Knockdown of Neat1 improves muscle growth in vivo.a The injection scheme for LV3-shNeat1 or LV3-shNC particles into the right or left hindlimb muscles of C57 mice. The injection was given every one week for one month. b qPCR results showing that Neat1 expression was reduced after LV3-shNeat1 particle injection, while the mRNA expression of Myog, Myhc, α-actin, and Tnni2 was significantly increased after LV3-shNeat1 particle injection. c Western blot analysis showing that the protein expression of Myog, Myhc, α-actin, and Tnni2 was increased after LV3-shNeat1 particle injection. The protein levels of these genes were quantified using ImageJ software. d Representative photograph of the three muscles from the right or left hindlimbs showing that the volume of the Qu, TA, and Gas muscles of the right hindlimb were larger than those of the left hindlimb. e Quantification of the weight of three muscles from the right or left hindlimbs of 12 injected mice showing that the weight of the Qu, TA, and Gas muscles of the right hindlimb were higher than those of the left hindlimb. f Representative photograph of myosin immunofluorescence staining in Qu, TA, and Gas muscles from the right or left hindlimb following injection with LV3-shNeat1 or LV3-shNC particles. Compared with LV3-shNC particle injection, LV3-shNeat1 particle injection increased the average cross-sectional areas of the indicated muscles. The fiber sizes of the Qu, TA, and Gas muscles were quantified using ImageJ. Relative RNA and protein levels were normalized to those of Gapdh.

Supplementary information

Troponin I fast skeletal muscle also known as TNNI2 is a protein involved in muscle contraction. It weighs around 21.2 kDa and is mainly expressed in fast-twitch skeletal muscle. TNNI2 acts by inhibiting actomyosin ATPase activity meaning it helps prevent muscle contraction until it receives a signal to contract. It binds to actin and plays a regulatory role in the muscle contraction process.
Biological function summary

Troponin I fast skeletal muscle interacts within the troponin complex which includes Troponin T and Troponin C. Located on the thin filament of the muscle fiber this complex modulates the contraction of striated muscle by controlling calcium binding. When calcium binds to Troponin C it induces a conformational change that displaces TNNI2 from actin allowing for muscle contraction to occur.

Pathways

Troponin I fast skeletal muscle has essential functions in the calcium modulation pathways specific to muscle contraction. It plays an important role in the regulation of muscle contraction by interacting with calcium ions and other proteins such as tropomyosin. As part of the excitation-contraction coupling pathway TNNI2 helps ensure the proper contraction of muscles in response to neural stimulation. Additionally its role in these pathways involves specific interactions with proteins like Troponin C and Troponin T which are necessary for functional muscle contraction.

Abnormalities in Troponin I fast skeletal muscle can lead to muscle-related conditions such as nemaline myopathy and distal arthrogryposis. These disorders affect muscle structure and function leading to muscle weakness or deformities. Mutations in TNNI2 may result in improper interaction with other sarcomeric proteins such as tropomyosin disrupting normal muscle contraction and leading to the mentioned diseases. Understanding the role of TNNI2 in these disorders can aid in the development of diagnostic and therapeutic strategies.
