Cystatin A promotes the antitumor activity of T helper type 1 cells and dendritic cells in murine models of pancreatic cancer

Molecular Oncology, Volume 19, Issue 5, Page 1452-1470, May 2025.
Pancreatic ductal adenocarcinoma (PDAC) is a disease with very poor prognosis due to therapeutic limitations. We investigated the antitumor effects of cystatin A (CSTA) in PDAC murine models. We are first to confirm that CSTA enhances T helper type 1‐mediated antitumor effects through promotion of dendritic cells and M1 macrophage activity. CSTA can be

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

Molecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Resonance fluorescence from an asymmetric quantum dot dressed by a bichromatic electromagnetic field [PDF]

Phys. Rev. A 95, 013834 (2017), 2016
We present the theory of resonance fluorescence from an asymmetric quantum dot driven by a two-component electromagnetic field with two different frequencies, polarizations and amplitudes (bichromatic field) in the regime of strong light-matter coupling.

Pengukuran Perubahan Sudut Polarisasi oleh Fluoresensi pada Sampel Minyak Zaitun [PDF]

, 2016
The aim of this research is to show how the quality difference of cooking oil affect polarization angle changes of fluorescence. The fluorescence could be usefull to identify quality of matter according to colour changes.

Understanding and measuring mechanical signals in the tumor stroma

FEBS Open Bio, EarlyView.
This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...

NPC1 promotes the progression of hepatocellular carcinoma by mediating the accumulation of neutrophils into the tumor microenvironment

FEBS Open Bio, Volume 15, Issue 4, Page 661-673, April 2025.
Compared to normal tissues, NPC1 expression is significantly elevated in hepatocellular carcinoma tissues. Our findings indicate that NPC1 plays a key role in regulating neutrophil recruitment within the tumor, which is a critical factor in the progression of hepatocellular carcinoma and is closely linked to poor patient outcomes.

Rotational Correlation Functions of Single Molecules

, 2004
Single molecule rotational correlation functions are analyzed for several reorientation geometries. Even for the simplest model of isotropic rotational diffusion our findings predict non-exponential correlation functions to be observed by polarization ...

Fluorescent probes of the orientation of myosin regulatory light chains in relaxed, rigor, and contracting muscle. [PDF]

, 1996
The orientation of the light-chain region of myosin heads in relaxed, rigor, and isometrically contracting fibers from rabbit psoas muscle was studied by fluorescence polarization. Cysteine 108 of chicken gizzard myosin regulatory light chain (cgRLC) was

Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

FEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

Two-Photon Excited Fluorescence Dynamics in Enzyme-Bound NADH: the Heterogeneity of Fluorescence Decay Times and Anisotropic Relaxation [PDF]

arXiv, 2021
The dynamics of polarized fluorescence in reduced nicotinamide adenine dinucleotide (NADH) at 436~nm under two-photon excitation at 720~nm by femtosecond laser pulses in alcohol dehydrogenase (ADH)-containing buffer solution has been studied experimentally and theoretically.
