Figure Lengend Snippet: Silencing Slit1 in murine myoblasts leads to pre-mature differentiation. A-A”’. Control siRNA transfected C2C12 mouse myoblasts show myotube formation by Day (D) 5 of differentiation protocol. B-B”’. siRNA-mediated downregulation of Slit1 in C2C12 cells leads to the formation of myofiber like structures, highlighted by black arrows (B’), quite premtaurely i.e. on second day (D2) of differentiation. C. Representative immunoblots showing levels of SLIT1 and ≥-ACTIN, at DO, D2, D5, and D7 of myoblast differentiation, in cell lysates of C2C12 cells transfected with control or $/it1 siRNA. D-E. Bar graphs representing densitometric analyses of SLIT1 expression at DO and D2 (D), and at DO, D5, and D7 (E) of differentiation, in control versus Slit1 siRNA transfected C2C12 lysates as represented in the corresponding immunoblots (C). F-1. Representative western blots (F) and their densitometric quantitation (G-J), depicting expression of Myosin (F-H) and Cleaved Caspase 3 (CC-3) (F, 1-J) at indicated day (D) of myogenic differentiation in lysates from C2C12 cells transfected with control or Slit1 siRNA. For densitometric quantification, SLIT1, Myosin and CC-3 expression was normalized to corresponding ≥-ACTIN levels at each differentiation day for both (control and $/it1) siRNA transfections. Expression of gene of interest, normalized to reference gene values at indicated days of differentiation, were in turn normalised to similarly normalized DO values of the respective siRNA transfection. The graphical data are represented as means +SD and were subjected to multiple unpaired T-tests. ns=non-significant.
Article Snippet: C2C12 mouse myoblast cells (American Type Culture Collection-ATCC; Cat# CRL-1722) were cultured and maintained in complete medium [CM = DMEM (Thermo Fisher Scientific; GIBCO, Cat# 11995065) + 10% fetal bovine serum (FBS, Thermo Fisher Scientific; GIBCO, Cat# 10270106) + 1% Penicillin-Streptomycin (Thermo Fisher Scientific; GIBCO, Cat# 15240062)], according to ATCC recommendations.
