High-intensity focused ultrasound treatment as an alternative regimen for myxofibrosarcoma.

Myxofibrosarcoma is a common soft-tissue sarcoma in elderly patients, characterized by an infiltrative growth pattern and a high risk for persistent local recurrence. A 35-years-old woman was diagnosed with myxofibrosarcoma on the right upper arm and the tumor is surgically resected. The tumor relapsed 7 months later.

Longikaurin A, a natural ent-kaurane, suppresses stemness in nasopharyngeal carcinoma cells.

Cancer stem cells (CSCs) are a small proportion of tumor cells that may be responsible for tumor metastasis and recurrence. Our recent research indicated that longikaurin A (LK-A) exhibited anti-tumor activity in nasopharyngeal carcinoma (NPC) both and . Here, we further investigated whether LK-A could suppress the stemness of NPC cells.

Polyphyllin I induces mitophagic and apoptotic cell death in human breast cancer cells by increasing mitochondrial PINK1 levels.

The molecular mechanisms underlying the anti-breast cancer effects of polyphyllin I, a natural compound extracted from Paris polyphylla rhizomes, are not fully understood. In the present study, we found that polyphyllin I induces mitochondrial translocation of DRP1 by dephosphorylating DRP1 at Ser637, leading to mitochondrial fission, cytochrome c release from mitochondria into the cytosol and, ultimately apoptosis. Polyphyllin I also increased the stabilization of full-length PINK1 at the mitochondrial surface, leading to the recruitment of PARK2, P62, ubiquitin, and LC3B-II to mitochondria and culminating in mitophagy.

Tonsil neuroendocrine carcinoma concurrent with hepatocellular carcinoma: A case report.

The majority of neuroendocrine tumors appear to be sporadic. Neuroendocrine carcinoma (NEC) typically arises in pancreatic, parathyroid and adrenal glands, but rarely arises in salivary glands. NEC of the tonsil is a rare type of tumor and the concurrent presentation of hepatocellular carcinoma (HCC) is considered to be more uncommon.

Prognostic relevance of Period1 (Per1) and Period2 (Per2) expression in human gastric cancer.

Period1 (Per1) and Period2 (Per2) are members of the circadian genes. Mounting evidence suggests that the deregulation of the circadian clock plays an important role in the development of mammalian cancer. However, the expression and clinical significance of Per1 and Per2 in gastric cancer is still unexplored.

Mitochondrial translocation of cofilin is required for allyl isothiocyanate-mediated cell death via ROCK1/PTEN/PI3K signaling pathway.

Background: Cofilin is a member of the actin depolymerizing factor (ADF)/cofilin family, which regulates actin dynamics. Increasing evidence suggests that mitochondrial translocation of cofilin appears necessary for the regulation of apoptosis.

Results: We report that allyl isothiocyanate (AITC) potently induces mitochondria injury and apoptosis.

[Expressions of OCT4 and CD133 and their correlation in colonic cancer].

Objective: To investigate the expressions of Oct4 and CD133 and their correlation in colonic cancer.

Methods: The expression of Oct4 and CD133 were detected by immunohistochemistry in 30 colon cancer specimens and the paired adjacent tissues.

Results: The positivity rates of Oct4 and CD133 expression were 83.

Multidisciplinary treatment with chemotherapy, targeted drug, and high-intensity focused ultrasound in advanced pancreatic carcinoma.

This study reports a case of an advanced pancreatic cancer patient with liver metastasis who was treated with a combination of chemotherapy, targeted drugs, and high-intensity focused ultrasound (HIFU). The abdominal pain was successfully relieved after the HIFU therapy. The patient had an 18-month survival with satisfactory quality of life.

[Efficacy of zoledronic acid combined with chemotherapy in treatment of skeletal metastases of non-small cell lung cancer and the bone metabolic markers].

Objective: To evaluate the clinical efficacy of zoledronic acid combined with chemotherapy in the management of skeletal metastasis of non-small cell lung cancer (NSCLC) and investigate the value in urine amino-terminal telopeptide of type I collagen (uNTX) and serum bone specific alkaline phosphatase (sBALP) in monitoring skeletal metastasis of NSCLC.

Methods: From February, 2007 to January, 2009, 32 NSCLC patients with bone metastases received treatment with zoledronic acid at the dose of 4 mg given every 3 weeks and platinum-based chemotherapy (each cycle lasting for 3 weeks). Before and during the treatments, uNTX and sBALP were measured in these patients using ELISA and precipitation with wheat germ lectin, respectively.

[Study on post-translational processing and active forms of the novel metastasis-associated protein SNC19].

Objective: To investigate the relationship between SNC19 protein and cancer metastasis.

Methods: Expression of SNC19 protein in cancer cell lines and tissues was examined by Western blot analysis using anti-SNC19 monoclonal antibody. In addition, Psectag2A-SNC19(ORF) eukaryotic expression vector was constructed and transfected into BCAP37 cells.
