Tripartite motif containing 28 (TRIM28) is a transcriptional regulator acting as an essential corepressor for Krüppel-associated box zinc finger domain-containing proteins in multiple tissue and cell types. An increasing number of studies have investigated the function of TRIM28; however, its prognostic value in breast cancer (BC) remains unclear. In the present study, the expression of TRIM28 was identified to be significantly higher in cancerous compared with healthy tissue samples. Furthermore, it was demonstrated that TRIM28 expression was significantly correlated with several clinicopathological characteristics of patients with BC, such as p53 mutation, tumor recurrence and Elston grade of the tumor...

Polycomb group (PcG) proteins form at least two key complexes, namely polycomb repressive complex 1 and polycomb repressive complex 2. These complexes are involved in the progression of various cancers. Systematic research has not been conducted on the aberrant expression of PcG members in gliomas. Using the Chinese Glioma Genome Atlas data set, PcG expression patterns between normal brain tissues and glioma samples were analyzed, and a PcG-based classifier was then developed using BRB Cox regression and risk-score model...

Krüppel-like factor 7 (KLF7) is a member of the KLF family of zinc finger transcription factors, and was the first KLF cloned using complementary DNA and polymerase chain reaction (PCR) techniques with human vascular endothelial cells as a template. In addition, KLF7 is known as the ubiquitous Krüppel-like factor, as it is widely expressed in numerous human tissues at low levels. In the present study, the function of KLF7 in migration and epithelial-mesenchymal transition (EMT), which are associated with tumor progression, was investigated in human oral squamous cell carcinoma (OSCC) cells...

BIX01294 (Bix) is known to be a euchromatic histone-lysine N-methyltransferase 2 inhibitor and treatment with Bix suppresses cancer cell survival and proliferation. In the present study, it was observed that sequential treatment with low-dose Bix notably increases glioblastoma cell migration and metastasis. It was demonstrated that U251 cells sequentially treated with low-dose Bix exhibited induced characteristic changes in critical epithelial-mesenchymal transition (EMT) markers, including E-cadherin, N-cadherin, β-catenin and zinc finger protein SNAI2...

BACKGROUND: Subacute rupture of the flexor tendons secondary to distal radius fractures is well documented. Recently, accounts of flexor tendon rupture following open reduction internal fixation have been associated with volar plate fixation. However, discovery of an occult traumatic flexor tendon laceration during fixation of an acute distal radius fracture is not well described. This case indicates the importance of careful preoperative and intraoperative examination of the flexor tendons in the setting of comminuted distal radius fractures...

BACKGROUND: Spontaneous flexor tendon rupture is rare and most common in the little finger. The pathogenesis of spontaneous tendon ruptures is unclear but may occur through attrition or mechanical abrasion over a bony prominence. Kienböck disease is avascular necrosis of the lunate, with an unknown etiology. METHODS: We present a case of spontaneous rupture of flexor digitorum profundus due to Kienböck disease, which we believe is the first recorded case of flexor tendon rupture attributable to osteonecrosis of the lunate...

BACKGROUND: The human hand is an important functional and sensory organ. Its complex anatomy reflects its important functional capabilities. Many Muslim countries observe the holy festivals with a traditional sacrifice of an animal in order to share the meat (basic commodity) with beloved ones. During such festivals hand injuries have been reported to increase. This study aimed to compare cases and controls of hand injuries treated at the national trauma center in the Sultanate of Oman during a 10-year time period...

BACKGROUND: Accurate identification of surface anatomy is critical to identify the location of the A1 pulley. The intercrease line (ICL) describes a transverse line between the radial edge of the proximal palmar crease and the ulnar edge of the distal palmar crease. We hypothesize that this easily identifiable surface landmark approximates the location of the A1 pulley. METHODS: The ICL was marked on 7 cadaver hands. We marked a point proximal to the proximal digital crease (PDC) equal to the distance between each digit's proximal interphalangeal crease (PIC) and PDC (the PIC/PDC point)...

A 45-year-old female patient presented to clinic with an almost completely embedded ring in the volar aspect of her right ring finger, with complete reepithelialisation over the superficial aspect of the ring. We present this unusual case of an embedded ring after an insect bite on the patient's ring finger. The patient had worn the ring for the previous 5 years without removing it and did not report any discomfort or traumatic injury. We discuss this case in the context of previously reported cases of an embedded ring, a rare presentation in itself, highlighting the key differences in both this patient's aetiology and the risk factors associated with the presentation...

The aim of this work is to remotely measure heart rate (HR) and respiratory rate (RR) using a video camera from long range (> 50 m). The proposed system is based on imperceptible signals produced from blood circulation, including skin colour variations and head motion. As these signals are not visible to the naked eye and to preserve the signal strength in the video, we used an improved video magnification technique to enhance these invisible signals and detect the physiological activity within the subject...

The exact mechanisms by which humans control the manual interception of moving targets are currently unknown. Here, the authors explored the behaviors associated with the spatial control for manual interception. The examined task required controlling a cursor to intercept moving targets on a touch screen. They explored the effects of target motion direction, curvature and occlusion on manual interception. They observed occlusion-dependent spatial errors and arrival times for curved and diagonal trajectories (larger errors and earlier arrival of the finger at its final position with longer occlusion)...

Macroautophagy, which will hereafter be referred to as autophagy, is an evolutionarily conserved process, during which cells recycle and remove damaged organelles and proteins in response to cellular stress. However, the mechanisms underlying the regulation of autophagy remain to be fully elucidated. The present study demonstrated that knockdown of zinc finger protein like 1 (ZFPL1) induces autophagy and increases autophagic cell death in NCI‑N87 and BGC‑823 human gastric carcinoma cell lines. To examine the role of ZFPL1 in gastric carcinoma cells, ZFPL1 expression was downregulated by lentiviral infection...

Genome wide association studies (GWAS) have mapped multiple independent cancer susceptibility loci to chr5p15.33. Here, we show that fine-mapping of pancreatic and testicular cancer GWAS within one of these loci (Region 2 in CLPTM1L) focuses the signal to nine highly correlated SNPs. Of these, rs36115365-C associated with increased pancreatic and testicular but decreased lung cancer and melanoma risk, and exhibited preferred protein-binding and enhanced regulatory activity. Transcriptional gene silencing of this regulatory element repressed TERT expression in an allele-specific manner...

Chromosomal rearrangements are essential events in the pathogenesis of both malignant and nonmalignant disorders, yet the factors affecting their formation are incompletely understood. Here we develop a zinc-finger nuclease translocation reporter and screen for factors that modulate rearrangements in human cells. We identify UBC9 and RAD50 as suppressors and 53BP1, DDB1 and poly(ADP)ribose polymerase 3 (PARP3) as promoters of chromosomal rearrangements across human cell types. We focus on PARP3 as it is dispensable for murine viability and has druggable catalytic activity...

BACKGROUND: Ring finger protein 43 (RNF43) is a member of the transmembrane E3 ubiquitin ligase family that was originally found in stem cells and plays important roles in tumor formation and progression. Our previous study indicated that RNF43 might be a tumor suppressor protein in gastric cancer. Given its antagonistic relationship with leucine-rich repeat-containing G-protein-coupled receptor 5 (Lgr5), one of the gastric cancer stem cell markers, investigation of the potential role of RNF43 in gastric stem cancer cells is necessary...

BACKGROUND: It is a challenge to reduce the muscular discoordination in the paretic upper limb after stroke in the traditional rehabilitation programs. METHOD: In this study, a neuromuscular electrical stimulation (NMES) and robot hybrid system was developed for multi-joint coordinated upper limb physical training. The system could assist the elbow, wrist and fingers to conduct arm reaching out, hand opening/grasping and arm withdrawing by tracking an indicative moving cursor on the screen of a computer, with the support from the joint motors and electrical stimulations on target muscles, under the voluntary intention control by electromyography (EMG)...
