Lipid Droplets in Lung Cancers Are Crucial for the Cell Growth and Starvation Survival.

For rapid and unlimited cell growth and proliferation, cancer cells require large quantities of nutrients. Many metabolic pathways and nutrient uptake systems are frequently reprogrammed and upregulated to meet the demand from cancer cells, including the demand for lipids. The lipids for most adult normal cells are mainly acquired from the circulatory system.

The potential and limitation of targeted chromosomal breakpoint sequencing for the fusion gene identification in lung cancer.

fusion genes are rare but important driver genes in lung cancer. Owing to their rarity, many clinicopathological features and treatment responses for each fusion variant are still largely unknown and require further investigation. RNA is the preferable template for the fusion gene screening, but deterioration of RNA in FFPE often makes the detection challenging.

A highly sensitive and specific real-time quantitative PCR for BRAF V600E/K mutation screening.

Mutations that lead to constitutive activation of key regulators in cellular processes are one of the most important drivers behind vigorous growth of cancer cells, and are thus prime targets in cancer treatment. BRAF V600E mutation transduces strong growth and survival signals for cancer cells, and is widely present in various types of cancers including lung cancer. A combination of BRAF inhibitor (dabrafenib) and MEK inhibitor (trametinib) has recently been approved and significantly improved the survival of patients with advanced NSCLC harboring BRAF V600E/K mutation.

[The regulation of ubiquitination in milk fat synthesis in bovine].

Ubiquitination signaling is the main pathway of protein degradation in eukaryotic cells. Ubiquitin-proteasome system degrades the ubiquitinated cytoplasmic proteins and lysosome pathway mainly degrades the ubiquitinated membrane proteins. Previous studies have shown that ubiquitination signaling plays a critical role in fatty acids synthesis.

Knock-down Sox5 suppresses porcine adipogenesis through BMP R-Smads signal pathway.

Adipogenesis, a differentiation process that transitions preadipocytes to adipocytes, is key to understanding the biology of fat accumulation and obesity. During this process, there many crucial transcription factors, such as PPARγ and the C/EBP family. Here we show a transcription factor in preadipocytes --- Sox5, that has a function in porcine adipogenesis.

[Regulation of VPS28 gene knockdown on the milk fat synthesis in Chinese Holstein dairy].

In a previous genome-wide association study on milk production traits in Chinese Holstein population, we discovered VPS28 gene was highly expressed in mammary gland tissue. Further, a -58C>T mutantion at the 5°-UTR of the gene was significantly associated with milk fat content traits. However, its regulation on milk fat content is still uncertain.

Differences between porcine longissimus thoracis and semitendinosus intramuscular fat content and the regulation of their preadipocytes during adipogenic differentiation.

Intramuscular fat (IMF) plays an important role in pork quality. However, differences in the adipogenic regulation of IMF content between pig longissimus thoracis (LT) and semitendinosus (ST) remain unclear. Here, we found that IMF content of 180-day-old pig LT was greater than that of pig ST.

Impact of putamen stroke on task context updating: Evidence from P300 brain waves.

According to the context updating theory, the oddball P300 component indexes brain activities underlying revision of the mental representation induced by incoming stimuli. It involves an attention-driven comparison process that evaluates the representation of the previous event in working memory. Delayed latencies have been reported for various types of stroke such as unilateral thalamic stroke.

miR-425-5p Inhibits Differentiation and Proliferation in Porcine Intramuscular Preadipocytes.

Intramuscular fat (IMF) content affects the tenderness, juiciness, and flavor of pork. An increasing number of studies are focusing on the functions of microRNAs (miRs) during porcine intramuscular preadipocyte development. Previous studies have proved that miR-425-5p was enriched in porcine skeletal muscles and played important roles in multiple physiological processes; however, its functions during intramuscular adipogenesis remain unclear.

miR-429 Inhibits Differentiation and Promotes Proliferation in Porcine Preadipocytes.

MicroRNAs (miRNAs) are crucial regulatory molecules for adipogenesis. They contribute to the controlling of proliferation and differentiation of preadipocytes. Previous studies revealed an important role of miR-429 in cell invasion, migration, and apoptosis.

Occurrence of Hexabromocyclododecane in soil and road dust from mixed-land-use areas of Shanghai, China, and its implications for human exposure.

Herein, the occurrence of three Hexabromocyclododecane (HBCDD) diastereoisomers in soil and road dust from the mixed-land-use areas in Shanghai was investigated. The total concentrations of HBCDDs (∑HBCDDs) in soil ranged from 0.30 to 249ngg(-1)dw, with a median level of 5.

Use of and Self-Perceived Need for Assistive Devices in Individuals with Disabilities in Taiwan.

Assistive devices (ADs) can help individuals with disabilities achieve greater independence, and it can enhance the quality of their lives. This study investigated the use of and self-perceived need for ADs in individuals with disabilities, and determined the influence of gender, age as well as type and degree of disability on the use of and self-perceived need for ADs. This descriptive study utilized a cross-sectional survey design with a convenience sample of participants.

Expression of Beclin Family Proteins Is Associated with Tumor Progression in Oral Cancer.

Background: Beclin 1 and Beclin 2 are autophagy-related proteins that show similar amino acid sequences and domain structures. Beclin 1 established the first connection between autophagy and cancer. However, the role of Beclin 2 in cancer is unclear.

Clinical characteristics and electrodiagnostic features in patients with carpal tunnel syndrome, double crush syndrome, and cervical radiculopathy.

Similar unilateral neck and upper limb symptoms are often due to various entrapment neuropathies; carpal tunnel syndrome (CTS) and cervical radiculopathy (CR) are common causes among them.

Metastatic carcinoma of the breast: a case with the unusual presentation of unilateral periorbital edema.

Background: Metastasis of mammary cancer involving the orbit is common, and it typically presents with enophthalmos and restrictions of ocular motility. We report a case of mammary cancer with the unusual presentation of unilateral periorbital edema only. The possible mechanisms of unilateral periorbital swelling are discussed.

Effects of wrist position and contraction on wrist flexors H-reflex, and its functional implications.

In order to determine whether joint position exerts a powerful influence on length-tension regulation in multiarticulate wrist flexors, three wrist positions (neutral, flexion and extension) and four levels of flexor contraction [0%, 10%, 20% and 30% maximum voluntary contraction (MVC)] were manipulated. There were significant differences in H-reflex amplitudes according to wrist positions and levels of flexor contraction. H-reflex increased linearly as a function of contraction in all three wrist positions.
