To investigate the signal transduction of osmotic stress, we examined hypertonicity-induced tyrosine phosphorylations in Chinese hamster ovary cells. Hyperosmosis elicited characteristic phosphotyrosine accumulation in at least 3 proteins (approximately 42, approximately 85, and approximately 120

ErbB receptor tyrosine kinase inhibitors (EGFR-TKI), gefitinib, erlotinib, icotinib and aftinib, which are approved as a frontline treatment for patients with non-small cell lung cancer (NSCLC) who have tumors harboring EGFR mutations in China. And osimertinib was approved in second line setting for

Protein tyrosine phosphatase non-receptor 22 (PTPN22) is involved in the negative regulation of T-cell responsiveness. Recently, it has been reported that a single nucleotide polymorphism (SNP), C1858T, in the gene PTPN22, encoding Arg620Trp in the lymphoid protein tyrosine phosphatase (LYP), is

Tyrosine hydroxylase deficiency is a rare neurotransmitter disorder affecting the rate-limiting step in catecholamine biosynthesis. There are about 40 cases reported worldwide. Here, we report the biochemical and molecular findings of eight unrelated Chinese patients with tyrosine hydroxylase

Piebaldism is a rare, autosomal dominant and congenital pigmentary disorder characterized by stable depigmentation of the skin and white forelock. Mutations in KIT or SNAI2 genes result in piebaldism. Most individuals with piebaldism have a family history of the disorder. Herein, we report a

Bruton's tyrosine kinase (BTK) is involved in B-cell development. Mutation of BTK results in X-linked agammaglobulinemia (XLA). BTK is expressed in most haemopoietic lineages except mature T cells and plasma cells. We identified six novel and two known mutations of BTK in 11 Chinese XLA patients

Immunostaining for epidermal growth factor receptor (EGFR), c-erbB-2, c-erbB-3, c-erbB-4, ER, and PR was performed in 107 cases of primary breast carcinomas from Anyang, China. The expression rates of EGFR, c-erbB-2, c-erbB-3 and c-erbB-4 in this series were 43.9%, 36%, 27%, and 45.8%, respectively,

By the use of recombinant technology, several stable Chinese hamster ovary (CHO) cell lines expressing human FVIII were established. Thrombin treatment and SDS-PAGE analysis of the purified recombinant FVIII (rFVIII) revealed a striking difference from plasma-derived FVIII (pFVIII). A 43-kDa

BACKGROUND DNA methyltransferase 3A (DNMT3A) mutations have been found in approximately 20% of adult acute myeloid leukemia (AML) patients and in 0% to 1.4% of children with AML, and the hotspots of mutations are mainly located in the catalytic methyltransferase domain, hereinto, mutation R882

Meningioma is a hormone-related intracranial tumor. Brain tumor samples were collected from 32 Chinese patients, 20 of whom had meningiomas. Estrogen receptors were present in 6 of 17 meningiomas, 1 hemangioblastoma, 1 gemistocytic astrocytoma, and 1 neurilemoma. Of the 26 samples assayed for

Tyrosine hydroxylase (TH) deficiency is a rare autosomal recessive inborn error of dopamine transmission, which the deficient gene is at the chromosome 11, also called'Segawa Syndrome'. TH converts tyrosine into L-DOPA, which is the direct precursor of catecholamine biosynthesis. TH deficiency

UNASSIGNED Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors and exhibit a high frequency of oncogenic KIT or PDGFRA mutations. Tyrosine kinase inhibitors (TKIs) have been mainly used in the treatment of GISTs bearing KIT/PDGFRA mutations. However, other mutation

Tyrosine kinase inhibitors (TKIs) have improved the overall survival of patients with gastrointestinal stromal tumors (GISTs), but their side effects can impact dose intensity and, consequently, the clinical benefit. To date, no guideline or consensus has been published on the TKI-associated adverse

BACKGROUND We assessed antibodies against low-density lipoprotein receptor-related protein 4 (LRP4-Ab) in a Chinese population with myasthenia gravis (MG). METHODS Serum samples from 116 patients and 80 controls were collected. Acetylcholine receptor antibodies(AChR-Ab) and muscle-specific receptor
