Lysophosphatidic acid (LPA) is a lipid mediator with diverse effects on various cells. Here, we investigated the effects of LPA on human colon carcinoma DLD1 cells. Northern blot analysis revealed that DLD1 highly expressed LPA1/Edg-2 but showed only low expression of LPA2/Edg-4 and no expression of LPA3/Edg-7 at the mRNA level. Western blot analysis(More)
INTRODUCTION Lysophosphatidic acid (LPA) is a bioactive phospholipid with diverse effects on various cells. It interacts with at least three G-protein-coupled transmembrane receptors, namely LPA1, LPA2 and LPA3, whose expression in various tumours has not been fully characterized. In the present study we characterized the expression profile of LPA receptors(More)
Lysophosphatidic acid (LPA) and sphingosine-1-phosphate (S1P) are lysophospholipid mediators of diverse cellular processes important for cancer progression. S1P is produced by two sphingosine kinases, SphK1 and SphK2. Expression of SphK1 is elevated in many cancers. Here, we report that LPA markedly enhanced SphK1 mRNA and protein in gastric cancer MKN1(More)
BACKGROUND Japan has one of the highest five-year relative survival rates for colorectal cancer in the world, with its own traditions of perioperative care and a unique insurance system. The benefits of enhanced recovery after surgery (ERAS) protocols in the Japanese population have yet to be clarified. METHODS We evaluated 352 consecutive cases of(More)
Enhanced recovery after surgery (ERAS) protocols may reduce postoperative complications and the length of hospital stay. Studies of the effectiveness of ERAS should include not only doctor-reported outcomes, but also patient-reported outcomes, in order to better estimate their impact on recovery. However, patient-reported outcomes are not commonly reported.(More)
BACKGROUND Enhanced recovery after surgery (ERAS) protocols are now well-known to be useful for elective colorectal surgery, as they result in shorter hospital stays without adversely affecting morbidity. However, the efficacy and safety of ERAS protocols for patients with obstructive colorectal cancer have yet to be clarified. METHODS We evaluated 122(More)
Mieap, a p53-inducible protein, controls mitochondrial quality by repairing or eliminating unhealthy mitochondria. BNIP3 and NIX are critical mediators for the Mieap-regulated mitochondrial quality control. Mieap suppresses murine intestinal tumor via its mitochondrial quality control function. To explore the role of the Mieap-regulated mitochondria quality(More)
When obstructive colitis becomes fulminant, it is known as 'acute necrotizing colitis'. We report a rare case of acute necrotizing colitis due to sigmoid colon cancer, in which shock status occurred within ten hours of onset. A 79-year-old female with acute abdominal pain was transported to our hospital with acute shock. Abdominal enhanced computed(More)
BACKGROUND Ventriculoperitoneal shunt (VPS) placement is an established procedure for the treatment of hydrocephalus of diverse etiologies in children and adults. Abdominal cerebrospinal fluid pseudocyst, which is potentially life threatening, is a rare complication and usually occurs during childhood. However, with increasing longevity following successful(More)
The incidence of anastomotic recurrence after curative resection of colorectal cancer is relatively low compared to that of other types of recurrence, such as hepatic, lung and local recurrence. However, almost all cases of anastomotic recurrence of colorectal cancer occur within 3 years after surgery. We experienced a rare case of anastomotic recurrence in(More)
