The invention discloses an LMNA gene knocked-out cell line. The cell line is a 293T cell line or a HePG2 tumor cell line. Cells to be knocked out are transfected by plasmid vectors constructed by twopairs of gRNA as shown in SEQ ID NO. 1-4 or two pairs of gRNA as shown in SEQ ID NO. 7-10 on the basis of a crispr-cas9 technology, and then are subjected to resistance screening to obtain the cell line. The LMNA gene knocked-out cell line can be used for intervention drug screening cell models for diseases such as dilated cardiomyopathy, fat metabolic disorder syndrome and premature aging syndromes.

Cardiomyopathy may be treated by distributing space-occupying agent within the myocardium in a pattern about one or more chambers of the heart, such that the space-modifying agent integrates into and thickens at least part of the cardiac wall about the chamber so as globally to reduce wall stress and stabilize or even reduce chamber size. Some patterns also cause a beneficial global reshaping of the chamber. These changes occur quickly and are sustainable, and have a rapid and sustainable therapeutic effect on cardiac function. Over time the relief of wall stress reduces oxygen consumption and promotes healing. Moreover, various long-term therapeutic effects may be realized depending on the properties of the space-occupying agent, including combinations with other therapeutic materials. Specific cardiac conditions treatable by these systems and methods include, for example, dilated cardiomyopathy (with or without overt aneurismal formations), congestive heart failure, and ventricular arrhythmias. Patterns of distribution of space-occupying agent within the myocardium for global resizing may also be used or augmented to treat localized conditions such as myocardial infarctions, overt aneurysm of the ventricular wall as typically forms in response to large transmural myocardial infarctions, and mitral regurgitation due to a noncompliant mitral valve. These techniques may also be used to treat localized conditions that may not yet have progressed to cardiomyopathy.
