In mammals, microRNAs (miRNAs) play key roles in controlling posttranscriptional regulation through binding to the mRNAs of target genes. Recently, it was discovered that viral miRNAs may be involved in human cancers and diseases. It is likely that viral miRNAs help viruses enter the latent phase of their life cycle and become undetected by the host's immune system, while increasing the host's risk for cancer development. Cervical cancer is typically related to the infection of human papillomavirus (HPV) through sexual transmission...

Anal squamous cell carcinoma (SCC) is the fourth most prevalent cancer in human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). Human papillomavirus (HPV) has been detected in over 90% of anal carcinoma biopsy specimens from MSM, and is considered a necessary, but alone, insufficient factor for carcinogenesis. Anal intraepithelial neoplasia (AIN) may be precursive for SCC, and screening cytology with referral of persons with abnormality for high-resolution anoscopy-guided biopsy, and AIN treatment, has been recommended for prevention...

We aimed to investigate the risk factors for cervical intraepithelial neoplasia (CIN) in Jiexiu, Shanxi Province, China. Twenty thousand eligible married women (age: 18-65 years) were administered with a questionnaire on potential risk factors for CIN and underwent liquid based Pap test. All women with abnormal cytological results underwent colposcopy with biopsy. Based on the biopsy pathology results, women were then assigned to either study group (with CIN) or control group (negative for histological results and volunteered to participate in the follow up study)...

In this study, a homogeneous polysaccharide (LEP1) with an average molecular weight of 53kDa was successfully purified from the fruiting bodies of Lentinus edodes and its anticancer efficacy on human cervical carcinoma HeLa cells in vitro and associated possible molecular mechanism were also evaluated. MTT assay showed that LEP1 exhibited a dose-dependent inhibitory effect on the proliferation of HeLa cells and caused apoptotic death. Our present findings provided the first evidence that LEP1 induced the apoptosis of HeLa cells via a mitochondria dependent pathway, as indicated by an increase in Bax/Bcl-2 ratio, a loss of mitochondrial membrane potential (Δym), the release of cytochrome c from the mitochondria to the cytosol, activation of caspase-9 and caspase-3, and cleavage of poly (ADP-ribose) polymerase (PARP) in HeLa cells...

The clinical management and treatment of cervical cancer, one of the most commonly diagnosed cancers and a leading cause of cancer-related female death, remains a huge challenge for researchers and health professionals. Cervical cancer can be categorized into two major subtypes: common squamous cell carcinoma (SCC) and adenocarcinoma (AC). Although it is a relatively rare histological subtype of cervical cancer, there has been a steady increase in the incidences of AC. Therefore, new strategies to treat cervical cancer are urgently needed...

A 69-year-old man presented with bulging of the right oropharyngeal wall, which revealed cytopathologically malignant cells. The man underwent MRI and F-FDG PET/CT, which demonstrated a cystic parapharyngeal lesion with an F-FDG-avid soft tissue component and right cervical lymph node. The patient was operated on and showed thyroid cancer in normal thyroid tissue, compatible with a papillary thyroid carcinoma in a lateral thyroglossal duct cyst and 2 ipsilateral lymph node metastases. Despite its rarity, papillary thyroid carcinoma in a thyroglossal duct cyst should be kept as one of the differential diagnoses in patients presenting with parapharyngeal cystic lesion...

BACKGROUND: Previous studies have demonstrated that ultrasonography is the recommended imaging modality for preoperative staging of papillary thyroid carcinomas (PTCs). However, only a few studies have kept watch on preoperative evaluation of capsular invasion (CI) or extracapsular extension (ECE) and cervical lymph node metastasis using preoperative ultrasonography. This study aimed to investigate the relationship between the CI or ECE and the cervical lymph node metastasis in PTCs using preoperative ultrasonography and postoperative pathology in Chinese patients...

Cervical carcinoma is the fourth most common cause of death in woman, caused by human papillomavirus (HPV) infections and arising from the cervix. Cytoskeleton-associated protein 2 (CKAP2), also known as tumor-associated microtubule-associated protein, has been linked to tumorigenic effects. In the present study, we screened CKAP2 as a new candidate gene which promotes development of cervical carcinoma, in two independent datasets (TCGA and GSE27678). Results showed that CKAP2 expression was significantly up-regulated in cervical cancerous tissues compared with normal counterparts...

The current recommended treatment for stage Ia2 cervical cancer is a radical or modified radical hysterectomy. Although in the United States the incidence of cervical cancer is low and declining, almost 50% of the over 4,000 new cases will present in early stages. An estimated 2,200 women each year will undergo radical hysterectomy and many will suffer from both early- and late-onset complications. The purpose of this review is to examine if there is still a role for radical hysterectomy in the proper treatment of stage Ia2 cervical cancer given most recent data...

BACKGROUND: Treatment for early-invasive adenocarcinoma of the cervix remains controversial. Although data have shown similar survival rates to those seen with squamous cell carcinoma, conservative options for patients with microinvasive adenocarcinoma have not been as widely accepted. Despite comparable survival outcomes, patients with early-invasive adenocarcinoma are still routinely subjected to more radical surgical techniques than their equivalently staged squamous cell counterparts...

Mammary serine protease inhibitor (maspin), encoded by the serpin family B member 5 gene, serves as a tumor suppressor through the inhibition of cancer cell invasion and metastasis. Paradoxically, maspin levels are upregulated in a number of types of malignant cells. Therefore, the regulation of maspin expression may depend on the genetic or epigenetic background and the specific microenvironment of carcinoma cells. In the present study, it was demonstrated that transforming growth factor β1 (TGF-β1) induced maspin expression at the transcript and protein levels in the human cervical carcinoma HeLa and human oral squamous carcinoma HSC4 cell lines...

Patients with cervical lymph node metastasis in squamous cell carcinoma of the head and neck (SCCHN) exhibit a poor prognosis and low 5-year survival rate. It has been proven that chemokine receptor 7 (CCR7) promotes cellular migration and invasion in metastatic SCCHN. In the present study, the metastatic SCCHN PCI-37B cell line was utilized to explore the role of Janus activated kinase-3 (Jak3) in the CCR7-mediated signaling pathway in metastatic SCCHN cells. It was observed that phospho-Jak3 was expressed in SCCHN tissues...

A reduced incidence and decreased clinical progression of uterine cervical intraepithelial neoplasia (CIN) has been observed in women infected with human immunodeficiency virus (HIV) treated with HIV-protease inhibitors (PIs). The HIV-PIs saquinavir (SQV) and ritonavir (RTV) have been demonstrated to efficiently inhibit invasion of human primary CIN cells by downregulating the expression of matrix metalloproteinase (MMP)-9. The present study further investigated the molecular mechanisms underlying the activity of SQV and RTV in CIN...
