Cervical carcinoma is one of the highest causes of mortality in female and the number of patients is gradually increasing in the world. HeLa is a cervical carcinoma cell line and first established human immortalized cell line from cervical cancer patient. On the other hands, Heat shock transcription factor 1 (HSF1) is highly expressed in several cancer cells and tumors, and also involved in the malignancy. In order to investigate the role of HSF1 in cervical carcinoma, I established HeLa cell

Expressed caHSF1 significantly suppressed HeLa cell growth, whereas RgHSF1 did not show appreciable effects. G1 arrest occurred in the HeLa cells expressing caHSF1, and cyclinedependent kinase (CDK) inhibitors p16 and p21 were up-regulated. To our knowledge, this is the first report that HSF1 may have a role to suppress the cancer cell growth. But importantly, this study suggests HSF1 may have more complicated roles than expected.

Non-Hsp genes are essential for HSF1-mediated maintenance of whole body homeostasis

Naoki Hayashida
2015 Experimental animals  
Mammalian tissues are always exposed to diverse threats from pathological conditions and aging. Therefore, the molecular systems that protect the cells from these threats are indispensable for cell survival. A variety of diseases, including neurodegenerative diseases, cause intracellular damage and disturb homeostasis. Heat shock transcription factor 1 (HSF1) positively regulates heat shock protein (Hsp) and maintains the precise folding of proteins. Moreover, HSF1 induces the non-Hsp genes

However, whether these protective systems are similarly important to cellular defense in each tissue is still elusive. In this study, I compared polyglutamine (polyQ) protein aggregations/inclusion development in each tissue of WT-and HSF1KO-Huntington's disease (HD) mice, and examined the expression of the eight non-Hsp HSF1 target genes that have a strong suppressive effect on polyQ protein aggregation. Of these genes, Nfatc2, Pdzk3, Cryab, Csrp2, and Prame were detected in most tissues, but the other genes were not. Surprisingly, the obvious effect of HSF1 deficiency on the expression of these five genes was detected in only heart, spleen, and stomach. In addition, polyQ protein aggregations/ inclusion was not detected in any tissues of WT-HD and HSF1KO-HD mice, but higher level of preaggregative polyQ protein was detected in HSF1KO-HD tissues. These results indicate non-Hsp genes are indispensable for the maintenance of intracellular homeostasis in mammalian tissues, resulting in whole body homeostasis.

Upper gastrointestinal (GI) symptoms such as nausea and vomiting are common adverse events associated with selective serotonin reuptake inhibitors (SSRIs), and may result in discontinuation of drug therapy in patients with depressive disorder. Rikkunshi-to (formulation TJ-43), a traditional herbal medicine, has been reported to improve upper GI symptoms and comorbid depressive symptoms in patients with functional dyspepsia. The aim of the present study was to determine if TJ-43 reduces GI

Methods: Fifty patients with depressive disorder (19-78 years, mean age 40.2 years) were treated with FLV (n=25) or FLV in combination with TJ-43 (FLV+TJ-43) (n=25) for eight weeks. The following parameters of the two groups were compared: The number of patients who complained of adverse events and their symptoms; GI symptoms quality of life (QOL) score, assessed by the Gastrointestinal Symptom Rating Scale (GSRS), Japanese edition, before and two weeks after beginning treatment; and depressive symptoms assessed by the Self-Rating Depression Scale (SDS), before and 2, 4, and 8 weeks after beginning treatment. Results: The number of patients who complained of adverse events in the FLV+TJ-43 group (n=6) was significantly lower than the number complaining in the FLV group (n=13) (P < 0.05). The number of patients who complained of nausea was also lower in the FLV+TJ-43 group (n=3) than in the FLV group (n=9) (P < 0.05). By two weeks after treatment, GSRS scores had improved in -3the FLV+TJ-43 group, but not in the FLV group. SDS scores were not different between the two groups at any of the assessment points. Conclusions: This study suggests that Rikkunshi-to reduces FLV-induced adverse events, especially nausea, and improves QOL related to GI symptoms without affecting the antidepressant effect of FLV. -4 -

2013 FEBS Letters  
The febrile response is elicited by pyrogenic cytokines including IL-6 in response to microorganism infections and diseases in vertebrates. Mammalian HSF1, which senses elevations in temperature, negatively regulates the response by suppressing pyrogenic cytokine expression. We here showed that HSF3, an avian ortholog of mammalian HSF1, directly binds to and activates IL-6 during heat shock in chicken cells. Other components of the febrile response mechanism, such as IL-1b and ATF3, were also

A CASE OF GALLSTONE ILEUS

1985 The journal of the Japanese Practical Surgeon Society  
An obese 79-year-old diabetic woman was admitted with a history of intermittent abdominal pain and vomitting. Two years previously, she had been investigated in our hospital for cholecystolithiasis. Plain radiographs of abdomen with the patient supine revelaed air in the biliary tree and incomplete small-bowel obstruction. With the pre-operative diagnosis of gallstone ileus, laparotomy was performed, and 2.5cm calculus was removed from the jejunum. A large cholecysto-duodenal fistula was noted,

We analyzed 160 cases of gallstone ileus in Japan with special reference to treatment. We classified gallstone ileus into four types, according to the number, position of the stones before they enter the bowels. In type 1, there was no difference in the incidence of complications between the ileus operation group and the ileus operation plus radical operation group. In types 2 and 3, the incidence of complications was significantly lower in the ileus operation plus radical operation group than in the ileus operaton group. These results suggested that surgical removal of gallstones that obstruct the intestine will have good results in type 1 patients, but that additional radical surgery should be un dertaken primarily or secondarily in type 2 or 3 patients with gallstone ileus.
