Gonadal and Placental Hormones

3.2K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

Inertial Frames of Reference01:03

Inertial Frames of Reference

8.8K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference01:27

Non-inertial Frames of Reference

7.2K
A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

Chemical Shift: Internal References and Solvent Effects

1.4K
In an NMR sample, precise measurement of the absolute absorption frequencies of nuclei is difficult. A standard internal reference compound is added, and the frequency difference between the reference signal and sample signals is measured.
The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...

Gene Families01:57

Gene Families

10.0K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Summary

Finding stable reference genes is crucial for accurate gene expression studies in developing mouse gonads. Peptidylprolyl isomerase A (Ppia) and polymerase (RNA) II (DNA directed) polypeptide A (Polr2a) demonstrated the most consistent expression across different periods and genders.

Area of Science:

  • Developmental Biology
  • Molecular Biology
  • Genetics

Background:

  • Accurate gene expression analysis, particularly using quantitative PCR (qPCR), relies on the selection of stable reference genes.
  • Identifying reliable reference genes is critical for studying gene expression in developing mouse gonads, a complex biological process.

Purpose of the Study:

  • To systematically evaluate the stability of 15 candidate reference genes in developing mouse gonads.
  • To identify the most suitable reference genes for accurate gene expression analysis across different developmental stages and genders.

Main Methods:

  • Utilized multiple algorithms to assess the expression stability of 15 candidate reference genes.
  • Analyzed gene expression fluctuations based on developmental period and gender in mouse gonads.

Main Results:

  • Significant variations in gene expression were observed for most candidate genes, influenced by developmental timing and gender.
  • Peptidylprolyl isomerase A (Ppia) and polymerase (RNA) II (DNA directed) polypeptide A (Polr2a) emerged as the most stable reference genes over a broad analysis period.
  • Rankings of stable reference genes were provided, specific to developmental period and/or gender.

Conclusions:

  • The choice of reference gene is critical and must be validated for specific experimental conditions in developing mouse gonads.
  • Ppia and Polr2a are recommended as reliable reference genes for broad applications, while period/gender-specific options offer enhanced precision.
