COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Concise and Efficient Multi-Identity Fully Homomorphic Encryption Scheme

IEEE Access
Combining multi-key fully homomorphic encryption (MKFHE) and identity-based encryption (IBE) to construct multi-identity based fully homomorphic encryption (MIBFHE) scheme can not only realize homomorphic operations and flexible access control on ...

Efficient Construction for Full Black-Box Accountable Authority Identity-Based Encryption

IEEE Access, 2019
Accountable authority identity-based encryption (A-IBE), as an attractive way to guarantee the user privacy security, enables a malicious private key generator (PKG) to be traced if it generates and re-distributes a user private key.

Traceable and Retrievable Identity-Based Encryption

, 2008
Very recently, the concept ofTraceable Identity-based Encryption (IBE) scheme (or Accountable Authority Identity based Encryption scheme) was introduced in Crypto 2007. This concept enables some mechanisms to reduce the trust of a private key generator (PKG) in an IBE system. The aim of this paper is threefold.

On the Power of Hierarchical Identity-Based Encryption [PDF]

, 2016
We prove that there is no fully black-box construction of collision-resistant hash functions CRH from hierarchical identity-based encryption HIBE with arbitrary polynomial number of identity levels. To the best of our knowledge this is the first limitation proved for HIBE.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Structural Identity-Based Encryption [PDF]

, 2007
In this paper, we introduce the concept of structural identity-based encryption (SIBE). Similar to hierarchical identity-based encryption (HIBE), entities in the system are organized into hierarchy.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Identity-Based Online/Offline Encryption Scheme from LWE

Information
With quantum computers, the quantum resistance of cryptographic systems has gradually attracted attention. To overcome the shortcoming of existing identity-based encryption (IBE) schemes in resisting quantum attacks, we introduce an IBE scheme based on ...

Identity-Based Matchmaking Encryption with Enhanced Privacy – A Generic Construction with Practical Instantiations

Identity-based matchmaking encryption (IB-ME), proposed by Ateniese et al. (Crypto 2019), is a type of matchmaking encryption (ME). In IB-ME, the sender can specify a target identity rcv during encryption, and the receiver can set a target identity snd ...
