#1
Ling Lin, Xuexia Lin, Luyao Lin, Qiang Feng, Takehiko Kitamori, Jin-Ming Lin, Jiashu Sun
Interaction between tumor and endothelial cells could affect tumor growth and progression, and induce drug resistance during cancer therapy. Investigation on tumor-endothelial cell interaction involves cell co-culture, protein detection, and analysis of drug metabolites, which are complicated and time-consuming. In this work, we present an integrated microfluidic device with three individual components (the cell co-culture component, the protein detection component, and the pre-treatment component for drug metabolites) to probe the interaction between tumor and endothelial cells...

REVIEW
Chelsey C Spriggs, Laimonis A Laimins
High-risk human papillomaviruses (HPVs) are the causative agents of cervical and other genital cancers. In addition, HPV infections are associated with the development of many oropharyngeal cancers. HPVs activate and repress a number of host cellular pathways to promote their viral life cycles, including those of the DNA damage response. High-risk HPVs activate the ataxia telangiectasia-mutated (ATM) and ATM and Rad3-related (ATR) DNA damage repair pathways, which are essential for viral replication (particularly differentiation-dependent genome amplification)...

The present study explored the effect that deoxycytidine kinase (DCK) knockdown had on proliferation, apoptosis and tumorigenicity in vivo of cervical cancer HeLa cells. Human cervical cancer HeLa cells that had received no prior treatment were selected from the HeLa group. The HeLa-negative control (NC) group consisted of cells that had undergone an empty vector treatment, and finally the HeLa-short hairpin RNA (shRNA) group included cells that were treated by means of shRNA-DCK expression. DCK expressions were evaluated by quantitative real-time polymerase chain reaction in addition to western blotting assays...

Since the initial recognition of acquired immunodeficiency syndrome (AIDS) in 1981, an increased burden of cervical cancer was identified among human immunodeficiency virus (HIV)-positive women. Introduction of antiretroviral therapy (ART) decreased risks of opportunistic infections and improved overall survival. HIV-infected women are living longer. Introduction of the human papillomavirus (HPV) vaccine, cervical cancer screening and early diagnosis provide opportunities to reduce cervical cancer associated mortality...

Parathyroid carcinoma is a very rare malignant tumor of the parathyroid gland. Clinically, this cancer is characterized by the presence of severe primary hyperparathyroidism. Diagnosis is based on histological examination but is not always easy. Surgery is the treatment of choice. We report the case of a 59-year old woman with a personal history of arterial hypertension and of recurrent renal lithiasis, presenting with diffuse bone pain associated with asthenia. Neck examination showed hard basi-cervical swelling with nonpalpable lower edge...

Small cell neuroendocrine carcinomas of the gynecologic tract are unusual, accounting for only 2% of the cervical cancers. Given the rarity of these tumors and the absence of randomized trials, their diagnosis and treatment programmes are difficult and are essentially based on those of neuroendocrine tumors of the lung. As in the case of the neuroendocrine tumors of the lung and despite multimodal treatment they are associated with a poor prognosis. We here report a new case of small cell neuroendocrine carcinoma of the cervix and, throught a literature review, we highlight the various aspects of this rare entity...

SZRD1 is a novel gene screened out by high-throughput platform, and so far there exists no systematic function reports. The purpose of our study is to discover the function and mechanism of this novel human gene. Bioinformatics analysis indicates that SZRD1 is a highly conserved intracellular protein. After overexpression of SZRD1, we found that SZRD1 could arrest the cell cycle in G2 phase and play a role in inhibiting cell proliferation and inducing apoptosis. In contrast, after knockdown of endogenous SZRD1, we concluded that it could promote cell proliferation...

Health literacy, the degree to which individuals have the capacity to obtain, process, and understand health information and services needed to make health decisions, is an essential element for early adults (aged 18-44 years) to make informed decisions about cancer. Low health literacy is one of the social determinants of health associated with cancer-related disparities. Over the past several years, a nonprofit organization, a university, and a cancer center in a major urban environment have developed and implemented health literacy programs within healthcare systems and in the community...

In Thailand, five cancer types-breast, cervical, colorectal, liver and lung cancer-contribute to over half of the cancer burden. The magnitude of these cancers must be quantified over time to assess previous health policies and highlight future trajectories for targeted prevention efforts. We provide a comprehensive assessment of these five cancers nationally and subnationally, with trend analysis, projections, and number of cases expected for the year 2025 using cancer registry data. We found that breast (average annual percent change (AAPC): 3...
