First Observation of the Decays chi_{cJ} -> pi^0 pi^0 pi^0 pi^0

open access: yes, 2010
We present a study of the P-wave spin -triplet charmonium chi_{cJ} decays (J=0,1,2) into pi^0 pi^0 pi^0 pi^0. The analysis is based on 106 million \psiprime decays recorded with the BESIII detector at the BEPCII electron positron collider. The decay into

Mechanobiology of the Nucleolus

open access: yesBiology of the Cell, Volume 118, Issue 2, February 2026.
Mechanical forces reshape nuclear structure and reorganize the nucleolus, altering its role in ribosome biogenesis. This review examines how mechanical cues impact nucleolar assembly and function. We propose that the nucleolus acts as a mechano‐responsive condensate integrating mechanical stress with cellular homeostasis.

Role of KASH domain lengths in the regulation of LINC complexes. [PDF]

open access: yes, 2019
The linker of the nucleoskeleton and cytoskeleton (LINC) complex is formed by the conserved interactions between Sad-1 and UNC-84 (SUN) and Klarsicht, ANC-1, SYNE homology (KASH) domain proteins, providing a physical coupling between the nucleoskeleton ...

Measurement of the branching fractions of psi(2S) -> 3(pi+pi-) and J/psi -> 2(pi+pi-)

open access: yes, 2005
Using data samples collected at sqrt(s) = 3.686GeV and 3.650GeV by the BESII detector at the BEPC, the branching fraction of psi(2S) -> 3(pi+pi-) is measured to be [4.83 +- 0.38(stat) +- 0.69(syst)] x 10^-4, and the relative branching fraction of J/psi ->

A conserved KASH domain protein associates with telomeres, SUN1, and dynactin during mammalian meiosis [PDF]

open access: yesJournal of Cell Biology, 2012
In yeasts and worms, KASH (Klarsicht/ANC-1/Syne/homology) domain and SUN (Sad-1/UNC-84) domain nuclear envelope (NE) proteins play a crucial role in meiotic chromosome movement and homologue pairing. However, although the vertebrate SUN domain protein SUN1 is involved in these processes, its partner has remained identified.

Search for psi(3770)\ra\rho\pi at the BESII detector at the Beijing Electron-Positron Collider

open access: yes, 2005
Non-$D\bar{D}$ decay $\psppto \rhopi$ is searched for using a data sample of $(17.3\pm 0.5) pb^{-1}$ taken at the center-of-mass energy of 3.773 GeV by the BESII detector at the BEPC.

Search for the isospin violating decay $Y(4260)\rightarrow J/\psi \eta \pi^{0}$ [PDF]

open access: yes, 2015
Using data samples collected at center of mass energies of $\sqrt{s}$ = 4.009, 4.226, 4.257, 4.358, 4.416 and 4.599 GeV with the BESIII detector operating at the BEPCII storage ring, we search for the isospin violating decay $Y(4260)\rightarrow J/\psi ...

SUN1 splice variants, SUN1_888, SUN1_785, and predominant SUN1_916, variably function in directional cell migration [PDF]

open access: yesNucleus, 2016
The LINC complex is a multifunctional protein complex that is involved in various processes at the nuclear envelope, such as nuclear migration, mechanotransduction and chromatin tethering in the meiotic phase. However, it remains unknown how these functions are regulated in different cell contexts.

Astrocytic Chromatin Remodeler ATRX Gates Hippocampal Memory Consolidation Through Metabolic and Synaptic Regulation

open access: yesGlia, Volume 74, Issue 1, January 2026.
Astrocytic ATRX loss causes non‐cell‐autonomous neuronal hyperexcitability. Inducing ATRX deficiency in astrocytes causes selective long‐term memory deficits. Dynamic transcriptomic changes reveal metabolic and synaptic pathway dysregulation. ABSTRACT Astrocytes are increasingly recognized as active regulators of synaptic transmission and memory, yet ...
