Insights

Long non-coding RNA FGF13-AS1 acts as a tumor suppressor in breast cancer by inhibiting cell proliferation, migration, and invasion. Its downregulation is linked to poor prognosis, suggesting a new therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Long non-coding RNAs (lncRNAs) are critical in breast cancer development.
  • LncRNA FGF13-AS1 is downregulated in breast cancer and associated with poor prognosis.

Purpose of the Study:

  • To investigate the role of FGF13-AS1 in breast cancer.
  • To elucidate the underlying molecular mechanisms of FGF13-AS1 action.

Main Methods:

  • Analysis of FGF13-AS1 expression in breast cancer tissues.
  • Functional assays to assess the impact of FGF13-AS1 on cell proliferation, migration, and invasion.
  • Mechanistic studies involving RNA-binding proteins (IGF2BPs) and c-Myc mRNA stability.

Main Results:

  • FGF13-AS1 expression is decreased in breast cancer tissues.
  • FGF13-AS1 suppresses breast cancer cell proliferation, migration, and invasion by impairing glycolysis and stemness.
  • FGF13-AS1 reduces c-Myc mRNA half-life by interacting with IGF2BPs, and c-Myc transcriptionally inhibits FGF13-AS1, forming a feedback loop.

Conclusions:

  • FGF13-AS1 acts as a tumor suppressor in breast cancer.
  • The FGF13-AS1/IGF2BPs/Myc feedback loop represents a potential therapeutic target for breast cancer treatment.

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Cell Signaling Feedback Loops

Positive and negative feedback loops are crucial for regulating biological signaling systems. These feedback loops are processes that connect output signals to their inputs.
Negative feedback loops
Most signaling systems have negative feedback loops that can perform different functions such as output limiter, and adaptation.
Output limiter
Upon receiving an input signal, the cellular response rapidly increases until a threshold is reached. Beyond this threshold, a negative feedback loop...

lncRNA - Long Non-coding RNAs

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...

Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires  maintaining an internal dynamic equilibrium:

What is Glycolysis?00:56

What is Glycolysis?

Overview
Cells make energy by breaking down macromolecules. Cellular respiration is the biochemical process that converts "food energy" (from the chemical bonds of macromolecules) into chemical energy in the form of adenosine triphosphate (ATP). The first step of this tightly regulated and intricate process is glycolysis. The word glycolysis originates from the Latin glyco (sugar) and lysis (breakdown). Glycolysis serves two main intracellular functions: generating ATP and generating...
