Protective serum effects in tumor immunity

    Administration of serum presumed to contain tumor-specific antibodies supported the rejection in immunized mice of syngeneic fibrosarcoma implants which receded after an initial period of s.c. growth. Passive transfer of immune serum to unsensitized mice, sublethally radiated and injected with normal lymph node cells, protected the recipients against i.v. but not against s.c. implantation of syngeneic mammary carcinoma cells. Injection of immune serum assisted the recovery of mice in a state of tumor-induced specific immune depression induced by a large. s.c. mammary carcinoma implant and maintained after surgical cure by injections of serum presumed to contain soluble tumor antigen.

    The Tumor Microenvironment02:17

    The Tumor Microenvironment

    Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
    Loss of Tumor Suppressor Gene Functions01:12

    Loss of Tumor Suppressor Gene Functions

    Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
    When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
    Targeted Cancer Therapies02:57

    Targeted Cancer Therapies

    The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
    There are several types of targeted therapies against specific...

    Cancer-Critical Genes II: Tumor Suppressor Genes

    Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
    When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
    Such genes that act...
    Tumor Immunotherapy01:27

    Tumor Immunotherapy

    Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
    Cancer Vaccines01:30

    Cancer Vaccines

    Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
    Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
