratumoral heterogeneity and reveal how cellular pathways are altered in favor of tumor progression. Malignant transformation of primary liver cancer is achieved through the acquisition of cancer hallmark capabilities that promote the uncontrolled proliferation of hepatocytes. In this review, the characteristics and acquired capabilities of huma...
Identification of biomarkers associated with partial epithelial to mesenchymal transition in the secretome of slug over-expressing hepatocellular carcinoma cells

Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths worldwide. Complete epithelial to mesenchymal transition (EMT) has long been considered as a crucial step for metastasis initiation. It has, however, become apparent that many carcinoma cells can metastasize without complete loss of epithelial traits or with incomplete gain of mesenchymal traits, i.e., partial EMT. Here, we aimed to determine the similarities and differences between complete and partial EMT through over-expr...
The Mechanism of anti tumorigenic effects of 15-lox-1 in colon cancer
Çimen, İsmail; Banerjee, Sreeparna; Department of Biology (2012)
Colorectal cancer is the 4th most widespread cause of cancer mortality. One of the pathways that are involved in the development of colorectal cancer is the arachidonic acid metabolizing lipoxygenase (LOX) pathway. Inflammatory molecules formed from this pathway exert profound effects that may exacerbate the development and progression of colon and other cancers. 15 lipoxygenase-1 (15-LOX-1) is a member of LOX protein family that metabolizes primarily linoleic acid to 13-(S)-HODE. Several lines of evidence ...

One of the main problems of current cancer chemotherapy is the lack of selectivity of anti-cancer drugs to tumor cells which leads to systemic toxicity and adverse side effects. In order to overcome these limitations, researches on controlled drug delivery systems have gained much attention. Nanoscale based drug delivery systems provide tumor targeting. Among many types of nanocarriers, superparamagnetic nanoparticles with their biocompatible polymer coatings can be targeted to an intented site by an extern...

Hepatocellular carcinoma (HCC) is one of the most-deadly cancers and the most common type of primary liver cancer. Multikinase inhibitor Sorafenib is one of FDA approved targeted agents in HCC treatment. PI3K/AKT/mTOR pathway is altered in about 51% of HCC; hence, understanding how Sorafenib and PI3K/AKT/mTOR pathway inhibitors act at signaling level is crucial for targeted therapies and to reveal the off-target effects. In this work, we use gene expression profiles (GEPs) of HCC cells (Huh7 and Mahlavu) wh...
