Multiplex Chemical Imaging Based on Broadband Stimulated Raman Scattering Microscopy

We present a protocol to acquire chemical images with broadband stimulated Raman scattering (SRS) microscopy. Based on an SRS microscope that operates with differential multichannel-lock-in detection, the protocol describes the sample preparation, adjustment of the SRS apparatus, and chemometrics to disentangle different constituents of chemically heterogeneous samples. Our protocol describes…

Proscillaridin A induces mitochondrial damage and autophagy in pancreatic cancer and reduces the stability of SMAD4 in Panc-1 cells – Hou

Introduction Pancreatic cancer (PC) is one of the most aggressive and lethal cancers (1). Previous studies have shown that aging, environmental and behavioral changes are more closely related to the dramatic increase in the incidence of PC worldwide than genetic factors (2–5). A position paper published by the European Federation…

Dietary selection of metabolically distinct microorganisms drives hydrogen metabolism in ruminants

Volatile fatty acid production and absorption is modulated by diet Animals were adapted to a starch-rich diet by gradually increasing dietary concentrate content from 50 to 90% over the three 100-d experimental periods (Fig. 1A). With both diets, rumen structure and epithelial morphology were robust and rumen pH remained above 6.0…

Simplified, High-throughput Analysis of Single-cell Contractility using Micropatterned Elastomers

Cell generated mechanical forces are essential to proper function in various organs throughout the body. Plus the intestines bladder, heart, and others. These organs must generate stable patterns of cell contraction and relaxation, to maintain the internal hemostatic state. Abnormal smooth muscle cell contraction can lead to the onset of…

Visualizing Shifts on Neuron-Glia Circuit with the Calcium Imaging Technique

Cell calcium imaging is a versatile methodology to study dynamic signaling of individual cells, on mixed populations in culture or even on awakened animals, based on the expression of calcium-permeable channels/receptors that gives unique functional signatures. The overall goal of this procedure is to monitor changes in cytosolic calcium concentrations…

Profiling and functional characterization of maternal mRNA translation during mouse maternal-to-zygotic transition

INTRODUCTION Mammalian life starts with the fusion of two terminally differentiated gametes, sperm and oocyte, resulting in a totipotent zygote. After going through preimplantation development, the zygote reaches blastocyst before implantation. The two most important events taking place during preimplantation development are zygotic genome activation (ZGA) and the first cell…

p57 Suppresses the Pluripotency and Proliferation of Mouse Embryonic Stem Cells by Positively Regulating p53 Activation

Embryonic stem cells (ESCs) are pluripotent stem cells that have indefinite self-renewal capacities under appropriate culture conditions in vitro. The pluripotency maintenance and proliferation of these cells are delicately governed by the concert effect of a complex transcriptional regulatory network. Herein, we discovered that p57Kip2 (p57), a cyclin-dependent kinase inhibitor…

High tumor mutation burden and DNA repair gene mutations

Introduction Anaplastic lymphoma kinase (ALK)‑fusion genes represent a small but important part of oncogenic driver mutations in NSCLC, accounting for approximately 3%‑7% of all cases worldwide.1,2 Small molecule tyrosine kinase inhibitors (TKIs) are the standard therapy for ALK-rearranged NSCLC. Crizotinib, a first-generation TKI, is the most widely used targeted drug…

Bacterial endosymbionts protect beneficial soil fungus from nematode attack

A healthy soil nourishes plants and animals, purifies water and air, and promotes sustainable agriculture. Characteristic for highly complex and competitive soil ecosystems are the frequent and direct interactions between all soil-dwelling microorganisms, animals, and plants (1, 2), all of which need to be provided with minerals and carbon sources….

Genome-wide synthetic lethal screen unveils novel CAIX-NFS1/xCT axis as a targetable vulnerability in hypoxic solid tumors

Abstract The metabolic mechanisms involved in the survival of tumor cells within the hypoxic niche remain unclear. We carried out a synthetic lethal CRISPR screen to identify survival mechanisms governed by the tumor hypoxia–induced pH regulator carbonic anhydrase IX (CAIX). We identified a redox homeostasis network containing the iron-sulfur cluster…
