Translational control by DHX36 binding to 5′UTR G-quadruplex is essential for muscle stem-cell regenerative functions

Image
Activation-induced DHX36 is required for muscle formationTo dissect whether DHX36 functions in SCs and muscle regeneration, we first examined Dhx36 expression dynamics during SC myogenic progression. Quiescent SCs were isolated by fluorescence-activated cell sorting (FACS) from Pax7-nGFP mice25, either fixed in situ by 0.5% paraformaldehyde (PFA) prior to muscle digestion (SCT0) or from muscles digested [...] Published August 18, 2021 at 07:58PM.

A SAS macro for estimating direct adjusted survival functions for time-to-event data with or without left truncation

Image
Detailed formulae to estimate direct adjusted survival functions and their variances are published [6]. Constructing confidence bands and computing simultaneous p values is described by Wang and Zhang [8]. For left-truncated data,the risk-set needs to be appropriately adjusted at estimating time individually.Improvements in computational performance%adjsurvlt() has several computational enhancements.

GPX4 deficiency results in HSPCs ferroptosis in vitroHSCs rapidly proliferate and differentiate to generate single-cell colonies when they are cultured in vitro. For determination of whether GPX4 is essential for HSC function, individual long-term HSCs (LT-HSCs) from wild-type mice were sorted and treated with RSL3, a widely used GPX4 inhibitor.

Upfront intensive chemo-immunotherapy with autograft in 199 adult mantle cell lymphoma patients: prolonged survival and cure potentiality at long term

Image
Mantle cell lymphoma (MCL) is a rare disease with an aggressive clinical course in most patients. This resulted in a median survival of MCL of only 3–5 years [1]. Intensive first-line chemo-immunotherapy with autograft has improved the clinical outcome of MCL. However, the clinical course remains heterogeneous and can only be partially predicted with internationally [...] Published July 06, 2021 at 07:38PM.

Osteolectin+ stromal cells: Mechanical stimulation improves bone regeneration and supports bacterial clearance after fracture

Image
In a study recently published in Nature, Shen and colleagues characterized a peri-arteriolar niche in the bone marrow with highly proliferative, short-lived, leptin receptor- and osteolectin (Oln) positive stromal cells, which improved bone regeneration and supported bacterial clearance after fracture. By proving that maintenance of these cells critically required mechanical stimulation, which in turn was [...] Published July 06, 2021 at 07:08PM.
