AIMS

To determine the value of a monoclonal antibody panel against a C-terminal conserved sequence polypeptide of human papillomavirus (HPV) L1 (a major capsid protein) for the detection of HPV in cervical exfoliated cells, as well as the potential of this antibody panel to be developed into an assay kit for the clinical screening of cervical cancer.

METHODS

Cervical exfoliated cells were collected at a gynecology clinic. One part of each sample was sent to the Department of Pathology for HPV genotyping, and the other part was sent to the Department of Pathology for cytologic testing and then to the laboratory for immunological histological chemistry (IHC) assay in which an HPV L1 C-terminal conserved sequence polypeptide-induced mouse monoclonal antibody panel was used to detect HPV L1.

RESULTS

Cervical cell samples were collected from 514 patients at the gynecology clinic; of these, 339 samples were sent for HPV genotyping, and 220 were HPV positive (64.90%, 220/339). Moreover, the duplicate samples from these 339 patients were sent for IHC assay, and 229 samples were positive (67.55%, 229/339). The IHC result was concordant with that obtained by HPV genotyping

CONCLUSION

This study showed that use of the HPV L1 C-terminal conserved sequence polypeptide-induced mouse monoclonal antibody panel was of great value for the detection of HPV in cervical cells; the resulting detection rate was comparable to that obtained using the commercial HPV genotyping kit that is currently in use in clinical practice.

Deubiquitinating enzyme USP9X regulates cellular clock function by modulating the ubiquitination and degradation of a core circadian protein BMAL1

Author：Yang Zhang, Chunyan Duan, Jing Yang, Suping Chen,  Qing Liu, Liang Zhou, Zhengyun Huang, Ying Xu, Guoqiang Xu     《Biochemical Journal》 ABSTRACTS Living organisms on the earth maintain a roughly 24 h circadian rhythm, which is regulated by circadian clock genes as well as their protein products. Post-translational modifications of core clock proteins could affect the circadian behavior. Although ubiquitination of core clock proteins was studied extensively, the reverse process, deubiquitination, has only begun to unfold and the role of this regulation on circadian function is not completely understood. Here, we use affinity purification and mass spectrometry analysis to identify probable ubiquitin carboxyl-terminal hydrolase FAF-X (USP9X) as an interacting protein of the core clock protein aryl hydrocarbon receptor nuclear translocator-like protein 1 (ARNTL or BMAL1). Through biochemical experiments, we discover that USP9X reduces BMAL1 ubiquitina...

Targeting the leptin receptor: To evaluate therapeutic efficacy and anti-tumor effects of Doxil, in vitro and in vivo in mice bearing C26 colon carcinoma tumor

Author：Shahrzad Amiri Darban, Sara Nikoofal-Sahlabadi,  Nafise Amiri, Nafiseh Kiamanesh, Amin Mehrabian, Bamdad Zendehbad, Zahra Gholizadeh, Mahmoud Reza Jaafari     《Colloids and Surfaces B: Biointerfaces》 ABSTRACTS Leptin is an appetite regulatory hormone that is secreted into the blood circulation by the adipose tissue and it functions via its over expressed receptors (Ob-R) in a wide variety of cancers. In the present study, the function of a leptin-derived peptide (LP16, 91–110 of Leptin) was investigated as a targeting ligand to decorate PEGylated liposomal doxorubicin (PLD, Doxil ? ) surface and the anti-tumor activity and therapeutic efficacy of Doxil in C26 (Colon Carcinoma) tumor model were also evaluated. As a result of this, Doxil with different LP16 peptide density (25, 50, 100 and 200 peptide on the surface of each liposome) was successfully prepared and characterized. In vitro results showed significant enhanced cytotoxicity and cellular b...
