Abstract:
Lung cancer is one of the most common causes of cancer-related deaths, and drug-resistant lung cancer stem cells (LCSCs) play a significant role in its progression. N6-methyladenosine (m6A) is the most common modification on mRNA. It has been identified as an important epigenetic regulator of LCSC fate. This review focuses on the m6A regulatory machinery in regulating the basic biological functions of LCSCs, involving self-renewal, tumorigenesis, and its metastasis. In addition, this review specifically highlights how m6A modification is dysregulated in LCSCs' resistance to chemotherapy, targeted therapy, and immunotherapy. Moreover, new therapies, like small-molecule inhibitors aimed at enzymes such as METTL3 and FTO that play important roles in m6A are introduced in this review, which could aid in eradicating LCSCs and overcoming treatment failure. m6A pathway is a promising target for discovering new therapies to combat the recurrence of lung cancer.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
