En Block Versus Separate Management of Cervical Nodes in Tongue and Floor of the Mouth Cancers- Is There a Difference? An Analysis of 85 Cases in a Tertiary Care Institute.

To evaluate difference in local recurrence, regional (neck) recurrence as well as distant metastases between cases operated with en-block excision of primary cancer and neck nodes versus their separate removal, in squamous cell carcinomas of anterior 2/3 of tongue and floor of the mouth. A total 85 patients of cT1-T4a N0-N2b of carcinoma anterior 2/3 of tongue and floor of mouth were evaluated. Amongst these patients 39 cases of in-continuity en-block neck dissection and 46 cases of discontinuous neck dissection were evaluated for post-operative complications as well as oncological outcome for a follow up period of 3 years.

Autoreconstruction of the tongue in case of extensive verrucous carcinoma.

Tongue reconstruction can be simple to complex depending on the size of the defect. Reconstruction of medium-to-large size defect is technically demanding to achieve better esthetic and functional outcome. There are various options in the reconstruction of tongue defect when it comes to the type of flap.

Mango-shaped Bi-paddled pectoralis major myocutaneous flap reconstruction for large full-thickness defects post resection of squamous cell carcinoma of oral cavity: An analysis of 232 cases.

Objectives: The objective of the study was to examine the feasibility of bi-paddled pectoralis major myocutaneous (PMMC) flap reconstruction in patient undergoing full thickness composite resection.

Materials And Methods: Inclusion criteria: The subjects chosen were patients with clinically T4A squamous cell carcinoma of buccal mucosa, lower alveolus, and maxilla in with skin involvement. Patients required a full-thickness composite resection of intraoral lesion, bone (mandibular segment and/or maxilla), and overlying involved skin and had modified radical neck dissection.

Preferential CEBP binding to T:G mismatches and increased C-to-T human somatic mutations.

DNA cytosine methylation in mammals modulates gene expression and chromatin accessibility. It also impacts mutation rates, via spontaneous oxidative deamination of 5-methylcytosine (5mC) to thymine. In most cases the resulting T:G mismatches are repaired, following T excision by one of the thymine DNA glycosylases, TDG or MBD4.

KRAB domain of ZFP568 disrupts TRIM28-mediated abnormal interactions in cancer cells.

Interactions of KRAB (Krüppel-associated box)-associated protein KAP1 [also known as TRIM28 (tripartite motif containing protein 28)] with DNA-binding KRAB zinc finger (KRAB-ZF) proteins silence many transposable elements during embryogenesis. However, in some cancers, TRIM28 is upregulated and interacts with different partners, many of which are transcription regulators such as EZH2 in MCF7 cells, to form abnormal repressive or activating complexes that lead to misregulation of genes. We ask whether a KRAB domain-the TRIM28 interaction domain present in native binding partners of TRIM28 that mediate repression of transposable elements-could be used as a tool molecule to disrupt aberrant TRIM28 complexes.

PARP-1/2 Inhibitor Olaparib Prevents or Partially Reverts EMT Induced by TGF-β in NMuMG Cells.

Poly- adenosine diphosphate (ADP)-ribose (PAR) is a polymer synthesized as a posttranslational modification by some poly (ADP-ribose) polymerases (PARPs), namely PARP-1, PARP-2, tankyrase-1, and tankyrase-2 (TNKS-1/2). PARP-1 is nuclear and has also been detected in extracellular vesicles. PARP-2 and TNKS-1/2 are distributed in nuclei and cytoplasm.

The calcium channel proteins ORAI3 and STIM1 mediate TGF-β induced expression.

Calcium influx into cells via plasma membrane protein channels is tightly regulated to maintain cellular homeostasis. Calcium channel proteins in the plasma membrane and endoplasmic reticulum have been linked to cancer, specifically during the epithelial-mesenchymal transition (EMT), a cell state transition process implicated in both cancer cell migration and drug resistance. The transcription factor SNAI1 (SNAIL) is upregulated during EMT and is responsible for gene expression changes associated with EMT, but the calcium channels required for expression remain unknown.

Leptin receptor signaling via Janus kinase 2/Signal transducer and activator of transcription 3 impacts on ovarian cancer cell phenotypes.

Ovarian cancer is a leading cause of cancer mortality in women world-wide. Considerable progress has been made to characterize the different subtypes of ovarian cancer, but specific therapies remain limited and prognosis poor. Cytokine signaling via the interleukin-6 receptor (IL-6R) family and related receptors has been implicated in a number of cancers, including those with an ovarian origin.

Role of the interleukin 6 receptor family in epithelial ovarian cancer and its clinical implications.

Ovarian cancer is the most lethal gynecological malignancy, with few effective treatment options in most cases. Therefore, understanding the biology of ovarian cancer remains an important area of research in order to improve clinical outcomes. Cytokine receptor signaling through the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway is an essential component of normal development and homeostasis.

Alternative TEL-JAK2 fusions associated with T-cell acute lymphoblastic leukemia and atypical chronic myelogenous leukemia dissected in zebrafish.

Background: Chromosomal translocations resulting in alternative fusions of the human TEL (ETV6) and JAK2 genes have been observed in cases of acute lymphoblastic leukemia and chronic myelogenous leukemia, but a full understanding of their role in disease etiology has remained elusive. In this study potential differences between these alternative TEL-JAK2 fusions, including their lineage specificity, were investigated.

Design And Methods: TEL-JAK2 fusion types derived from both T-cell acute lymphoblastic leukemia and atypical chronic myelogenous leukemia were generated using the corresponding zebrafish tel and jak2a genes and placed under the control of either the white blood cell-specific spi1 promoter or the ubiquitously-expressed cytomegalovirus promoter.

Cisplatin treatment of primary and metastatic epithelial ovarian carcinomas generates residual cells with mesenchymal stem cell-like profile.

Epithelial mesenchymal transition (EMT) and cancer stem cells (CSC) have been associated with resistance to chemotherapy. Eighty percent of ovarian cancer patients initially respond to platinum-based combination therapy but most return with recurrence and ultimate demise. To better understand such chemoresistance we have assessed the potential role of EMT in tumor cells collected from advanced-stage ovarian cancer patients and the ovarian cancer cell line OVCA 433 in response to cisplatin in vitro.
