The NF-κB signaling pathway is a key regulator of CRC cell proliferation, apoptosis, angiogenesis, inflammation, metastasis, and drug resistance. Over-activation of the NF-κB pathway is a feature of colorectal cancer (CRC). While new combinatorial treatments have improved overall patient outcome; quality of life, cost of care, and patient survival rate have seen little improvement. Suppression of the NF-κB signaling pathway using biological or specific pharmacological inhibitors is a potential therapeutic approach in the treatment of colon cancer. This review summarizes the regulatory role of NF-κB signaling pathway in the pathogenesis of CRC for a better understanding and hence a better management of the disease.

Colorectal cancer (CRC) is one of the leading causes of cancer death worldwide. In more than 90% of all CRC patients, the master oncogenic Ras-Wnt signaling axis is over-activated. MicroRNAs (miRNAs) are potential novel diagnostic and prognostic biomarkers as well as therapeutic targets for several cancers including lung, breast, gastric, and colorectal cancers. Oncogenic or tumor suppressor miRNAs modulate tumor cells proliferation, cell cycle progression, angiogenesis, invasion, and metastasis through regulating oncogenic pathways including Wnt/β-catenin signaling. This review summarizes the current knowledge about the role of Wnt/β-catenin signaling regulatory miRNAs in the pathogenesis of colorectal cancer for a better understanding and hence a better management of this disease.

The red blood cell distribution width (RDW) is an index of the heterogeneity of circulating red blood cell size, which along with other standard complete blood count (CBC) parameters are used to identify hematological system diseases. Besides hematological disorders, several clinical studies have shown that an increased in the RDW may be associated with other diseases including acute pancreatitis, chronic kidney disease, gastrointestinal disorders, cancer, and of special interest in this review, cardiovascular disease (CVD). The diagnostic and prognostic value of RDW in different CVD (acute coronary syndrome, ischemic cerebrovascular disease, peripheral artery disease, atrial fibrillation, heart failure, and acute ischemic stroke) has been reviewed in this article, to provide an understanding how its measurement may be applied to improve the management of these conditions.

Our results suggest that higher depression and anxiety scores are associated with an enhanced inflammatory state, as assessed by higher hematological inflammatory markers including WBC and RDW, even after adjusting for potential confounders.

Colorectal-cancer (CRC) is the third leading cause of death due to cancer, supporting the need for identification of novel anticancer drug to improve the efficacy of current-therapy. There is growing bodies of data showing the antitumor-activity of curcumin, although it is associated with low absorption. The aim of current study was explored the therapeutic-potential of novel phytosomal curcumin as well as its application in combination with 5-Flurouracil (5-FU) in a mouse-model of colitis-associated colon-cancer. The anti-proliferative-activity of phytosomal curcumin was assessed in 2- and 3-dimensional cell-culture-models as well as in a mouse-model of colitis-associated colon-cancer. The expression-levels of CyclinD1, beclin, E-cadherin, and p-GSK3a/b were investigated by qRT-PCR and/or Western-blotting. We evaluated the anti-inflammatory of this agent by pathological-evaluation and disease-activity-index (DAI). Moreover, oxidant/antioxidant activity was examined by malondialdehyde (MDA), total-thiols (T-SH), superoxide-dismutase (SOD), and catalase (CAT) activity parameters. Our data showed that phytosomal curcumin and its combination with 5-FU inhibited cell growth and invasive behavior of CRC cells through modulation of Wnt-pathway and E-cadherin. Combination of curcumin with 5-FU dramatically reduced the tumor-number and tumor-size in both distal and middle parts of colon in colitis-associated colon cancer followed by reduction in DAI. Also, curcumin suppressed the colonic inflammation and notably recovered the increased levels of MDA, decreased thiol level and reduced activity of CAT. We demonstrated the antitumor-activity of novel form of curcumin in CRC, supporting further investigations on the therapeutic-potential of this approach in colorectal-cancer.

Wnt5a initiates pro-inflammatory responses through activation of non-canonical Wnt signaling pathway. Pro-inflammatory functions of Wnt5a trigger pro-inflammatory signaling cascades and increase secretion of pro-inflammatory cytokines and chemokines. Wnt5a as a potent signaling molecule is strongly implicated in a number of diseases including cancer, diabetes, metabolic disorders, and of special interest in this review, inflammatory diseases. This review summarizes the role of Wnt5a in the pathogenesis of inflammatory diseases including atherosclerosis, rheumatoid arthritis, psoriasis vulgaris and sepsis, promoting greater understanding, and clinical management of these diseases.

Hepatocellular carcinoma (HCC) is one of the common malignant human tumors with high morbidity worldwide. Aberrant activation of the oncogenic phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) signaling is related to clinicopathological features of HCC. Emerging data revealed that microRNAs (miRNAs) have prominent implications for regulating cellular proliferation, differentiation, apoptosis, and metabolism through targeting the PI3K/AKT/mTOR signaling axis. The recognition of the crucial role of miRNAs in hepatocarcinogenesis represents a promising area to identify novel anticancer therapeutics for HCC. The present study summarizes the major findings about the regulatory role of miRNAs in the PI3K/AKT/mTOR pathway in the pathogenesis of HCC.

Colorectal cancer (CRC) is the leading cause of cancer death worldwide. Dysregulation of RAS/MAPK signaling axis is frequently found in CRC patients.The RAS/MAPK axis regulates cancer cell proliferation, apoptosis, inflammation, migration, and metastasis. Oncogenic or tumor-suppressor microRNAs (miRNAs) for RAS/MAPK signaling play a key role in the pathogenesis of CRC and are considered as novel potential biomarkers for diagnosis and prognosis of human malignancies. This review summarizes the current knowledge of mechanisms of action of RAS/MAPK miRNAs in the development and progression of CRC for a better understanding and hence a better management of this disease.
