Exercise and Cardiovascular Response01:20

Exercise and Cardiovascular Response

6.4K
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

MicroRNAs01:22

MicroRNAs

4.4K
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 the pre-miRNA...

Formation of Muscle Fibers from Myoblasts01:13

Formation of Muscle Fibers from Myoblasts

7.5K
De novo myogenesis, or the formation of muscle fibers, begins during the early embryonic stages. The skeletal muscle is formed from somites– blocks of embryonic cell layers. The somites are further divided into dermatomes, myotomes, sclerotomes, and syndetomes. Among these, the myotomes give rise to muscle fibers.
Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription...

Cellular Adaptation II: Hypertrophy01:26

Cellular Adaptation II: Hypertrophy

5
Hypertrophy is the increase in the size of individual cells, resulting in the enlargement of a tissue or organ. Unlike hyperplasia, which involves an increase in cell number, hypertrophy is characterized by an increase in cell volume. This process often occurs in response to higher functional demand or hormonal stimulation, leading to the production of more structural proteins and organelles, thereby enhancing the cells' work capacity.There are two primary types of hypertrophy:...

Area of Science:

  • Molecular Biology
  • Exercise Physiology
  • Biochemistry

Background:

  • MicroRNAs (miRNAs) are endogenous noncoding RNAs regulating gene expression post-transcriptionally.
  • miRNAs are crucial in biological processes like proliferation, differentiation, and metabolism.
  • Circulating miRNAs are stable and detectable in bodily fluids.

Purpose of the Study:

  • To review and summarize recent findings on circulating miRNAs in response to exercise.
  • To discuss the role of circulating miRNAs in exercise-induced adaptations.
  • To explore the potential of circulating miRNAs as therapeutic targets.

Main Methods:

  • Literature review of studies investigating circulating miRNAs and exercise.
  • Analysis of data on miRNA expression changes following acute and chronic exercise.
  • Synthesis of current knowledge on miRNA regulation in exercise physiology.

Main Results:

  • Exercise, both acute and chronic, significantly impacts circulating miRNA profiles.
  • Specific circulating miRNAs show altered expression levels in response to different exercise stimuli.
  • These changes suggest miRNAs are involved in the physiological adaptations to exercise.

Conclusions:

  • Circulating miRNAs are responsive to exercise and reflect physiological adaptations.
  • Understanding these responses can lead to novel biomarkers for exercise capacity.
  • Targeting circulating miRNAs may offer therapeutic strategies for conditions like heart failure.
