Опубликована: Март 11, 2023

Abstract Despite the success of targeted therapies in cancer treatment, therapy-induced resistance remains a major obstacle to complete cure. Tumor cells evade treatments and relapse via phenotypic switching driven by intrinsic or induced cell plasticity. Several reversible mechanisms have been proposed circumvent tumor plasticity, including epigenetic modifications, regulation transcription factors, activation suppression key signaling pathways, as well modification environment. Epithelial-to-mesenchymal transition, stem formation also serve roads towards Corresponding treatment strategies recently developed that either target plasticity-related employ combination treatments. In this review, we delineate plasticity its manipulation evasion from therapy. We discuss non-genetic drug-induced various types tumors provide insights into contribution acquired drug resistance. New therapeutic such inhibition reversal are presented. multitude clinical trials ongoing worldwide with intention improving outcomes. These advances direction for developing novel therapy regimens

Cellular and Molecular Biology of Cancer Stem Cells of Hepatocellular Carcinoma

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(2), С. 1417 - 1417

Опубликована: Янв. 11, 2023

Hepatocellular carcinoma (HCC) is one of the leading causes cancer death globally. The stem cells (CSCs) HCC are responsible for tumor growth, invasion, metastasis, recurrence, chemoresistance, target therapy resistance and radioresistance. reported main surface markers used to identify liver CSCs include epithelial cell adhesion/activating molecule (EpCAM), cluster differentiation 90 (CD90), CD44 CD133. molecular signaling pathways Wnt/β-catenin, transforming growth factors-β (TGF-β), sonic hedgehog (SHH), PI3K/Akt/mTOR Notch. Patients with EpCAM-positive alpha-fetoprotein (AFP)-positive usually young but have advanced tumor-node-metastasis (TNM) stages. CD90-positive HCCs poorly differentiated worse prognosis. Those CD44-positive develop early metastases. CD133 expression a higher recurrence rate shorter overall survival. Wnt/β-catenin pathway triggers angiogenesis, infiltration metastasis through enhancement angiogenic factors. All CD133+ CSCs, CD133+/EpCAM+ CD44+ contribute sorafenib resistance. SHH could protect against ionizing radiation in an autocrine manner. Reducing CSC population crucial improvement HCC. However, targeting still challenging.
