Transforming growth factor-beta (TGF-beta) was originally identified, characterized, and named on the basis of its ability to induce anchorage-independent growth (phenotypic transformation). This effect has received little attention in recent years, probably because the induction of anchorage-independent growth by TGF-beta has been observed only in a few cell lines, of which NRK fibroblasts are...
Protein kinase C (PKC) isozymes have remained elusive cancer targets despite the unambiguous tumor promoting function of their potent ligands, phorbol esters, and the prevalence of their mutations. We analyzed 8% of PKC mutations identified in human cancers and found that, surprisingly, most were loss of function and none were activating. Loss-of-function mutations occurred in all PKC subgroups...
INTRODUCTION This study was conducted to determine the efficiency of mini-implants as intraoral anchorage units for en-masse retraction of the 6 maxillary anterior teeth when the first premolars are extracted compared with conventional methods of anchorage reinforcement. METHODS Thirty patients requiring high anchorage after extraction of the maxillary first premolars were selected for this s...
Mammalian cells generally require both mitogens and anchorage signals in order to proliferate. An important characteristic of many tumour cells is that they have lost this anchorage-dependent cell-cycle checkpoint, allowing them to proliferate without signals provided by their normal microenvironment. In the absence of anchorage signals from the extracellular matrix, many cell types arrest cell...
Background and purpose: Skeletal anchorage is a new aid for the correction of moderate anterior open bite. This study aimed at treating moderate anterior open bite using posterior intrusion via mini implants. In addition, a review of studies carried out on open bite correction using absolute anchorage was performed. Materials and methods: The following keywords were used: open bite, camouflag...
BACKGROUND The purpose of this systematic review is to identify and review the orthodontic literature with regards to assessing possible differences in canine retraction rate and the amount of antero-posterior anchorage (AP) loss during maxillary canine retraction, using conventional brackets (CBs) and self-ligating brackets (SLBs). METHODS An electronic search without time or language restri...
BACKGROUND The aim of this study was to present a temporary anchorage device with intraosseous screw for unilateral molar distalization to make a space for the impacted premolar and to found well balanced occlusion in a case. CASE PRESENTATION A 13-year-old male who have an impacted premolar is presented with skeletal Class I and dental Class 2 relationship. The screw was placed and immediate...
HIC-5 is a multidomain LIM protein homologous to paxillin that serves as a molecular scaffold at focal adhesions and in the nucleus. It forms mobile molecular units with LIM-only proteins, PINCH, and CRP2 and translocates in and out of the nucleus via a nuclear export signal (NES). Of note, NES of HIC-5 is distinctive in its sensitivity to the cellular redox state. Recently, the mobile units of...
