Arabidopsis thaliana TRANSPARENT TESTA GLABRA2 (TTG2) encodes a WRKY transcription factor and is expressed in young leaves, trichomes, seed coats, and root hairless cells. An examination of several trichome and root hair mutants indicates that MYB and bHLH genes regulate TTG2 expression. Two MYB binding sites in the TTG2 5' regulatory region act as cis(More)
CAPRICE (CPC), a small, R3-type Myb-like protein, is a positive regulator of root hair development in Arabidopsis. Cell-to-cell movement of CPC is important for the differentiation of epidermal cells into trichoblasts (root hair cells). CPC is transported from atrichoblasts (hairless cells), where it is expressed, to trichoblasts, and generally accumulates(More)
Early onset familial Alzheimer's disease with spastic paraparesis (FAD-SP) has been associated with mutations of the presenilin 1 gene (PSEN1). We report a pedigree of FAD-SP due to a novel missense mutation of PSEN1 (Y154N). The symptoms of the proband were characterized by presenile dementia in her 40s, preceded by spastic paraparesis in her 30s, whereas(More)
OBJECTIVE Tyrosine kinases and its receptors play important roles in growth, migration, and invasion of malignant cells. Among those, there are only few reports examining the expression pattern of Eph/ephrin signalling system in oesophageal carcinoma. The prognostic importance of ephrin-B2 ligand (EFNB2) and its receptor EphB4, and its correlation with(More)
Treatment of infantile acute lymphocytic leukemia (ALL) may cause failure to thrive and hypogonadism due to hypopituitarism induced by chemotherapy and whole-brain radiotherapy. We report the case of a 22-year-old girl with a genetic predisposition to pattern hair loss who developed inveterate diffuse alopecia. The patient had onset of ALL at 8 years old(More)
