The spindle and kinetochore-associated complex subunit 1(SKA1) is a newly discovered gene, which has been associated with mitosis and tumorigenesis. However, its role insalivary adenoid cystic carcinoma (SACC) is still unknown, and the invasive and metastatic mechanism in SACC is still unclear. To explore the molecular mechanism of SKA1 in the process of malignant proliferation and metastasis in adenoid cystic cancer (ACC) cells, we employed lentivirus-mediated short hairpin RNA to knockdown SKA1 in SACC-83 cells...

Salivary adenoid cystic carcinoma (AdCC) is a common head and neck cancer with the propensity for local spread and distant metastasis. In our previous study, elevated expression of Anterior gradient 2 (AGR2) was detected in head and neck squamous cell carcinoma (HNSCC), associated with epithelial-mesenchymal transition (EMT) and cancer stemness. However, to date, the expression and function of AGR2 in AdCC has yet to be elucidated. In the present study, human AdCC tissue microarrays including 18 cases of normal salivary gland (NSG), 12 cases of pleomorphic adenoma (PMA) and 72 cases of AdCC were employed for immunohistochemical staining analysis...

Anogenital mammary-like glands (AGMLGs) are nowadays considered a normal component of the anogenital area. Lesions involving AGMLGs are histopathologically very similar to their mammary counterparts, but the information on molecular biological mechanisms in these vulvar/perianal tumors is scarce. Mutations in the PI3K-AKT cascade have been found in hidradenoma papilliferum. The authors studied selected BRCA1, BRCA2, and PIK3CA mutations in series of benign and malignant neoplasms thought to be associated with AGMLGs, including 9 cases of primary extramammary Paget disease, 3 different cases of mammary-type carcinoma (adenoid cystic like, tubulolobular, and invasive ductal like), and 5 cases of hidradenoma papilliferum...

Previous studies have shown that miR-222 targets the p53 upregulated modulator of apoptosis (PUMA) to regulate cell biological behavior in some human malignancies. We hypothesized that there was a negative regulation, which might induce apoptosis, between miR-222 and PUMA in adenoid cystic carcinoma (ACC). In this study, the expression levels of miR-222 and the PUMA gene after transfection with antisense miR-222 (As-miR-222) were evaluated by RT-PCR and Western blot assays. Cell proliferation and migratory abilities were detected by CCK-8 and Transwell assays...

Salivary gland carcinomas (SGCs) represent one of the most complex tumors from a pathological point of view. According to the World Health Organization (WHO) classification (2005), twenty-four malignant histotypes are recognized, almost all characterized by specific morphological and genetic features as well as by particular clinical behavior. Loco-regional relapse and distant metastases are quite common. Distant metastases are diagnosed in 25-55% of the patients and only 20% of them are alive after 5years...

Primary cutaneous adenoid cystic carcinoma (PCACC) is a very rare malignancy. The differential diagnosis of PCACCs in pathology practice can be difficult and a group of primary and metastatic lesions, including adenoid basal cell carcinoma of the skin, should be considered in the differential diagnosis. Besides histomorphological clues, immunohistochemistry studies are very helpful in the differential diagnosis of PCACC. We report herein a case of PCACC with extensive immunohistochemical studies and review the literature from an immunohistochemistry perspective...

Sometimes pain originating from a non-odontogenic pathologic condition is mistaken as endodontic illness, leading to misdiagnosis. The patient can misinterpret the pain as originating from a site different from the actual site, which is known as referred pain. However, the clinician managing pain in the orofacial region needs to be well-informed about the typical signs and symptoms of non-odontogenic diseases and to be able to make the correct referral when necessary for proper diagnosis and treatment. A 43-year-old man presented to the department of conservative dentistry complaining of dental pain...

Genomic profiling is widely predicted to become a standard of care in clinical oncology, but more effective data sharing to accelerate progress in precision medicine will be required. Here we describe cancer-associated genomic profiles from 18,004 unique adult cancers. The dataset was composed of 162 tumor subtypes including multiple rare and uncommon tumors. Comparison of alteration frequencies to The Cancer Genome Atlas (TCGA) identified some differences and suggested an enrichment of treatment-refractory samples in breast and lung cancer cohorts...

Provirus integration site for Moloney murine leukemia virus 1 (Pim-1) has proved to be an oncogene and it is known that to depress Pim-1 activity may be a novel oncological treatment strategy. SGI-1776, a small molecule, is the first clinically tested inhibitor of the Pim kinase family. Here, we aimed to explore the effect of SGI-1776 on salivary adenoid cystic carcinoma (SACC). Expression of Pim-1 was confirmed in SACC and control tissues by qRT-PCR. After SGI-1776 treatment, the Pim-1 expressions and Pim-1 kinase activity in both SACC-83 and SACC-LM cell lines were measured...
