Cell Cycle and Its Regulation
The cell cycle is a fundamental process that is essential for the growth, development, and maintenance of all living organisms. It is a series of events that a cell undergoes to replicate and divide into two daughter cells. The cell cycle can be divided into two main stages: interphase and mitosis. Interphase is the period…

Molecular genetics of cancer
This topic discusses the molecular genetics of cancer, which involves the study of genetic and molecular changes that occur in cells as they become cancerous. It explains the role of oncogenes and tumor suppressor genes in the development of cancer and how mutations in these genes can disrupt the balance between cell growth and proliferation.…

The APC gene
APC genes are a group of tumor suppressor genes that play a crucial role in preventing the development of colon cancer. Mutations in APC genes can lead to the accumulation of beta-catenin in the cell, which can activate the Wnt signaling pathway and lead to uncontrolled cell growth and the development of tumors. Understanding the…

The RAS gene
This text describes the significance of RAS gene mutations in the development and treatment of cancer. RAS genes play a vital role in regulating cell growth, and mutations in these genes can lead to the development of various cancers, including colorectal, lung, and pancreatic cancer. The three main isoforms of the RAS gene – KRAS,…

Oncogenes and Tumor suppressor genes
The molecular genetics of cancer involves the study of the genetic and molecular changes that occur in cells as they become cancerous. This field of study has led to the identification of two important classes of genes involved in the development of cancer: oncogenes and tumor suppressor genes. Oncogenes promote cell growth and proliferation, while…

Cancer and cell cycle
The article explains the role of the cell cycle in the development of cancer. The cell cycle is a series of events that a cell goes through as it grows and divides into two daughter cells. Disruption in the regulation of the cell cycle can lead to uncontrolled growth and proliferation of cells, causing cancer.…
