Insights

MicroRNA-183 (miR-183) injection shows promise in treating systemic lupus erythematosus (SLE). This study found that miR-183 reduced disease markers and extended lifespan in a mouse model of SLE.

Area of Science:

  • Immunology
  • Molecular Biology
  • Genetics

Background:

  • Systemic lupus erythematosus (SLE) is a complex autoimmune disease with significant morbidity.
  • MicroRNAs (miRNAs) are implicated in the pathogenesis of various human diseases, including SLE.
  • Understanding miRNA roles offers potential for novel therapeutic strategies in SLE.

Purpose of the Study:

  • To investigate the therapeutic potential of miR-183 injection in a mouse model of SLE.
  • To assess the impact of miR-183 on disease progression markers and survival.

Main Methods:

  • Utilized the MRL/lpr mouse model for spontaneous SLE development.
  • Administered miR-183 via intraperitoneal injection.
  • Quantified miR-183 and mTOR mRNA expression using real-time PCR.
  • Monitored lifespan, anti-dsDNA antibodies, urinary albumin, blood urea nitrogen (BUN), and T cell populations (Tregs and Th17).

Main Results:

  • miR-183 injection significantly reduced anti-dsDNA antibody and immune complex levels.
  • Restored the balance of regulatory T (Tregs) and T helper 17 (Th17) cell populations.
  • Prolonged the survival of MRL/lpr mice.
  • miR-183 expression correlated with mTOR mRNA levels.

Conclusions:

  • miR-183 injection demonstrates therapeutic efficacy in mitigating SLE progression.
  • This miRNA-based therapy may offer a novel approach to managing SLE.
  • Further research into miR-183 as a treatment for SLE is warranted.

Transcription Attenuation in Prokaryotes02:42

Transcription Attenuation in Prokaryotes

Transcriptional attenuation occurs when RNA transcription is prematurely terminated due to the formation of a terminator mRNA hairpin structure.  Bacteria use these hairpins to regulate the transcription process and control the synthesis of several amino acids including histidine, lysine, threonine, and phenylalanine. Transcription attenuation takes place in the non-coding regions of mRNA.
There are several different mechanisms used to attenuate transcription. In ribosome mediated...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.
The ATR process begins by directing a beam...

Burn Injuries01:22

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Drug Delivery: Overview01:16

Drug Delivery: Overview

The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...
