Maximal fluctuations of confined actomyosin gels: dynamics of the cell nucleus

open access: yes, 2018
We investigate the effect of stress fluctuations on the stochastic dynamics of an inclusion embedded in a viscous gel. We show that, in non-equilibrium systems, stress fluctuations give rise to an effective attraction towards the boundaries of the ...

Induction of chromosome shattering by ultraviolet light and caffeine [PDF]

open access: yes, 1981
Synchronized and asynchronously growing cells of a V79 sub-line of the Chinese hamster were either partial-cell irradiation (λ, 254 nm) or laser-UV-microirradiated (λ, 257 nm).

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

2D Mapping of pathological nuclei [PDF]

open access: yes, 2010
The dynamics of genome regions are associated to the functional or dysfunctional behaviour of the human cell. In order to study these dynamics it is necessary to remove perturbations coming from movement and deformation of the nucleus, i.e. the container

Connections of the corpus cerebelli in the green sunfish and the common goldfish [PDF]

open access: yes, 1988
Examination of the connections of the corpus cerebelli in one perciform (Lepomis cyanellus) and one cypriniform teleost (Carassius auratus) reveal that ipsilateral afferent connections in both species arise from an anterior group of nuclei in the ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Troponin T3 regulates nuclear localization of the calcium channel Cavβ1a subunit in skeletal muscle [PDF]

open access: yes, 2015
The voltage-gated calcium channel (Cav) β1a subunit (Cavβ1a) plays an important role in excitation-contraction coupling (ECC), a process in the myoplasm that leads to muscle-force generation. Recently, we discovered that the Cavβ1a subunit travels to the

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

An Unusual Melanocytic Nevus of Conjunctiva : Balloon Cell Nevus [PDF]

open access: yes, 2011
Melanocytic nevi are one of the most common benign tumors of the conjunctiva. The balloon cell nevus is a rare and unusual variant of nevus of melanocytic origin, in which more than 50% of the tumor is composed of large polygonal cells with small nucleus
