About this video:-
Before going for elaboration of this topic please keep this term in mind which are as follows
The Cell Cycle – A look at the clock-like flow that cells go through when they are growing and dividing.
Cell Division – Covers the control of normal cell division and the defects seen in cancer cells.
Gene Function – Discusses the way genetic information is used in cells.
Mutation – Describes the types and causes of changes to genes (mutations) that can result in cancer.
Cancer Genes – Describes the types of genes (oncogenes and tumor suppressors) that are altered in cancer. Some key examples are given for each type of gene. Contains a section on microRNAs (miRNAs) and their role in cancer.
Cancer Epigenetics – Changes in DNA can be subtle, but have huge impacts on the way cells behave. Epigenetics is the study of these small-but-important changes.
Cancer Cell Death (Apoptosis) – Most cancer drugs are designed to kill cancer cells. The death of cancer cells is a key step in stopping growth, and it happens in a very orderly-fashion.
Metastasis – The majority of cancer deaths are caused by spread of the disease from its orginal location. This section covers the ‘how’ and ‘why’ of cancer spread. Also covered are attempts to interefere with the process in cancer patients.
Invasiveness – is the direct extension and penetration by cancer cells into neighboring tissues. It is generally distinguished from metastasis, which is the spread of cancer cells through the circulatory system or the lymphatic system
Cancer Metabolism – All cells need energy and oxygen to survive. Cancer cells need a lot of energy to reproduce. Often, cancer cells don’t get their energy the same way normal cells do, and this can impact their growth and their response to cancer treatments.
However, the focus of this tutorial will be mainly on the cellular and molecular events that turn a normal cell into a cancerous one. This is a really key issue because if we can get a handle on what is going wrong at the cellular level, we would be able to prevent, diagnose and treat cancer much more effectively.
Often, cancer cells don’t get their energy the same way normal cells do, and this can impact their growth and their response to cancer treatments & Cell Death.
In this video lecture we will discuss about the cancer biology & it’s complete mechanism and components. It is the First part of this video lecture.
Part-2 :- Coming Soon
