Purpose: Tumor drug resistance limits the response to chemotherapy. Interestingly, sequential combination therapy enhances the anticancer efficacy of drugs like cisplatin (CDDP) via synergistic effects. We assayed the synergistic effects of combined photodynamic therapy programmed death receptor-ligand 1 (PDT) and chemotherapy in malignant Hep-2 cells.

It has been well documented that Snail plays a decisive role in various tumors. However, the direct effect of Snail on laryngeal squamous cell carcinoma (LSCC) has not been elaborated. In this study, we firstly detected the expression of Snail in 14 samples of patients with LSCC and found that its content was high in cancer tissues compared with adjacent tissues.

Background: Nasopharyngeal carcinoma (NPC) is a common head and neck cancer with an incidence of 10-30 cases per 100,000 in southern China. Although primary treatment includes radiation therapy, prognosis is still unsatisfactory.

Objective: In this study, we examined the role of HNF1A-AS in NPC progression in vitro and in vivo.

Mesoporous silica nanoparticles (MSNs) represent a new form of drug nanocarrier with thermo/pH-coupling sensitivity and site-specificity. CD133(+) Hep-2 laryngeal cancer cells are responsible for multidrug resistance due to elevated expression of ABCG2. Since positively charged nanoparticles could easily uptake nucleic acids, we examined the possibility of using this new drug delivery system to simultaneously deliver different chemotherapeutic drugs and siRNA targeting ABCG2.

Angioleiomyoma is a rare benign vascular smooth muscle tumor that arise from the tunica media of veins and arteries. Here a case of laryngeal angioleiomyoma in a 57-year-old Chinese man is reported. The patient presented with dysphagia for one and half-month and dyspnea during the previous one week, was hospitalized for treatment with a tracheotomy and laryngofissure with the unblock mass excision.

Follicular dentritic cell sarcoma (FDCS) is an extremely rare malignant neoplasm arising from the accessory cells of the lymph nodes, the follicular dendritic cells. They commonly occur in the lymph nodes, but have also been reported at extranodal sites. Because of its rarity, FDCS is not easily to make a diagnosis by clinicians or pathologists.

Endoscopy is essential for the diagnosis and treatment of cancers derived from the larynx. However, a laryngoscope with conventional white light (CWL) has technical limitations in detecting small or superficial lesions on the mucosa. Narrow band imaging especially combined with magnifying endoscopy (ME) is useful for the detection of superficial squamous cell carcinoma (SCC) within the oropharynx, hypopharynx, and oral cavity.

The objective of this study is to investigate the chemoresistance of CD133(+) cancer stem cells in Hep-2 cells of laryngeal cancer and detect the expression mRNA and protein levels of BMI-1 in CD133(+) cells and CD133(-) cells. The response of Hep-2 cells to different chemotherapeutic agents was investigated, and the expression of CD133 was studied. Fluorescence-activated cell sorting analysis was used to identify CD133, and the CD133(+) subset of cells was separated and analyzed chemotherapy resistance.

Chemoresistance is one of the major barriers to chemotherapeutic treatment and it has been established that CD133 cancer stem cells are responsible for drug resistance in laryngeal carcinoma. In the present study, curcumin and cisplatin were used as a combined treatment to induce the sensitivity of CD133 cancer stem cells to chemotherapeutic agents and to enhance therapeutic effectiveness. The results revealed that in untreated and cisplatin-treated HEp-2 cell groups, the percentage of CD133 cells was 4.

Article Synopsis
  • An effective cancer therapy should specifically target tumors while minimizing side effects.
  • Researchers engineered a weakened strain of Salmonella typhimurium to deliver a gene called Apoptin into human cancer cells, showing increased cell death through a specific cellular pathway.
  • Tests in mice demonstrated that this recombinant bacteria slowed tumor growth and improved survival rates, suggesting its promise as a cancer treatment.

Objective: To investigate the inhibitory effect of plasmid-based survivin-specific short hairpin RNA and GRIM-19 on the growth of Hep-2 laryngeal cancer cells.

Methods: The plasmid expressing survivin-specific short hairpin RNA (shRNA) and GRIM-19 (p-siRNA survivin/GRIM-19) was prepared and transfected into Hep-2 cells with Lipofectamine 2000. The mRNA and protein expression of surviving and GRIM-19 were measured with RT-PCR and western blot assay, respectively.

In this study, we try to detect and isolate the cancer stem cell-like side population cells (SP) from the laryngeal carcinoma cell line and primary laryngeal carcinoma and explore the clinical implications of SP cells in laryngeal carcinoma. The SP cells and non-side population cells (NSP) cells were sorted by Hoechst 33342 through FACS. The proliferation capacity, invasion ability, migration ability, and tumorigenic activity of the SP cells were evaluated.

Background: Mounting evidence suggests that tumors are histologically heterogeneous and are maintained by a small population of tumor cells termed cancer stem cells. CD133 has been identified as a candidate marker of cancer stem cells in laryngeal carcinoma. This study aimed to analyze the chemoresistance of CD133(+) cancer stem cells.
