| Myotubularin and PtdIns3P remodel the sarcoplasmic reticulum in muscle in vivo

The sarcoplasmic reticulum (SR) is a specialized form of endoplasmic reticulum (ER) in skeletal muscle
and is essential for calcium homeostasis. The mechanisms involved in SR
remodeling and maintenance of SR subdomains are elusive. In this study, we identified
myotubularin (MTM1), a phosphatase mutated in X-linked centronuclear myopathy
(XLCNM), as a key regulator of phosphoinositide-3-monophosphate (PtdIns3P) levels at the
SR. Mtm1 deficient mouse muscles and myoblasts from XLCNM patients exhibit abnormal
SR/ER networks. In vivo modulation of MTM1 enzymatic activity in muscle using ectopic
expression of wild-type or a dead-phosphatase MTM1 protein leads to differential SR
remodeling. Active MTM1 is associated to flat membrane stacks, while dead-phosphatase
MTM1 mutant promotes highly curved cubic membranes originating from the SR and
enriched in PtdIns3P. Moreover, expression of the PtdIns3P binding module 2XFYVE also
modified the SR shape at triads. Our findings, supported by the parallel analysis of the Mtm1-
null mouse and in vivo study, reveal a direct function of MTM1 enzymatic activity in SR
remodeling and a key role for its substrate PtdIns3P in promoting SR membrane curvature in
skeletal muscle. We propose that alteration in SR remodeling is a primary cause of X-linked
centronuclear myopathy. The tight regulation of PtdIns3P on specific membrane subdomains
may be a general mechanism to control membrane curvature.

| Hamiltonian formulation of surfaces with constant Gaussian curvature
Miguel Trejo, Martine Ben Amar, Martin Michael Müller |
Dirac's method for constrained Hamiltonian systems is used to describe surfaces of constant Gaussian curvature. A geometrical free energy, for which these surfaces are equilibrium states, is introduced and interpreted as an action. An equilibrium surface can then be generated by the evolution of a closed space curve.
Since the underlying action depends on second derivatives, the velocity of the curve and its conjugate momentum must be included in the set of phase space variables. Furthermore, the action is linear in the acceleration of the curve and possesses a local symmetry---reparametrization invariance---which implies primary constraints in the canonical formalism. These constraints are incorporated into the Hamiltonian through Lagrange multiplier functions, that are identified as the components of the acceleration of the curve. The formulation leads to four first order partial differential equations, one for each canonical variable.
With the appropriate choice of parametrization only one of these equations has to be solved to obtain the surface which is swept out by the evolving space curve. To illustrate the formalism, several evolutions of pseudospherical surfaces are discussed.

| Conical Defects in Growing Sheets
Martin Michael Müller, Martine Ben Amar, Jemal Guven |
A growing or shrinking disc will adopt a conical shape, its intrinsic geometry characterized by a surplus angle φe at the apex. If growth is slow, the cone will find its equilibrium. Whereas this is trivial if φe≤0, the disc can fold into one of a discrete infinite number of states if φe is positive. We construct these states in the regime where bending dominates, determine their energies and how stress is distributed in them. For each state a critical value of φe is identified beyond which the cone touches itself. Before this occurs, all states are stable; the ground state has twofold symmetry.

| How to determine local elastic properties of lipid bilayer membranes
from atomic-force-microscope measurements: A theoretical analysis
Davood Norouzi, Martin Michael Müller, Markus Deserno |
Measurements with an atomic force microscope (AFM) offer a direct way to
probe elastic properties of lipid bilayer membranes locally: provided
the underlying stress-strain relation is known, material parameters such as
surface tension or bending rigidity may be deduced.
In a recent experiment a pore-spanning membrane was poked with an AFM tip,
yielding a linear behavior of the force-indentation curves. A theoretical
model for this case is presented here which describes these curves in the
framework of Helfrich theory. The linear behavior of the measurements is
reproduced if one neglects the influence of adhesion between tip and membrane.
Including it via an adhesion balance changes the situation significantly:
force-distance curves cease to be linear, hysteresis and nonzero detachment
forces can show up. The characteristics of this rich scenario are discussed
in detail in this article.
