RESUMEN

Bioactive fractions obtained from medicinal plants which have been used for the treatment of multiple diseases could exert their effects by targeting common pathways. Prior knowledge of their usage could allow us to identify novel molecular links. In this study, we explored the molecular basis of action of one such herbal formulation Cissampelos pareira L. (Cipa), used for the treatment of female hormone disorders and fever. Transcriptomic studies on MCF7 cell lines treated with Cipa extract carried out using Affymetrix arrays revealed a downregulation of signatures of estrogen response potentially modulated through estrogen receptor α (ERα). Molecular docking analysis identified 38 Cipa constituents that potentially bind (ΔG < - 7.5) with ERα at the same site as estrogen. The expression signatures in the connectivity map ( https://clue.io/; ) revealed high positive scores with translation inhibitors such as emetine (score: 99.61) and knockdown signatures of genes linked to the antiviral response such as ribosomal protein RPL7 (score: 99.92), which is a reported ERα coactivator. Further, gene knockdown experiments revealed that Cipa exhibits antiviral activity in dengue infected MCF7 cells potentially modulated through estrogen receptor 1. This approach reveals a novel pathway involving the ESR1-RPL7 axis which could be a potential target in dengue viral infection.

RESUMEN

Human Papillomavirus type 16 (HPV-16) has a significant role in various cancers and Alzheimer's disease. 500 breast cancer mammograms as well as 3 cases of adenocarcinomas of esophagus, stomach, colon, prostate gland, uterus, ovary that was examined had significant infection of HPV- 16 with significantly increased ß- amyloid (1-42). When a strong HPV-16 infection is found in the oral cavity, repeated exposure to the infected individual's coughing can infect others easily through saliva. Just like all of above cancer tissues, all 20 Alzheimer's cases that were examined had significantly increased HPV-16 of 1500-3000ng with markedly reduced Acetylcholine of 0.5~1.5ng and significantly increased 3- amyloid (1-42) of 7.5ng or higher. Since every cancer and Alzheimer's patient examined had significantly reduced amounts of Vitamin D3 and Taurine, the author examined the effects of Vitamin D3 and Taurine independently, or by combination. Each of optimal doses of Vitamin D3 and Taurine had significant beneficial effects that were anti-cancer, anti-cardiac ischemia, and memory loss & other brain problems, with significant excretion of HPV- 16 and bacteria such as Borrelia Burgdorferi, if it exists, through the urine, without using any anti-viral or anti-bacterial agents. However, when optimal doses of Taurine and Vitamin D3 were used together, 3 times/day, there was reduction of cancer-associated Oncogene CfosAB-2 or Integrin a5p1 with significantly high values of 200-500ng which were reduced to 0.001-0.004ng. Memory and brain function improved by increasing markedly reduced abnormal Acetylcholine of 1.5ng or less to a few hundred-2500ng with increase in DHEA. Abnormally increased P-amyloid (1-42) is markedly reduced. Ischemic heart, where there is abnormally increased Cardiac Troponin I, reduced significantly. In addition, abnormally reduced DHEA levels often increase. HPV- 16 in urine increased from an average of 100~15ng to an average of 4000ng and cancer related parameters in the urine significantly increased. Thus, the author found combined use of optimal dose of Vitamin D3 400 I.U. and optimal dose of Taurine 175mg, 3/day, was found to be one of the safest, most effective treatments for cancer, memory problems & other brain abnormality, and Ischemic heart problems, and this combination seems to improve any part of the body. One should try this method before using any other treatment, which has a potential side effect.

RESUMEN

Attachment theory provides a framework for understanding individual differences in chronic interpersonal stress. Attachment anxiety, a type of relationship insecurity characterized by worry about rejection and abandonment, is a chronic interpersonal stressor. Stress impacts cellular immunity, including herpesvirus reactivation. We investigated whether attachment anxiety was related to the expression of a latent herpesvirus, Epstein-Barr virus (EBV), when individuals were being tested for breast or colon cancer and approximately 1 year later. Participants (N=183) completed a standard attachment questionnaire and provided blood to assess EBV viral capsid antigen (VCA) IgG antibody titers. Individuals with more attachment anxiety had higher EBV VCA IgG antibody titers than those with less attachment anxiety. The strength of the association between attachment anxiety and antibody titers was the same at both assessments. This study is the first to show an association between latent herpesvirus reactivation and attachment anxiety. Because elevated herpesvirus antibody titers reflect poorer cellular immune system control over the latent virus, these data suggest that high attachment anxiety is associated with cellular immune dysregulation.

RESUMEN

In the past, Human Papillomavirus Type 16 (HPV-16) was considered to be the main cause of cancer in the oropharynx and genital organs. Cervical cancer of the uterus is the most well-known cancer associated with HPV-16. Among the oncogenic HPVs, types 16 and 18 are most responsible for the majority of the HPV-caused cancers. Recently, using EMF Resonance Phenomenon between 2 identical substances, we non-invasively measured HPV-16 and HPV-18 among 25 physicians and 25 dentists and found that all 50 have HPV-16 in oral cavities and oropharynx but not HPV-18. However most dentists have a stronger infection than physicians. Among them were 2 female dentists with breast cancer containing HPV-16 and strong infections of HPV-16 in the oral cavities and oropharynx. When the author checked their breast cancer positive areas as well as the mammograms of cancer positive areas, Chrysotile Asbestos co-existed with an infection of HPV-16. We then examined over 500 published mammograms of women with malignant breast cancer published by other institutes, and we found HPV-16 in more than 97% and HPV-18 in less than 3% of the breast cancer mammograms examined. Less than 0.4% of cases were found as a variety of combination of HPV-16 & HPV-18. We also discovered that breast cancer with HPV-16 always co-exists with increased Chrysotile Asbestos deposits, and the outline of the breast cancer positive area is a relatively smooth and round or oval shape, and breast cancer with HPV-18 always co-exists with increased Tremolite Asbestos, where the tumor outline is an irregular saw-tooth like zigzag pattern. Based on these findings, better methods of diagnosis, treatment and prevention with a vaccine can be developed.

RESUMEN

Immunosuppressive therapy, such as chemotherapy or the use of corticosteroids, may stimulate reactivation of hepatitis B virus (HBV). Most of these episodes occur in patients whose hepatitis B surface antigens are positive (HBsAg+). We report a case of HBV reactivation in a patient with negative HBsAg during chemotherapy for breast cancer, in spite of avoiding corticosteroids. A 68-year-old woman received adjuvant chemotherapy for breast cancer. Her serological examinations showed that HBsAg, HBeAg, and HBV-DNA were all negative. Her chemotherapy consisted of CAF (cyclophosphamide 500 mg/m(2), doxorubicin 50 mg/m(2), fluorouracil 500 mg/m(2)) without administration of corticosteroids. She received six cycles of CAF. At day 27 after her sixth CAF, she was admitted to the hospital with acute hepatitis B virus (HBV) reactivation. She received glycyrrhizinic acid by intravenous injection (80 mg/day), ursodeoxycholic acid (300 mg/day), and entecavir (0.5 mg/day). Then she received interferon by intravenous injection (3 million units/day), prednisolon by intravenous injection (45 mg/day), and plasma exchange therapy. However, she died of liver failure. This is a rare case in which HBV reactivation occurred in an HBsAg negative patient during chemotherapy without using corticosteroids. This episode suggests that HBV reactivation may occur during chemotherapy in any patient with a history of HBV infection. Therefore, we recommend checking HBsAg, HBsAb, and HBcAb before starting chemotherapy. Moreover, with positive HBsAb or/and HBcAb patients, HBV-DNA should be checked before starting chemotherapy and monitored during chemotherapy by a sensitive PCR method.

RESUMEN

BACKGROUND: Patients receiving chemotherapy are at increased risk for influenza virus infection. Little is known about the preferred moment of vaccination during chemotherapy. PATIENTS AND METHODS: Breast cancer patients received influenza vaccination during FEC (5-fluorouracil, epirubicin and cyclophosphamide)-containing chemotherapy regimens. Patients were randomised for early (day 4) or late (day 16) vaccination during the chemotherapy cycle. Influenza virus-specific antibody titres were determined before and 3 weeks after vaccination by haemagglutination inhibition. RESULTS: We included 38 breast cancer patients (20 in the early and 18 in the late group) and 21 healthy controls. The overall patient group had significant lower responses to the vaccine compared with healthy controls. Patients vaccinated at day 4 tended to have higher antibody titres as compared with patients vaccinated at day 16, although the difference in post-vaccination titres is not statistically significant. Geometric mean titres post-vaccination for day 4 versus day 16 were 63.7 versus 29.5 (H3N2), 28.2 versus 19.6 (H1N1) and 29.8 versus 16.0 (B/Brisbane), respectively. CONCLUSIONS: Patients on chemotherapy have significantly lower responses to influenza virus vaccination compared with healthy controls. Vaccination early during the chemotherapy cycle induces better responses than does vaccination at day 16 of the cycle. Follow-up studies are needed to confirm this effect.

RESUMEN

Several independent studies have presented evidence for the involvement of human papillomaviruses (HPV) in the aetiology of human breast cancer, while others have reported the opposite findings. Here, we have analysed by a high sensitive multiplex PCR-based method the prevalence of alpha mucosal and beta cutaneous HPV DNA in 90 ductal lavages, colostrum and milk. Ten of the 70 DLs analyzed (14%) contained a single or multiple beta HPV types, while DNA from mucosal high-risk HPV types was detected in only one sample (1/70). A strong reduction of HPV positivity in DL fluids was observed in 45 specimens collected after removal of the superficial layers of the nipple epidermis. All DLs were negative for the mucosal low-risk HPV types 6 and 11. Finally, HPV positivity was low in colostrum and milk. Our data show that DNA of alpha mucosa and beta cutaneous HPV types are rarely present in the breast fluids and suggest that a direct role of HPV in breast carcinogenesis is unlikely.

RESUMEN

BACKGROUND: There is seemingly consistent and compelling evidence that there is no association between breastfeeding and breast cancer. An assumption follows that milk borne viruses cannot be associated with human breast cancer. We challenge this evidence because past breastfeeding studies did not determine "exposure" of newborn infants to colostrum and breast milk. METHODS: We conducted a prospective review of 100 consecutive births of infants in the same centre to determine the proportion of newborn infants who were "exposed" to colostrum or breast milk, as distinct from being fully breast fed. We also report a review of the breastfeeding practices of mothers of over 87,000 newborn infants in the Australian State of New South Wales. This study was approved by the Human Research Ethics Committee of the University of New South Wales (Sydney, Australia). Approval 05063, 29 September 2005. RESULTS: Virtually all (97 of 100) newborn infants in this centre were "exposed" to colostrum or breast milk whether or not they were fully breast fed. Between 82.2% to 98.7% of 87,000 newborn infants were "exposed" to colostrum or breast milk. CONCLUSION: In some Western communities there is near universal exposure of new born infants to colostrum and breast milk. Accordingly it is possible for the transmission of human milk borne viruses. This is contrary to the widespread assumption that human milk borne viruses cannot be associated with breast cancer.

RESUMEN

BACKGROUND: Hyperbaric oxygenation (HBO) therapy is the administration of 100%-inhaled oxygen to patients at increased atmospheric pressure. MATERIALS AND METHODS: We used an in vitro model to examine the effects of HBO on mammary cell proliferation. Normal mammary epithelia, primary tumor and metastatic tumor cells derived from the same patient and immortalized by transfection with the human papilloma virus E6 oncogene, as well as the MCF7 human mammary adenocarcinoma cell line, were studied. RESULTS: HBO (97.9% O2, 2.1% CO2, 2.4 atmospheres absolute) inhibited the proliferation of all 4 cell types as measured by light microscopy, [3H]thymidine uptake, a tetrazolium-based colorimetric assay and a clonogenicity assay. The anti-proliferative effect of HBO was time-dependent (p < 0.01 for all 4 cell types). Hyperoxia alone (95% O2, 5% CO2, 1 atmosphere absolute) and increased atmospheric pressure alone (8.75% O2, 2.1% CO2, 2.4 atmospheres absolute) also inhibited proliferation, but their effects were not as profound as HBO (p < 0.01 when either hyperoxia or increased pressure was compared to HBO for all 4 cell types). HBO enhanced the anti-proliferative effects of melphalan (p < 0.05), gemcitabine (p < 0.001) and paclitaxel (p < 0.001). The clonogenicity assay demonstrated that the effects of HBO were still evident 2 weeks after the exposure (p < 0.01 for all 4 cell types). Experiments using Hoechst-propidium iodide or annexin V-propidium iodide staining showed no HBO-induced increases in necrosis or apoptosis. CONCLUSION: HBO inhibits benign and malignant mammary epithelial cell proliferation, but does not enhance cell death.
