Area of Science:

  • Oncology
  • Immunology
  • Molecular Biology

Background:

  • Cancer immunotherapy shows promise but is limited by the lack of tumor-specific targets.
  • Identifying novel biomarkers is crucial for advancing cancer treatment strategies.

Purpose of the Study:

  • To explore novel biomarkers and immunotherapeutic targets against cancer.
  • To investigate the role of SPAG9 as a potential cancer-testis antigen and oncogenic factor.

Main Methods:

  • Exploration of novel biomarkers.
  • Identification and characterization of SPAG9.
  • Assessment of SPAG9's role in oncogenesis across different cancer types.

Main Results:

  • Discovery of a novel cancer-testis antigen, SPAG9.
  • SPAG9 was identified in cancers of diverse histological origins.
  • Demonstrated the potential role of SPAG9 in the process of oncogenesis.

Conclusions:

  • SPAG9 represents a novel cancer-testis antigen with potential as a tumor-specific target.
  • The discovery of SPAG9 opens new avenues for cancer immunotherapy development.
  • SPAG9 may play a significant role in the oncogenesis of various cancers.

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...
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...
Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Cancer-Critical Genes I: Proto-oncogenes01:33

Cancer-Critical Genes I: Proto-oncogenes

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...
