CONTEXT Adrenocortical carcinomas (ACC) are a rare tumor type with a poor five-year survival rate and limited treatment options. OBJECTIVE Understanding of the molecular pathogenesis of this disease has been aided by genomic analyses highlighting alterations in TP53, WNT, and IGF signaling pathways. Further elucidation is needed to reveal therapeutically actionable targets in ACC. DESIGN In...

Adrenocortical carcinoma (ACC) despite being a rare endocrine malignancy arising from adrenal cortex carries poor prognosis. It is also challenging to diagnose these tumours preoperatively especially if it non-functioning tumour. As the rarity of disease pose great challenge in taking up statistically significant studies that would be needed improve management strategies and outcomes ACC, all r...

Adenoid cystic carcinoma (ACC) is a rare cancer with high potential for recurrence and metastasis. Efficacy of current treatment options, particularly for advanced disease, is very limited. Recent whole genome and exome sequencing has dramatically improved our understanding of ACC pathogenesis. A balanced translocation resulting in the MYB-NFIB fusion gene appears to be a fundamental signature ...

Aplasia cutis congenita (ACC) is a rare condition with an unclear pathogenic mechanism, although the condition has been suggested to occur as a result of the disrupted development or degeneration of skin in utero. ACC associated with fetus papyraceus has been described in numerous studies. Although there have been several reports of ACC, surgical treatment of ACC using the head as a site of don...

Although intact fruits of unripe cantaloupe (Cucumis melo L.) produce very little ethylene, a massive increase in ethylene production occurred in response to excision. The evidence indicates that this wound ethylene is produced from methionine via 1-aminocyclopropanecarboxylic acid (ACC) as in ripening fruits. Excision induced an increase in both ACC synthase and the enzyme converting ACC to et...

Acinar cell carcinoma (ACC) of the pancreas is a rare malignancy making up approximately 1% of pancreatic non-endocrine malignant tumors. The common finding on computed tomography is a solitary, well-defined, heterogenous hypodense mass with enhancing capsule. ACC is a highly cellular tumor with minimal stroma and a lack of stromal desmoplasia. The accurate diagnosis of ACC cannot typically be ...

Dopamine and serotonin (5-HT) in the nucleus accumbens (ACC) and ventral tegmental area of the mesoaccumbens reward pathways have been implicated in the mechanisms underlying development of alcohol dependence. We used a C57BL/6J mouse model with increased voluntary alcohol-drinking behavior by exposing the mice to alcohol vapor for 20 consecutive days. In the alcohol-exposed mice, the expressio...

The phenomenon of pioneer neurons has been known for almost a century, but so far we have little insights into mechanisms and molecules involved. Here, we study the formation of the Drosophila intersegmental motor nerve (ISN). We show that aCC/RP2 and U motor neurons grow together at the leading front of the ISN. Nevertheless, aCC/RP2 neurons are the pioneers, and U neurons are the followers, b...

Apples (Malus sylvestris Mill, cv Golden Delicious) were treated before harvest with aminoethoxyvinylglycine (AVG). AVG is presumed to reversibly inhibit 1-aminocyclopropane-1-carboxylic acid (ACC) activity, but not the formation of ACC synthase. AVG treatment effectively blocked initiation of autocatalytic ethylene production and ripening of harvested apples. Exogenous ethylene induced extract...

The thermoinhibition at 35 and 32 degrees C of pregermination ethylene production and germination in lettuce (Lactuca sativa L. cv Mesa 659) seeds was synergistically or additively alleviated by 0.05 millimolar kinetin (KIN) and 10 millimolar 1-aminocyclopropane-1-carboxylic acid (ACC). The synergistic effect of KIN + ACC on ethylene production and germination at 35 degrees C was inhibited by C...
