The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Efficient identification protocol provably secure in standard model

open access: yesTongxin xuebao, 2009
Based on the hardness assumption of the collusion attack algorithm with k traitors (K-CAA) in a gap Diffie-Hellman (GDH) group, a new and efficient identification protocol is proposed.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Efficient chosen-ciphertext secure proxy re-encryption scheme

open access: yesTongxin xuebao, 2013
In order to construct an efficient and chosen-chiphertext secure unidirectional re-encryption scheme in the standard model,a novel and efficient unidirectional proxy re-encryption scheme was proposed, and its chosen-ciphertext security in the adaptive ...

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Adaptively secure key-policy ABE scheme with fast decryption

open access: yesTongxin xuebao, 2014
In the existing adaptively secure ABE (attribute-based encryption) schemes,the decryption cost goes linearly with the number of attributes that are used in decryption.An adaptively secure key-policy ABE (FKP-ABE) scheme with fast decryption is proposed ...
