The clinical impact of exosomes in cardiovascular disorders: from basic science to clinical application

Cardiovascular disease (CVD) is the major cause of death globally; therefore, there is a need for the identification of valid biomarker that accurately predict the risk of developing cardiovascular disease, and novel therapeutic approaches for its treatment. Exosomes are very small extracellular vesicles containing protein, lipid, transcription factors, mRNAs, non-coding RNA and nucleic acid contents, that are important players in intercellular communication, and that act via long-range signals or cell-to-cell contact. The discovery of exosomes provides potential strategies for the diagnosis and treatment of cardiovascular disease. In the current review, we have explored the potential impact of exosomes on cardiovascular physiology, and their therapeutic potential in cardiovascular disorders with a emphasize on the existing preclinical studies

Clinical Importance of Wnt5a in the Pathogenesis of Colorectal Cancer

Wnt5a is one of the potent signaling molecules that initiates responses involved in cancer through activation of both canonical and noncanonical signaling cascades. Wnt5a both directly and indirectly triggers cancer-associated signaling pathways based on the cancer type. In colorectal cancer (CRC), altering Wnt5a expression can influence several cellular processes of tumor cells, including proliferation, differentiation, migration, invasion, and metastasis. This review summarizes the molecular mechanisms and clinical importance of Wnt5a in the pathogenesis of CRC for better understanding the pathogenesis and its potential role as a prognostic marker and as an appropriate therapeutic target in the treatment of this disease in the future.</jats:p

Therapeutic Effects of Polyphenols on the Treatment of Colorectal Cancer by Regulating Wnt β-Catenin Signaling Pathway

Colorectal cancer (CRC) is the third most common cause of cancer-related death worldwide in terms of both its rates of incidence and mortality. Due to serious side effects associated with conventional chemotherapeutic treatments, many natural products with fewer adverse side effects have been considered as potential treatment options. In fact, many natural products have widely been used in various phases of clinical trials for CRC, as well as in in vitro and in vivo preclinical studies. Curcumin (CUR) and resveratrol (RES) are classified as natural polyphenolic compounds that have been demonstrated to have anticancer activity against CRC and are associated with minimal side effects. By regulating select target genes involved in several key signaling pathways in CRC, in particular, the Wnt β-catenin signaling cascade, the course of CRC may be positively altered. In the current review, we focused on the therapeutic effects of CUR and RES in CRC as they pertain to modulation of the Wnt β-catenin signaling pathway.</jats:p

Cancer stem cells: An overview of the pathophysiological and prognostic roles in colorectal cancer

Colorectal cancer (CRC) is one of the most common types of cancer globally. A subpopulation of tumour cells, cancer stem cells (CSC), is speculated to be responsible for tumor initiation, development, maintenance, metastasis, and recurrence. Colorectal cancer stem cells (CRC-SCs) have demonstrated some unique features, including a high level of heterogeneity and plasticity. This review summarizes the current understanding of CRC-SCs in the progression of CRC and the prognostic importance of these CSCs and their markers in colorectal cancer. Moreover, we have also discussed about various therapeutic approaches against markers-expressing CRC-SC

The Therapeutic Potential of MAPK/ERK Inhibitors in the Treatment of Colorectal Cancer

: The MAPK/ERK signaling pathway regulates cancer cell proliferation, apoptosis, inflammation, angiogenesis, metastasis and drug resistance. Mutations and up-regulation of components of the MAPK/ERK signaling pathway, as well as over-activation of this critical signaling pathway, are frequently observed in colorectal carcinomas. Targeting the MAPK/ERK signaling pathway, using specific pharmacological inhibitors, elicits potent anti-tumor effects, supporting the therapeutic potential of these inhibitors in the treatment of CRC. Several drugs have recently been developed for the inhibition of the MEK/ERK pathway in preclinical and clinical settings, such as MEK162 and MK-2206. MEK1/2 inhibitors demonstrate promising efficacy and anticancer activity for the treatment of this malignancy. This review summarizes the current knowledge on the role of the MAPK/ERK signaling pathway in the pathogenesis of CRC and the potential clinical value of synthetic inhibitors of this pathway in preventing CRC progression for a better understanding, and hence, better management of colorectal cancer. </jats:sec
