MicroRNAs01:22

MicroRNAs

24.3K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Sustainable Development

15.2K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Development of the Lymphatic System01:15

Development of the Lymphatic System

2.1K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Language Development

921
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Development of Immunocompetence01:22

Development of Immunocompetence

927
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Area of Science:

  • Developmental Biology
  • Molecular Biology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are small RNA molecules that regulate gene expression.
  • miRNAs are vital for the development of most organisms.
  • Numerous miRNAs are expressed in the vertebrate retina during development and maturation.

Purpose of the Study:

  • To investigate the roles of microRNAs in vertebrate retinal development.
  • To understand the impact of miRNA dysregulation on developmental transitions.

Main Methods:

  • Analysis of miRNA expression in developing and mature vertebrate retinas.
  • Studying the effects of miRNA loss-of-function through knockdowns or global perturbations (e.g., Dicer deletion).

Main Results:

  • miRNAs regulate diverse messenger RNA targets, influencing multiple developmental processes.
  • Developmental transitions between cell states are particularly sensitive to miRNA loss.
  • Specific miRNA functions in retinal development are still largely undocumented.

Conclusions:

  • While miRNAs are known to be critical for development, their precise functions in the vertebrate retina are still in the early stages of discovery.
  • Further research is needed to elucidate the full spectrum of cellular functions controlled by miRNAs during retinal development.
