Establishment of skin photoaging model and preliminary mechanism of senescence in keratinocytes cell line HaCaT

open access: yesDi-san junyi daxue xuebao, 2019
Objective To establish an efficient skin photoaging model in HaCaT cells and investigate the possible signaling pathways of photoaging of skin. Methods After HaCaT cells were exposed to UVB at 30 mJ/cm2, cell proliferation and cell cycle was detected by ...

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

open access: yesAdvanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Cytoplasmic p21 induced by p65 prevents doxorubicin-induced cell death in pancreatic carcinoma cell line

open access: yesJournal of Biomedical Science, 2012
Background Studies have shown the existence of p21 induction in a p53-dependent and -independent pathway. Our previous study indicates that DOX-induced p65 is able to bind the p21 promoter to activate its transactivation in the cells.

CP Asymmetry in Charged Higgs Decays in MSSM [PDF]

open access: yes, 2007
We discuss and compare the charge-parity (CP) asymmetry in the charged Higgs boson decays H -> \bar{u}_i d_j for the second and third generation quarks in the minimal supersymmetric standard model.

Cytoplasmic translocation of p21 mediates NUPR1‐induced chemoresistance [PDF]

open access: yesFEBS Letters, 2012
The expression of Nuclear Protein 1 (NUPR1) is associated with chemoresistance in multiple malignancies. We previously reported that NUPR1 functions as a transcriptional cofactor for the p300–p53 complex and transcriptionally regulates p21 expression.

Self‐Cooling Molecular Spin Qudits

open access: yesAdvanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Long-term prognostic value of the combination of EORTC risk group calculator and molecular markers in non-muscle-invasive bladder cancer patients treated with intravesical Bacille Calmette-Guérin

open access: yesUrology Annals, 2011
Background and Objectives: To evaluate the long-term prognostic value of the combination of the EORTC risk calculator and proapoptotic, antiapoptotic, proliferation, and invasiveness molecular markers in predicting the outcome of intermediate- and high ...

Downregulation of GLYR1 contributes to microsatellite instability colorectal cancer by targeting p21 via the p38MAPK and PI3K/AKT pathways

open access: yesJournal of Experimental & Clinical Cancer Research, 2020
Background GLYR1 has a high mutation frequency in microsatellite instability colorectal cancer (MSI CRC) and is presumed to be a novel tumor suppressor. However, the role of GLYR1 in tumors has never been studied.

PBRM1 acts as a p53 lysine-acetylation reader to suppress renal tumor growth. [PDF]

open access: yes, 2019
p53 acetylation is indispensable for its transcriptional activity and tumor suppressive function. However, the identity of reader protein(s) for p53 acetylation remains elusive. PBRM1, the second most highly mutated tumor suppressor gene in kidney cancer,

Bicomplex Hamiltonian systems in Quantum Mechanics

open access: yes, 2015
We investigate bicomplex Hamiltonian systems in the framework of an analogous version of the Schrodinger equation. Since in such a setting three different types of conjugates of bicomplex numbers appear, each is found to define in a natural way, a ...
