まとめ
MTHFR 677C> T遺伝子の変異体と高濃度のホモシステインは,男性と女性の両方で不良な妊娠結果と関連しています. しかし,MTHFR 677C>Tポリモルフィズム
科学分野:
- 遺伝学
- 生殖生物学
- 生物化学
背景:
- MTHFR 677C> Tポリモルフィズムは,女性の不良妊娠結果 (APO) と関連しています.
- 男性への影響に関する研究は限られている.
- 性別特有のリスクを理解することは 生殖健康にとって極めて重要です
研究 の 目的:
- MTHFR 677C> Tポリモルフィズムとホモシステイン (Hcy) レベルが,男性と女性の両方の不良妊娠結果と関連していることを調査する.
- 性別別別別の差異を調査する
主な方法:
- 1265人の成人のMTHFR677C> T多形性 (662人の染色体異常,137人の口唇裂け,133人の生化学妊娠,339人の対照群) の遺伝子タイプ化.
- すべての参加者のホモシステイン (Hcy) レベルを分析した.
- 性別によって層分かれ,症例群と対照群の遺伝子型頻度とHcyレベルを比較.
主要な成果:
- Hcyの値上昇は,染色体異常 (CA),口唇裂け (CLP),および生化学妊娠 (BP) のリスク因子である.
- MTHFR 677C>Tポリモルフィズムは女性ではCA,BP,CLPの危険因子ですが,男性ではCAとBPのみです.
- TT遺伝子型を持つ個人はHcy値が最も高かった. 男性は女性よりもHcy濃度と高血糖血症の発生率が著しく高かった.
結論:
- MTHFR 677C>Tポリモルフィズムでは,胎児のCLPには性別によるリスクがあり,BPとCAには性別によるリスクはありません.
- 高濃度のHcyは,BP,CLP,CAの性別に関係ないリスク因子です.
- MTHFR677TT遺伝子型は,より高いHcy濃度と関連しており,Hcy濃度と高血糖血症の有意な性別差が観察されています.

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

Teratogenicity
2.7K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Meiosis vs. Mitosis
58.1K
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
