lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

8.9K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Cancer-Critical Genes II: Tumor Suppressor Genes

7.9K
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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.8K
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...

Loss of Tumor Suppressor Gene Functions

5.1K
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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

6.8K
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...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

5.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Area of Science:

  • Immunology
  • Oncology
  • Cytokine Biology

Background:

  • Thymic stromal lymphopoietin (TSLP) is an alarmin cytokine with diverse biological activities.
  • TSLP signals through a heterodimeric receptor complex involving TSLP receptor (TSLPR) and IL-7Rα.
  • Primarily produced by epithelial cells, TSLP also originates from immune cells and cancers, influencing inflammation, angiogenesis, and tumorigenesis.

Purpose of the Study:

  • To review recent advances in TSLP immunobiology concerning human and experimental cancers.
  • To discuss the dual role of TSLP as a Janus cytokine in tumorigenesis.
  • To highlight the potential of anti-TSLP therapies in cancer treatment.

Main Methods:

  • Literature review of TSLP's role in cancer.
  • Analysis of TSLP's involvement in immune cell activation.
  • Examination of preclinical data, including the efficacy of anti-TSLP monoclonal antibodies in cancer models.

Main Results:

  • TSLP plays a significant role in the development of various human hematologic and solid tumors.
  • Contradictory findings exist regarding TSLP's precise role in different cancer types.
  • An anti-TSLP monoclonal antibody demonstrated protective effects in a mouse model of colorectal cancer.

Conclusions:

  • TSLP is implicated in both cancer development and progression.
  • Further research into TSLP's multifaceted role in tumorigenesis is crucial.
  • Targeting TSLP with monoclonal antibodies represents a promising therapeutic strategy for certain cancers.
