A point mutation of integrin beta 1 subunit blocks binding of alpha 5 beta 1 to fibronectin and invasin but not recruitment to adhesion plaques. [PDF]

open access: yes, 1992
A point mutation in a highly conserved region of the beta 1 subunit, Asp130 to Ala (D130A) substitution, abrogates the Arg-Gly-Asp (RGD)-dependent binding of alpha 5 beta 1 to fibronectin (FN) without disrupting gross structure or heterodimer assembly ...

Cellular Snowballing: Cell Adhesion and Migration Drive the Self‐Assembly of Cell‐Microgel Biohybrid Spheroids

open access: yesAdvanced Science, EarlyView.
A new class of biohybrid spheroids is engineered through the self‐assembly of adherent cells and extracellular matrix‐mimetic hydrogel microparticles (microgels). By mimicking a snowballing effect, this approach enables scalable formation of porous, millimeter‐scale spheroids with enhanced cell viability and molecular diffusion.

Rabl's model of the interphase chromosome arrangement tested in Chinise hamster cells by premature chromosome condensation and laser-UV-microbeam experiments [PDF]

open access: yes, 1982
In 1885 Carl Rabl published his theory on the internal structure of the interphase nucleus. We have tested two predictions of this theory in fibroblasts grown in vitro from a female Chinese hamster, namely (1) the Rabl-orientation of interphase ...

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

open access: yesAdvanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Stereoselective Biotransformation: Transfer of Learning to Advance Drug Metabolism and Biocatalysis

open access: yesAngewandte Chemie, EarlyView.
Understanding stereoselective biotransformations has implications for predicting drug disposition and response and may also inspire novel biocatalytic and biomimetic strategies to address challenges in metabolite and API synthesis. ABSTRACT Chirality is an important determinant of drug action, as enantiomers can exhibit markedly different ...

Synthetic LXR agonists increase LDL in CETP species

open access: yesJournal of Lipid Research, 2005
Liver X receptor (LXR) nuclear receptors regulate the expression of genes involved in whole body cholesterol trafficking, including absorption, excretion, catabolism, and cellular efflux, and possess both anti-inflammatory and antidiabetic actions ...

Immunocytochemical localization of chromatin regions UV-microirradiated in S phase or anaphase : Evidence for a territorial organization of chromosomes during cell cycle of cultured Chinese hamster cells [PDF]

open access: yes, 1983
Chinese hamster cells (M3-1 line) in S phase were laser-UV-microirradiated (λ, 257 nm) at a small site of the nucleus. Cells were fixed either immediately thereafter or in subsequent stages of the cell cycle, including prophase and metaphase.

Sulfakinin Signaling Sense Circulating Fructose and Suppresses Food Consumption via Insulin‐Like Peptide in Bactrocera Dorsalis

open access: yesAdvanced Science, EarlyView.
This study discovered a new pathway that tells fruit flies when to stop eating. It found that rising blood sugar (fructose) is detected by a sensor called GR43a. This triggers a chain reaction involving the satiety signal sulfakinin and its receptor, ultimately activating a final satiety signal, ILP5.

Electron microscopic study of intestinal fat absorption in vitro from mixed micelles containing linolenic acid, monoolein, and bile salt

open access: yesJournal of Lipid Research, 1966
Sacs and segments of everted hamster gut were incubated in vitro in solutions of mixed micelles (containing taurodeoxycholate, monoolein, and linolenic acid) for various periods and at different temperatures. The appearance of electron micrographs of the

Quantitative Mass Spectrometry‐Based Biodistribution of Monoclonal Antibodies: An Alternative to Radio‐Biodistribution

open access: yesAdvanced Science, EarlyView.
Monoclonal antibodies are powerful anticancer therapeutics targeting tumor‐associated antigens. Mass spectrometry enables precise and accurate quantification of mAbs in tumor plasma and healthy organs. Unlike ligand binding assay and radioactivity, mass spectrometry does not suffer from matrix effects and labelling artefacts while facilitating method ...
