- 分子生物学は分子生物学である.
- バイオケミストリー バイオケミストリー
背景:
- 衰弱したヒトの心臓は,カルシウム処理が損なわれ,サルコプラズマ網膜のCa2+ATPアゼ (SERCA2a) 活性が低下しています.
- フォスフォランバンは通常,SERCA2aを阻害し,心不全における収縮機能障害に貢献します.
研究 の 目的:
- アンチセンセスフォスフォルバン (asPL) のアデノウイルスの遺伝子転送によるSERCA2aに対するフォスフォルバン抑制効果の減少が,人間の心筋不全における収縮機能を改善できるかどうかを調査する.
主な方法:
- 心不全と心不全のない心臓のヒト心筋細胞は,asPL,SERCA2a,またはレポーター遺伝子をコードするアデノウイルスに感染しました.
- フォスフォランバン発現レベルと心筋細胞の収縮/リラックス速度は,感染後に測定されました.
主要な成果:
- Ad.asPLによるアデノウイルスの遺伝子転送は,フォスフォランバン発現を著しく低下させた.
- これは,Ad.SERCA2a治療に匹敵する,失敗した心筋細胞の収縮とリラックス速度を増加させた.

Gene Therapy
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be inserted. The...
Types of Genetic Transfer Between Organisms
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.
Gene Conversion
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

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.
