IGFBP6 Modulates Proteostasis by Activating ATF4 Targets and Reducing ER Retrotranslocon Expression.

Reduced expression of the IGFBP6 protein leads to an increase in the metastatic potential of breast cancer (BC) cells. The level of protein synthesis in tumor cells is increased, leading to a compensatory adjustment of proteostasis. One of the tools used to study proteostasis is protein toxins of the RIP-II family, which irreversibly inactivate ribosomes (particularly, viscumin).

Intracranial voltage profiles from untangled human deep sources reveal multisource composition and source allocation bias.

Intracranial potentials are used as functional biomarkers of neural networks. As potentials spread away from the source populations, they become mixed in the recordings. In humans, interindividual differences in the gyral architecture of the cortex pose an additional challenge, as functional areas vary in location and extent.

IGFBP6 regulates extracellular vesicles formation via cholesterol abundance in MDA-MB-231 cells.

Breast cancer recurrence is associated with the growth of disseminated cancer cells that separate from the primary tumor before surgical treatment and hormonal therapy and form a metastatic niche in distant organs. We previously demonstrated that IGFBP6 expression is associated with the risk of early relapse of luminal breast cancer. Knockdown of IGFBP6 in MDA-MB-231 breast cancer cells increased their invasiveness, proliferation, and metastatic potential.

α-Latrotoxin Tetramers Spontaneously Form Two-Dimensional Crystals in Solution and Coordinated Multi-Pore Assemblies in Biological Membranes.

α-Latrotoxin (α-LTX) was found to form two-dimensional (2D) monolayer arrays in solution at relatively low concentrations (0.1 mg/mL), with the toxin tetramer constituting a unit cell. The crystals were imaged using cryogenic electron microscopy (cryoEM), and image analysis yielded a ~12 Å projection map.

[Burden and management of severe asthma in Russia: results from international observational study].

Aim: To assess clinical and demographic characteristics of severe asthma (SA) patients and their management in Russian Federation.

Materials And Methods: This publication provides data for Russian part of population of the international observational study. In Phase I, retrospective analysis of medical records of patients with SA was performed with assessment of clinical and demographic data, medical history, comorbidities, treatment approaches and healthcare utilization.
