Abstract
Eosinophilic enteritis (EoN) is associated with an eosinophilic infiltrate confined to the small intestine, but treatment options other than diet and corticosteroid therapy are scarce. There is only one report of the use of dupilumab for eosinophilic gastrointestinal disease, involving three pediatric patients. We report a case of successful induction of remission with dupilumab in a 53 year-old female patient with steroid-dependent EoN. The patient presented to the emergency room with uncontrollable abdominal pain and CT revealed a thickened ileal wall and small amount of ascites. Despite no abnormalities on endoscopy, histological examination revealed numerous eosinophilic infiltrates (> 100/HPF) and degranulation in the ileal lamina propria, diagnosing the patient with EoN. The patient achieved clinical remission with prednisolone, but EoN relapsed during tapering. Long-term steroid therapy was inappropriate due to mandibular osteomyelitis and osteoporosis, and she was switched to 9 mg budesonide, an intestine-soluble topical steroid without effect. Dupilumab administration resulted in resolution of abdominal pain, and remission was maintained after discontinuation of budesonide. Histological remission was confirmed 2 months after dupilumab administration. This is the first report of remission induced and maintained with dupilumab in an adult patient with EoN.

Abstract
Background Splenic rupture by diffuse large B-cell lymphoma (DLBCL), which usually progresses insidiously, is extremely rare. Case Presentation A 60-year-old man presented with paralysis in his lower left extremity. A magnetic resonance imaging suggested transverse myelitis. No lymphadenopathy or organomegaly was noted. Two months after remission, he was referred to the emergency department complaining of presyncope. He was in preshock due to splenic rupture, and underwent laparotomy after attempts of transcatheter arterial embolization. Splenomegaly, hepatomegaly, and disseminated enlarged lymph nodes were observed. Histological examinations of the resected spleen showed DLBCL. He died of multiple organ failure associated with intractable bleeding. His autopsy revealed diffuse systemic invasions of lymphoma cells except for the brain and spinal cord. Microscopically, the spinal cord showed macular incomplete necrosis and histiocytic infiltration, suggestive of hemophagocytic syndrome. Conclusion The progression of DLBCL in our case is drastically rapid. Undiagnosed transverse myelitis preceded the onset.

Abstract
Tumor lysis syndrome (TLS) is a life-threatening oncological emergency. Only one TLS case has been reported in patients with esophageal cancer. We report the case of a 61-year-old man with recurrent spontaneous TLS caused by esophageal cancer. He was admitted to our hospital to investigate low back pain and dysphagia. Endoscopy and computed tomography revealed esophageal cancer with multiple liver and bone metastases. He was diagnosed with laboratory TLS based on high serum uric acid and phosphorus. After intravenous fluids and allopurinol were administrated, chemotherapy with 5-fluorouracil and cisplatin was started the next day. Although he transiently developed clinical TLS, it was resolved with conservative treatment. However, mild renal dysfunction was prolonged and cisplatin was reduced in the second course. As a consequence, recurrence of spontaous TLS (sTLS) was induced at the end of the course. In the third course, docetaxel was added to the regimen, and since then the patient have not develop sTLS. To the best of our knowledge, this is the first report regarding recurrent sTLS developed on the basis of solid tumors and was successfully controlled by chemotherapy. Although TLS complications are rare in esophageal cancer, early diagnosis and the adjustment of regimen resulted in stable chemotherapy.

Abstract
BACKGROUND AND AIMS Ulcerative colitis [UC] is a chronic inflammatory disease of the colon with an intractable course. Although the goal of UC therapy is to achieve mucosal healing, the pathogenesis of mucosal injury caused by chronic inflammation remains unknown. We therefore aim to elucidate molecular mechanisms of mucosal injury by establishing in vitro and in vivo humanised UC-mimicking models. METHODS An in vitro model using human colon organoids was established by 60 weeks of inflammatory stimulation. The key gene for mucosal injury caused by long-term inflammation was identified by microarray analysis. An in vivo model was established by xenotransplantation of organoids into mouse colonic mucosa. RESULTS An in vitro model demonstrated that long-term inflammation induced irrecoverable changes in organoids: inflammatory response and apoptosis with oxidative stress and suppression of cell viability. This model also mimicked organoids derived from patients with UC at the gene expression and phenotype levels. Microarray analysis revealed Schlafen11 [SLFN11] was irreversibly induced by long-term inflammation. Consistently, SLFN11 was highly expressed in UC mucosa but absent in normal mucosa. The knockdown of SLFN11 [SLFN11-KD] suppressed apoptosis of intestinal epithelial cells [IECs] induced by inflammation. Moreover, SLFN11-KD improved the take rates of xenotransplantation and induced the regenerative changes of crypts observed in patients with UC in remission. CONCLUSIONS In vitro and in vivo UC-mimicking models were uniquely established using human colonic organoids. They revealed that SLFN11 is significant for mucosal injury in UC, and demonstrated its potential as a novel target for mucosal regeneration.

Abstract
Intestinal ischemia is a rare complication of Takayasu arteritis (TAK), which often requires colectomy. We report the case of a 27 year-old man with ulcerative colitis (UC), who was admitted to our hospital due to abdominal pain. Computed tomography revealed an edematous wall of the ascending colon with ascites and a thickened aortic wall with mild stenosis of the superior mesenteric artery (SMA), suggesting large vessel vasculitis, especially TAK. Colonoscopy revealed acute ischemic colitis associated with mild stenosis of the SMA caused by TAK, but there was no worsening of UC. The patient was successfully treated with conservative therapy.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease that causes chronic inflammation in the colon. 5-aminosalicylic acid and immunosuppressive medications such as corticosteroids, immunomodulators, and biologic agents are used to treat these patients. However, patients with UC who receive immunosuppressive medications may be at risk for certain opportunistic infections. Epstein-Barr virus (EBV) is one of those opportunistic infections, and its pathogenic role has been implicated in refractory UC, but its pathogenicity should be further investigated. Here, we report a surgical case of refractory UC that demonstrated a serologically post-infected pattern of EBV at admission but that later had a high load of EBV in both the peripheral blood and colonic mucosa. These findings suggest that EBV may have been reactivated in the colon, after which it damaged the colonic mucosa and aggravated inflammation in this patient with UC. Thus, EBV might lead to severity and a refractory response against corticosteroids and anti-TNFα agents, necessitating emergency surgery. Viral surveillance for EBV in patients with refractory UC may facilitate understanding of the patient's pathophysiology and predicting response to medications, and the development of antiviral intervention for those patients may improve their prognosis.

Abstract
BACKGROUND & AIMS There are intra- and interobserver variations in endoscopic assessment of ulcerative colitis (UC) and biopsies are often collected for histologic evaluation. We sought to develop a deep neural network system for consistent, objective, and real-time analysis of endoscopic images from patients with UC. METHODS We constructed the deep neural network for evaluation of UC (DNUC) algorithm using 40,758 images of colonoscopies and 6885 biopsy results from 2012 patients with UC who underwent colonoscopy from January 2014 through March 2018 at a single center in Japan (the training set). We validated the accuracy of the DNUC algorithm in a prospective study of 875 patients with UC who underwent colonoscopy from April 2018 through April 2019, with 4187 endoscopic images and 4104 biopsy specimens. Endoscopic remission was defined as a UC endoscopic index of severity score of 0; histologic remission was defined as a Geboes score of 3 points or less. RESULTS In the prospective study, the DNUC identified patients with endoscopic remission with 90.1% accuracy (95% confidence interval [CI] 89.2%-90.9%) and a kappa coefficient of 0.798 (95% CI 0.780-0.814), using findings reported by endoscopists as the reference standard. The intraclass correlation coefficient between the DNUC and the endoscopists for UC endoscopic index of severity scoring was 0.917 (95% CI 0.911-0.921). The DNUC identified patients in histologic remission with 92.9% accuracy (95% CI 92.1%-93.7%); the kappa coefficient between the DNUC and the biopsy result was 0.859 (95% CI 0.841-0.875). CONCLUSIONS We developed a deep neural network for evaluation of endoscopic images from patients with UC that identified those in endoscopic remission with 90.1% accuracy and histologic remission with 92.9% accuracy. The DNUC can therefore identify patients in remission without the need for mucosal biopsy collection and analysis. Trial number: UMIN000031430.

Abstract
Aims Lymph node metastasis (LNM) has not been found in more than 85% of patients with early invasive colorectal adenocarcinoma (T1‐CRAC) who undergo surgery after therapeutic endoscopy due to the risk for LNM. Better histological risk assessment for LNM of endoscopically resected T1‐CRAC is important to avoid unnecessary additional surgery. Methods and results We evaluated cancer gland rupture (CGR), i.e. cancer glands with a discontinuous epithelial lining, at the invasive front, as a potential risk factor for LNM by histological examination of differentiated T1‐CRAC from 217 patients who underwent surgery with or without therapeutic endoscopy. CGR was represented by C‐shaped neoplastic glands with a variable inflammatory or stromal reaction, and was occasionally accompanied by mucus lake or abscess formation. CGR was observed in 168 (77%) cases, including all 20 cases with LNM, and the odds ratio of LNM was higher for CGR than for deep invasion (depth of submucosal invasion ≥1000 μm). All cases with LNM were found among 148 cases with deep invasion and positive CGR, whereas no LNM was detected in 29 cases with deep invasion and negative CGR, regardless of vascular invasion or tumour budding. In the 148 cases, LNM was detected in 18 (19%) of 93 cases with positive vascular invasion or high‐grade tumour budding, and in two (4%) of 55 cases without either. Conclusions Our findings suggest that CGR is an easily applied and objective histological finding for predicting LNM that could be useful for assessing the risk for LNM of endoscopically resected T1‐CRAC with deep invasion.

Abstract
BACKGROUND AND AIM The treat-to-target strategy has emerged in ulcerative colitis management. Mucosal healing is the best target, albeit not in induction therapy of acute diseases as clinical conditions vary over a short duration. To determine the targets during induction therapy for acute ulcerative colitis, we identified markers to predict mucosal healing at 3 and 12 months of initiating the induction therapy. METHODS This single-center prospective observational study enrolling 61 adult patients hospitalized for disease exacerbation collected the partial Mayo scores, ulcerative colitis endoscopic index of severity, fecal markers, and laboratory data (0 day, 2 weeks, and 3 and 12 months) of initiating induction therapy. RESULTS At 2 weeks, patients with mucosal healing at 3 months had had lower partial Mayo and ulcerative colitis endoscopic index of severity scores and higher white blood cell count and total cholesterol than those without mucosal healing. At 3 months, patients with mucosal healing at 12 months had had lower partial Mayo and ulcerative colitis endoscopic index of severity scores than those without mucosal healing. A kinetic analysis demonstrated a difference in the partial Mayo scores and total cholesterol and albumin levels at 2 weeks and in the ulcerative colitis endoscopic index of severity, fecal calprotectin, and fecal immunochemical tests at 3 months between patients who achieved mucosal healing at 12 months and those who did not. CONCLUSIONS Partial Mayo scores and total cholesterol levels act as short-term therapeutic targets during induction therapy in patients with acute ulcerative colitis. Mucosal healing at 3 months correlates to longer time mucosal healing.

Abstract
Porphyromonas gingivalis and Tannerella forsythia have been thought to be associated with periodontitis; however comprehensive histopathological localization of bacteria in affected human periodontal tissues is not well documented. In the present study, we examined formalin-fixed paraffin-embedded gingival and subgingival granulation tissues from 71 patients with chronic periodontitis and 11 patients with aggressive periodontitis, using immunohistochemistry with novel monoclonal antibodies specific to P. gingivalis or T. forsythia, together with quantitative real-time polymerase chain reaction for each bacterial DNA. Immunohistochemisty revealed both bacterial species extracellularly, as aggregates or within bacterial plaque, and intracellularly in stromal inflammatory cells, squamous epithelium, and capillary endothelium of granulation tissue. Combined analysis with the results from polymerase chain reaction suggested that localization and density of T. forsythia is closely associated with those of P. gingivalis, and that bacterial density is a factor responsible for the cell-invasiveness and tissue-invasiveness of these periodontal bacteria. Detection of these bacteria in the capillary endothelium in some samples suggested possible bacterial translocation into the systemic circulation from inflamed gingival and subgingival granulation tissues. Immunohistochemistry with the novel antibodies showed high specificity and sensitivity, and can be used to locate these periodontal bacteria in routinely-used formalin-fixed paraffin-embedded human tissue sections from systemic locations.

Abstract
RATIONALE The small intestine (SI) does not commonly harbor cancer but is occasionally involved by metastatic cancer from other organs. To manage SI cancer appropriately, surveillance for primary origin outside the SI is essential. PATIENT CONCERNS This study presents a 54-year-old Thai man diagnosed with SI obstruction which required laparoscopy- assisted partial ileal resection. DIAGNOSES On the basis of the expression pattern of cytokeratins (CKs) and mucins (MUCs) in the resected SI adenocarcinoma, we suspected this was metastasized from the pancreatobiliary tract. Imaging studies revealed a hepatic segmental atrophy with an occlusion of the posterior segmental blanch of the portal vein without any contrast-enhanced lesions in the liver. Pathology of the liver biopsy revealed intrahepatic cholangiocarcinoma (ICC) with the same expression pattern of CKs and MUCs as the SI adenocarcinoma. INTERVENTIONS Systemic chemotherapy (gemcitabine and cisplatin) was initiated. OUTCOMES Despite of the chemotherapy for 20 months, he died of ICC. LESSONS This is the first case of SI obstruction caused by the metastasis of ICC. We demonstrate that immunohistochemical staining of CKs and MUCs discriminate between primary and metastatic SI cancer and predict its primary origin outside the SI. This case also suggests that a hepatic segmental atrophy with portal vein occlusion would be an atypical but important finding to diagnose ICC.

Abstract
Background Propionibacterium acnes is thought to be a causative agent of sarcoidosis. Patients with sarcoidosis have circulating immune complexes. We attempted to detect P. acnes-derived immune complexes in sarcoid lesions. Methods We evaluated formalin-fixed and paraffin-embedded lymph node samples from 38 sarcoidosis patients and 90 non-sarcoidosis patients (27 patients with necrotizing lymphadenitis, 28 patients with reactive lymphadenitis, 16 patients with colon cancer, 19 patients with gastric cancer) by immunohistochemistry using anti-human immunoglobulins (IgG, IgA, and IgM) and complement (C1q and C3c) antibodies, and a P. acnes-specific monoclonal antibody (PAB antibody) that reacts with the membrane-bound lipoteichoic acid of P. acnes. Results Small round bodies (SRBs) bound to IgA, IgM, or IgG were detected in sinus macrophages, in 32 (84%), 32 (84%), or 11 (29%) sarcoid samples, respectively, and in 19 (21%), 26 (29%), or no (0%) control samples, respectively. Some of these insoluble immune complexes (IICs) also bound to C1q and C3c. We developed a microwave treatment followed by brief trypsin digestion (MT treatment) to detect PAB-reactive SRBs bound to immunoglobulins (IIC-forming P. acnes). MT treatment revealed abundant IIC-forming P. acnes in most (89%) of the sarcoid samples and sparse distribution in some (20%) of the control samples with lymphadenitis, but no IIC-forming P. acnes was detected in control samples without inflammation. IIC-forming P. acnes were mostly bound to both IgA and IgM. The PAB-reactive antigen and immunoglobulins were both located at the peripheral rim of the IIC-forming P. acnes. Conventional electron microscopy identified many SRBs (0.5–2.0 μm diameter) in sinus macrophages of sarcoid lymph nodes with many IIC-forming P. acnes, some of which were in phagolysosomes with a degraded and lamellar appearance. Conclusions P. acnes-derived IICs in sinus macrophages were frequent and abundant in sarcoid lymph nodes, suggesting a potential etiologic link between sarcoidosis and this commensal bacterium.

Abstract
BACKGROUND AND AIM Ulcerative colitis (UC) is a chronic inflammatory disease of the colon with an intractable, recurrent course. Although the goal of UC therapy has recently been to target mucosal healing, the molecular mechanism of mucosal healing remains unknown. In this study, we aimed to elucidate the molecular dynamics related to the proliferation and differentiation of intestinal epithelial cells during cytapheresis therapy in a short duration. METHODS Endoscopy was performed in 26 patients with UC in multicentre hospitals, and biopsy specimens were collected from the rectum before and within two weeks after leukocytapheresis (LCAP). The expression of representative proteins in intestinal epithelial cells and pathological findings was compared before and after LCAP. RESULTS The expression of caudal type homeobox 2 (CDX2) and a hes family bHLH transcription factor 1(HES1) markedly increased after LCAP. Patients with endoscopic improvement after LCAP showed the expression of CDX2 before LCAP. Moreover, the number of goblet cells significantly increased after LCAP. Patients without endoscopic improvement after LCAP did not show the expression of CDX2 before LCAP. However, the expression of CDX2 markedly increased after LCAP. CONCLUSION This study suggests that cytapheresis might induce CDX2 expression without affecting the cell proliferation, thus resulting in mucosal healing with goblet cell restoration.

Abstract
BACKGROUND AND AIM Takayasu arteritis (TA) is occasionally complicated with inflammatory bowel disease (IBD). This study assessed the endoscopic and genetic features of IBD complicated with TA (IBD-TA). METHODS This study retrospectively reviewed the clinical charts of 142 TA patients (14 men and 128 women; median age 48.5 years [range, 18-97 years]). Human lymphocyte antigen (HLA) types and a single-nucleotide polymorphism rs6871626 in the IL12B gene were assessed in 101 and 81 patients with TA, respectively. RESULTS Inflammatory bowel disease was diagnosed in 13 (9.2%) of the 142 patients. The endoscopic features of IBD-TA at initial diagnosis (n = 8) showed discontinuous and focal mucosal inflammations (n = 7, 87.5%), and only one case was diagnosed as ulcerative colitis (UC) at the first colonoscopy. In the genetic comparison of HLA class I between TA patients with IBD and those without IBD, HLA-B*52:01 and C*12:02 were more frequent in the IBD-TA group (P = 0.001 and P = 0.009, respectively). Meanwhile, HLA-DRB-1*15:02, DQA-1*01:03, DQB-1*06:01, and DPB-1*09:01 as HLA class II were positively associated with IBD-TA (P = 0.004, P = 0.019, P = 0.019, and P = 0.002, respectively). IL12B rs6871626 did not show an association with IBD-TA compared with that with TA without IBD. CONCLUSIONS The endoscopic findings of IBD-TA at initial diagnosis were atypical for UC or Crohn's disease. IBD-TA possessed the HLA haplotype, which had a susceptible effect on UC.

Abstract
A 58-year-old woman was referred to our hospital for Cushingoid features and diagnosed as adrenal Cushing's syndrome due to a right adrenocortical mass (60 × 55 mm). The mass was composed of three different tumors; the first one was homogeneously lipid-poor neoplasm measuring 20 × 13 mm located at the most dorsal region, the second one was heterogeneous and lipid-rich tumor containing multiple foci of calcification measuring 50 × 32 mm located at the central region, and the last one was heterogeneous harboring dilated and tortuous vessels and lipid-poor one measuring 35 × 18 mm at the most ventral region of the adrenal gland. A right adrenalectomy was subsequently performed by open surgery. Macroscopic and microscopic analyses revealed that all three tumors were adrenocortical adenomas; the first one represents a pigmented adrenocortical adenoma, the second one adrenocortical adenoma associated with degeneration, and the third one adrenocortical adenoma harboring extensive degeneration. Immunohistochemical analysis of the steroidogenic enzymes also revealed that all of the tumors had the capacity of synthesizing cortisol. This is a very rare case of Cushing's syndrome caused by multiple adrenocortical adenomas including a pigmented adenoma. Immunohistochemical analysis of steroidogenic enzymes contributed to understanding of steroidogenesis in each of these three different adrenocortical adenomas in this case.

Abstract
The effectiveness of bortezomib treatment for multiple myeloma (MM) is well established. However, the protocol by which maintenance therapy using bortezomib should be continued for myeloma patients requiring regular hemodialysis remains to be established. We herein report a case of MM with severe renal insufficiency requiring hemodialysis for nearly 30 months which was finally withdrawn from renal replacement therapy during monthly maintenance treatment with bortezomib and dexamethasone for two years. The details of this case are essential for establishing clinical guidelines for applying intermittent low-frequency bortezomib therapy in dialysis-dependent myeloma patients.

Abstract
The object of this study was to analyze the pathology of collateral vessels newly induced by indirect bypass surgery for moyamoya disease (MMD). An autopsy analysis was conducted on a 39-year-old woman with MMD who had died of a brainstem infarction. The patient had undergone bilateral indirect bypass surgeries 22 years earlier. Sufficient revascularization via bilateral external carotid arterial systems was confirmed by cerebral angiography before her death. Macroscopic observation of the operative areas revealed countless meandering vessels on the internal surface of the dura mater connected with small vessels on the brain surface and in the subpial brain tissue. Notably, microscopic analysis of these vessels revealed the characteristic 3-layer structure of an arterial wall. This autopsy analysis was the first to confirm that indirect bypass surgery had induced the formation of a new arterial network (arteriogenesis) and that this network had been maintained for more than 20 years to compensate for the chronic cerebral ischemia caused by the MMD.

Abstract
Patients with inflammatory bowel disease (IBD) have an increased risk of developing colitis-associated colorectal cancer (CAC). CAC cells often develop chemoresistance, resulting in a poorer prognosis than that of sporadic colorectal cancer (CRC). The mechanism by which CAC enhances malignant potential remains unknown. We have previously reported that the proteasomal degradation of the transcription factor Atonal homolog 1 (Atoh1) protein results in the non-mucinous form of CRC. It also remains unknown whether Atoh1 protein is expressed in CAC. Therefore, in the present study, we investigated whether Atoh1 protein stabilizes in CAC. Consequently, the treatment with TNF-α stabilized Atoh1 protein through the inactivation of GSK-3β via Akt, resulting in the mucinous form of CRC cell lines. Atoh1 protein also enriched cancer stem cells with upregulated Lgr5 expression and cells in G0/G1 cell cycle phase, resulting in both the chemoresistance to 5-fluorouracil and oxaliplatin and the promotion of cell migration. Immunofluorescence of the human mucinous CAC specimens showed the accumulation of NF-κB p65 at nuclei with the expression of Atoh1 in mucinous cancer. In conclusion, the inflammation associated with carcinogenesis may preserve the differentiation system of intestinal epithelial cell (IEC), resulting in the acquisition of both the mucinous phenotype and high malignant potential associated with the enrichment of cancer stem cell.

Abstract
Sarcoidosis likely results from the exposure of a genetically susceptible subject to an environmental agent, possibly an infectious one. Mycobacterial and propionibacterial organisms are the most commonly implicated potential etiologic agents. Propionibacterium acnes is the only microorganism, however, found in sarcoid lesions by bacterial culture. To evaluate the pathogenic role of this indigenous bacterium, we screened for the bacterium in sarcoid and non-sarcoid tissues using immunohistochemical methods with novel P. acnes-specific monoclonal antibodies that react with cell-membrane-bound lipoteichoic acid (PAB antibody) and ribosome-bound trigger-factor protein (TIG antibody). We examined formalin-fixed and paraffin-embedded samples of lungs and lymph nodes from 196 patients with sarcoidosis, and corresponding control samples from 275 patients with non-sarcoidosis diseases. The samples were mostly from Japanese patients, with 64 lymph node samples from German patients. Immunohistochemistry with PAB antibody revealed small round bodies within sarcoid granulomas in 20/27 (74%) video-assisted thoracic surgery lung samples, 24/50 (48%) transbronchial lung biopsy samples, 71/81 (88%) Japanese lymph node samples, and 34/38 (89%) German lymph node samples. PAB antibody did not react with non-sarcoid granulomas in any of the 45 tuberculosis samples or the 34 samples with sarcoid reaction. In nongranulomatous areas, small round bodies detected by PAB antibody were found in alveolar macrophages of lungs and paracortical macrophages of lymph nodes from many sarcoid and some non-sarcoid patients. Large-spheroidal acid-fast bodies, Hamazaki-Wesenberg bodies, which were found in 50% of sarcoid and 15% of non-sarcoid lymph node samples, reacted with both PAB and TIG antibodies. Electron microscopy revealed that these Hamazaki-Wesenberg bodies had a single bacterial structure and lacked a cell wall with occasional protrusions from the body. The high frequency and specificity of P. acnes, detected by PAB antibody within sarcoid granulomas, indicates that this indigenous bacterium might be the cause of granuloma formation in many sarcoid patients.

Abstract
Expression of mRNA encoding MFG-E8, a milk fat-associated glycoprotein was investigated in mouse mammary gland. Two forms of mRNA, long and short variants, were shown to be expressed in the mammary tissue by RT-PCR analysis. Sequence analyses of these two variants and an isolated MFG-E8 gene segment indicated that the long and short mRNA variants resulted from an alternative splicing of a single pre-mRNA through in-flame inclusion and skipping of one exon, which encodes a proline/threonine (Pro/Thr)-rich domain. The long variant was expressed predominantly in mammary gland and the expression level was remarkably increased at late gestation and kept high during lactation. On the contrary, the short variant was detected ubiquitously in various tissues and its expression in the mammary gland was rather decreased in a lactation dependent manner. Expression of the long variant was also detected in a mouse mammary epithelial cell line, COMMA-1D, and enhanced by incubation with lactogenic hormones. Glycosylation inhibition analyses using tunicamycin and alpha-benzyl-GalNAc were conducted with COS7 cells transfected with plasmids expressing each mRNA variant, demonstrating that a fully glycosylated product of the long mRNA variant was not only N-glycosylated but also multiply O-glycosylated, whereas a product of the short one had only N-glycan(s). These results suggest that the alternative splicing plays a critical role for the mammary-specific and lactation-dependent expression of the MFG-E8 isoform and that the multiply O-glycosylated Pro/Thr-rich domain of this isoform is functionally important for formation of milk fat globules in mammary epithelial cells.

Abstract
The expression of mouse milk fat globule membrane (MFGM) glycoproteins, MFG-E8, butyrophilin, CD36 was analyzed by Northern blot analyses. MFG-E8 and butyrophilin mRNAs were specifically detected in the mammary gland of lactating mice, whereas CD36 mRNA was detected in the heart and lung as well as in the mammary gland of lactating mice. The mRNAs of the three MFGM glycoproteins accumulated at mid-lactation were about 2-10-times as much as those of the early and late gestation stages, whereas beta-casein mRNA accumulation was dramatically increased; the mRNA at mid-lactation was no less than 40-times as much as that before lactation. In mouse mammary epithelial cell lines, HC11 and COMMA-1D, only a slight or almost no enhancement for the expression of MFG-E8, butyrophilin and CD36 mRNAs was induced simply by the treatment with the lactogenic hormones such as prolactin, insulin and dexamethasone, whereas the beta-casein mRNA expression was remarkably enhanced only by that treatment. Furthermore, while the beta-casein protein was constantly detected in milk throughout the lactation stage, the content of MFG-E8 and butyrophilin proteins increased during the lactation with an increase in the milk fat content. These results suggest that the stage-specific expression of milk fat globule membrane glycoproteins in mammary epithelial cells is regulated in a similar but not necessarily identical mechanism to that of a major milk protein, beta-casein.

Abstract
BACKGROUND/AIMS Hepatitis C virus (HCV) genome heterogeneity by sequence analysis in association with interferon (IFN) inefficacy has been reported. This study was performed to establish a convenient method for detecting the HCV quasispecies complexity and to determine the correlation between the complexity and the responsiveness to IFN therapy in patients with chronic hepatitis C. METHODS The quasispecies complexity of HCV hypervariable region 1 in patients treated with IFN-alpha was analyzed by polymerase chain reaction-mediated single-strand conformation polymorphism (SSCP). RESULTS Seven of 25 patients (28%) with low complexity (SSCP band number of < or = 2) were HCV RNA negative after treatment, whereas in 24 patients with high complexity (SSCP band number of > or = 3), the response to IFN was almost insignificant because only 1 patient (4.5%) remained HCV RNA negative after treatment (P < 0.05). Among type 1b patients, IFN therapy was only effective for patients with low amounts of HCV RNA (< or = 10(7.5) copies/mL serum) and low complexity. In contrast, most type 2a patients tended to respond to the therapy with exceptions being those with high amounts of HCV RNA and high complexity. CONCLUSIONS The complexity of the hypervariable region 1 quasispecies may be a factor for predicting IFN inefficacy in patients with chronic hepatitis C.

Abstract
The effects of enhancement of enzymatic activity by heating at 56 degrees C or by limited treatment with dimethylsulfoxide, trypsin and cathepsin D on two forms (Mr = 50 kDa and 72 kDa) of human epidermal transglutaminase were studied by immunoblots using rabbit antihuman epidermal transglutaminase. Both 50 kDa and 72 kDa transglutaminase bands were detected without any alteration in the mobility of the transglutaminase bands during activation induced by heating at 56 degrees C or by pretreatment with dimethylsulfoxide. With a preincubation period longer than 60 min, the trypsin pretreated sample showed progressive disappearance of the 72 kDa transglutaminase band in conjunction with the loss of transglutaminase activity. On the other hand, samples preincubated with cathepsin D showed a complete disappearance of the 50 kDa band after 180 min. These studies suggest the different forms of human epidermal transglutaminase may regulate enzyme activity each other during normal epidermal differentiation.

Abstract
Extracellular polysaccharides synthesized by Azospirillum brasilense and A. lipoferum were shown on agar plates and liquid flocculating cultures. The six strains used in this work expressed a mucoid phenotype, yielding positive calcofluor fluorescence under UV light. The calcofluor-binding polysaccharides were distributed between the capsular and exopolysaccharide fractions, suggesting exocellular localization. No calcofluor fluorescence was observed in residual cells after separation of the capsular and exopolysaccharide fractions. Cellulose content was significantly higher in flocculating than in nonflocculating cultures. Failure to induce flocculation by addition of cellulose (100 mg/ml) to nonflocculating cultures, together with the sensitivity of flocs to cellulase digestion, suggested that cellulose is involved in maintenance of floc stability. Different A. brasilense and A. lipoferum strains bound to a wheat lectin (fluorescein isothiocyanate-wheat germ agglutinin), indicating the occurrence of specific sugar-bearing receptors for wheat germ agglutinin on the cell surface. The biochemical specificity of the reaction was shown by hapten inhibition with N-acetyl-D-glucosamine. All six strains failed to recognize fluorescein isothiocyanate-soybean seed lectin under our experimental conditions. We conclude that azospirilla produce exocellular polysaccharides with calcofluor- and lectin-binding properties.

Abstract
A murine monoclonal antibody (ECS-1) was prepared from BALB/c mice immunized with trypsinized cultured human foreskin keratinocytes. The antibody showed a pattern suggestive of intercellular staining on the nucleated layers of normal human epidermis, adult palm, mouse lip epidermis, and cultured human keratinocytes. ECS-1 stained human fetal skin by 9 weeks estimated gestational age. ECS-1 reacted with a 35 kD protein extracted from neonatal foreskin epidermis and cultured human keratinocytes. The protein required Nonidet P-40 or sodium dodecyl sulfate and mercaptoethanol for solubilization. ECS-1 induced epidermal cell detachment which was enhanced by complement. ECS-1 shares characteristics with human pemphigus antibodies.

Abstract
The authors investigated the influence of culture medium pH and various kinds of protease inhibitors on the growth of Candida albicans when cultivated in liquid medium containing human stratum corneum (HSC) as the nitrogen source. Rapid growth of C. albicans was observed with weakly acidic media, particularly at pH 4.0. From among the various kinds of protease inhibitors added to the media at pH 4.0, pepstatin, a carboxyl protease inhibitor, most strongly inhibited the growth of C. albicans dependent upon its concentration. The antifungal effect of pepstatin was not fungicidal, but was nevertheless effective even at a very low concentration of 0.01 microgram/ml. This inhibitory effect of pepstatin was considerably stronger than that of the well-known antifungal agent, clotrimazole. Pepstatin is a specific inhibitor of keratinolytic proteinase (KPase) from C. albicans; it belongs to the carboxyl proteinases group and has an optimum pH at 4.0. Pepstatin showed a strong antifungal effect, possibly through KPase inhibition, in biologic (HSC) medium that was similar to that encountered in vivo. Our results suggest that KPase may play an important role in the growth of C. albicans and that pepstatin has the possibility of being used as a new type of antifungal agent.

Abstract
Human stratum corneum was extracted in Tris-HCl containing EDTA and phenylmethylsulfonyl fluoride, separated on sodium dodecyl sulfate-polyacrylamide gel electrophoresis, transblotted to nitrocellulose papers and reacted with rabbit antihuman epidermal transglutaminase (ETG) antibody. Protein-bound antibody was detected with a multistep peroxidase procedure. Proteins with a molecular weight of 50,000 (50kDa) and 72,000 daltons (72kDa) were stained when anti-ETG was used and not when second antibody alone or sera from nonimmunized animals were used. When ETG was treated with trypsin or organic solvents, there was no alteration in the mobility of the 50kDa ETG band, but there was complete disappearance of the 72kDa band. Antibody that bound 72kDa protein, when eluted from the blot, reacted with both 50kDa and 72kDa proteins; similarly, antibody that bound to the 50kDa protein, when eluted from the blot, reacted with both the 50kDa and 72kDa proteins. Partially purified 72kDa ETG activity was increased (3 to 16 times control levels) after heating at 56 degrees C in the presence of calcium and dithiothreitol or by treatment with trypsin. These studies, in conjunction with the previous studies of ETG activation, are consistent with there being two forms of ETG. The different forms may play a role in regulating enzyme activity.

Abstract
Extensive morphological and biochemical studies were carried out on two sibling cases of ichthyosis linearis circumflexa. The condition was found to be similar to psoriasis in the following ways: effectiveness of PUVA therapy, psoriatic changes on light and electron microscopy, high urinary polyamine levels, elevation of several enzyme activities in the scales, and a remarkable change in keratin molecules. These results may reflect an increased epidermal proliferation with a reduced epidermal transit time, as occurs in psoriasis.

Abstract
Candida albicans was able to produce a keratinolytic proteinase (KPase) when cultivated in a medium containing human stratum corneum as a nitrogen source. The KPase was purified to 108.5-fold by ion-exchange chromatography and gel filtration. The molecular weight of the enzyme was estimated to be 42,000 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and gel filtration through Sephacryl S-200, while the isoelectric point was determined to be at pH 4.5. The enzyme had an optimum pH of 4.0 and was "inactive" below pH 2.5 and above pH 6.0. The activity of KPase after preincubation at various temperatures was stable up to 50 degrees C. The keratinolytic activity was not affected by the addition of nonionic detergents and divalent cations. The enzyme was a glycoprotein and contained a high content of aspartic acid residues (172/1000). Pepstatin and chymostatin inhibited the activity in a dose-dependent manner; however, neither the other group specific inhibitors tested nor the pepsin specific inhibitors, DAN or EPNP, showed any effect on the enzyme. From these inhibitory profiles, this enzyme was determined to be a carboxyl proteinase such as cathepsin D. Among the various substrates for proteolytic enzymes, KPase digested human stratum corneum as much as albumin and hemoglobin. In the three fractions (water soluble, keratin filamentous, and membranous) prepared from human stratum corneum, the keratin filamentous fraction was more susceptible to degradation by KPase than the other two fractions were. KPase also digested much less human fingernail (13%) than human stratum corneum, but did not show any signs of there being any digestion of human scalp hair. These studies suggest that KPase from C. albicans may play an important role in superficial infection by affecting the human stratum corneum of the skin and nail.

Abstract
The activity of crude human epidermal transglutaminase was enhanced remarkably following 24 hr preincubation at low pH (pH 4.5), whereas the pure human epidermal transglutaminase did not show enhancement of enzyme activity at low pHs. Preincubation of pure transglutaminase with rat liver lysosomal fractions (100 microgram/ml) caused a time-dependent enhancement of activity at pH 4.5, up to 4.5 times of the initial activity. This enhancement was specific for lysosomal fractions among the several rat liver subcellular fractions tested. The activity of purified transglutaminase stimulated by lysosomal fractions was inhibited by pepstatin (50 microgram/ml), chymostatin (50 microgram/ml) and EDTA (1 mM). Preincubation of purified transglutaminase with 5 to 100 microgram/ml cathepsin D caused a time-dependent enhancement of activity up to 9.5-fold over control. This enhancement was specific for cathepsin D among the several lysosomal enzymes tested. These in vitro observations suggest possible activation mechanisms of epidermal transglutaminase in vivo. Epidermal transglutaminase may be activated by lysosomal acid proteinases, such as cathepsin B1 and cathepsin D, which are released and activated during the autolytic stages in granular layer in epidermis.
