概括
左侧声麻可能源于喉肌肉的遗传差异,而不仅仅是神经长度. 这项研究在老鼠的左侧和右侧内在喉肌肉之间发现了不同的基因表达模式,这表明这种横向性的遗传基础.
科学领域:
- 分子生物学分子生物学
- 神经科学是一个神经科学.
- 遗传学 是一个遗传学.
背景情况:
- 声麻不成比例地影响左侧,通常归因于重复的喉神经长度.
- 这项研究调查了可能导致左侧声麻的潜在基因因素.
- 探索内在喉肌肉 (ILM) 中的基因表达可能会揭示这种观察到的横向性的机制.
研究的目的:
- 研究左侧和右侧之间的内在喉肌肉 (ILM) 中潜在的不对称基因表达.
- 鉴定特定的基因和途径,这些基因和途径有助于ILM神经肌肉功能和再内核化潜力的左右差异.
主要方法:
- 进行RNA测序 (RNA-Seq),对来自不同年龄和性别的老鼠的左侧和右侧ILM进行测序 (后部状腺,侧部状腺,中部状腺).
- 综合生物信息学分析,包括基因本体学和KEGG通路丰富,用于比较转录组资料.
主要成果:
- 在左和右ILM之间确定了774个差异表达基因 (DEG),具有显著的年龄,性别和肌肉特异性变异.
- 丰富分析突出了参与神经元和肌肉生理学,免疫反应和激素控制的基因,表明左右不对称.
结论:
- 生物信息学分析证实左侧和右侧内在喉肌肉之间存在不同的基因表达特征.
- 这项初步研究确定了潜在的遗传标,这可能解释了内在喉肌肉功能中观察到的横向性.
- 研究结果表明,ILM的遗传不对称性可能导致左侧声麻的发病率更高.

Muscles for Facial Expressions
2.1K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Larynx
1.6K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Cranial Nerves: Types Part II
2.5K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
