Objectives : In this study, we investigated the anti-proliferative and apoptosis inducing effect of water extract of Chelidonium majus (CM) on human breast cancer cell MDA-MB-231. Methods : The MTT assay was used to assess cell proliferation. The expression of apoptosis related gene was assessed by quantitative Real-time PCR. Cell apoptosis detected by flow cytometry using Annexin-V/PI staining. Results : Our data revealed that CM inhibited the cell growth in a dose dependent manner (0, 62.5, 125, 250, 500 μg/ml). CM increased mRNA expression of pro-apoptotic genes Bax, caspase-3, and caspase-9. Annexin-V/PI staining assays revealed that apoptosis-induced cell death increased in a dose-dependent manner in cells. Conclusions : CM induces cell death in MDA-MB-231 human breast cancer cell and shows potentials for use in cancer therapy as apoptosis-inducing agent.

Ayurveda scholars have well described about the physio-anatomical aspect of mammary gland (Stana), physiology of lactation, importance of breast milk (Stanya) in growth and development of baby, various factors affecting the lactation and causing changes in property of milk, Galactogouge (Stanyajanana), and drugs for purification of mother milk (Stanya Shodhana). The recent studies provide evidence for above descriptions of Ayurveda. Breast milk (Stanya) is the nearly complete sole source of nourishment for infants. It has been considered as subsidiary tissue (Upadhatu) of blood plasma (Rasa Dhatu) as it is formed out of Rasa Dhatu (Plasma) and its quality and quantity gets affected by quality of nutrient fraction of food formed after complete digestion (Aahar Rasa). It provides health (Aarogya), strength and immunity (Bala) to the feeding child and gives innumerable beneficial effects like protection against not only acute infections like URTI, diarrhoea but also on chronic illnesses like CVD, metabolic disorders too. The Ayurveda description related to Mammary gland and physiology of lactation still need a better understanding for its implementation on promotion of health. Thus an attempt has been made to compile and analyze the view of Ayurveda scholars on Breast (Stana), Breast milk (Stanya) and physiological aspect of lactation as well as to draw a possible scientific understanding for the relevance.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign mesenchymal lesion with incidental histologic findings. Surgical excision is recommended as the treatment of choice for PASH, although the recurrence rates after excision range from 15% to 22%. A 46-year-old-female presented with a six-month history of bilateral breast enlargement and painful sensation mimicking inflammatory carcinoma. Imaging studies demonstrated innumerable enhancing nodules in both breasts. Due to the growth of the lesions and progressive clinical symptoms, bilateral subcutaneous mastectomy was performed. Grossly, the specimens were round and well-circumscribed, and the histologic examination revealed PASH. After mastectomy, we created a pocket with the pectoralis major muscle and a lower skin flap, which was deepithelized. Anatomical mammary implants were inserted, and the nipple areolar complex was transferred to a new position as a free graft. The aesthetic result was satisfactory after twelve months of follow-up.

In our program to search for new AMP-activated protein kinase (AMPK) activators from plants that exert potential anticancer property, we found that an EtOAc extract of Myristica fragrans (nutmeg) activated AMPK enzyme in human breast cancer MCF-7 cells. Two major diarylbutane-type lignans, macelignan and meso-dihydroguaiaretic acid (MDGA), were isolated as active principles from this extract. Treatment of breast cancer cells with two compounds induced cellular apoptosis, evidenced by cleavage of poly-(ADP-ribose) polymerase (PARP) and Ser 15 phosphorylation of p53. Moreover, macelignan and MDGA significantly inhibited the colony formation of MCF-7 breast cancer cells on soft agar. Intraperitoneal injection of macelignan and MDGA (20 mg/kg) suppressed the tumor growth of 4T1 mammary cancer cells. These results indicate that the chemopreventive effects of two major diarylbutane-type lignans from Myristica fragrans (nutmeg) may be associated with induction of apoptosis presumably through AMPK activation.

Butein(3,4,2',4-tetrahydroxychalcone) has been reported anticancer effects in several cancer type, which is prostate, bladder cancer but breast cancer is not. This study was to investigate the antiproliferative effects by butein(3,4,2',4-tetrahydroxychalcone) in MCF-7 human breast carcinoma cells. We invastigated the effects of dose-dependently cell growth inhibition by butein, which could be proved by WST-1 assay. Also, flow cytometry analysis was butein increase percentage of subG1 phase. As well as, butein induces apoptosis through the expression of caspase-8,-3 and poly(ADP-ribose) polymerase(PARP) activation but not in DMSO treated cells. Taken together, this results suggest that butein induced MCF-7 apoptosis through extrinsic pathway and thus may have potential tumor suppressor in breast cancer.

Invasive micropapillary carcinoma (IMPC) of the breast is recently described rare variant of invasive ductal carcinoma. This variant has a distinctive histological features and aggressive biological behavior. We reviewed the cytologic features of eight cases of IMPC. The cytologic smears showed moderate to high cellularity and the tumor tissue was composed of atypical, angulated, cohesive clusters of neoplastic cells with a papillary to tubuloalveolar architecture, and a morular growth pattern without fibrovascular cores was seen on the histopathology. IMPC of the breast has distinctive cytologic features and it is important to make an early diagnosis via fine needle aspiration cytology due to this tumor's aggressive behavior.

Purpose: The purpose of this study was to understand the meaning of prayer in Christian patients with breast cancer. Methods: Data collection and analysis were conducted by the Colaizzi analysis of phenomenological method. Data were collected by in-depth interviewing the participants and by further follow-up observations. Sixteen patients participated in this study. Results: The significant statements (188), formulated meanings (42), themes (38), clusters of theme (10), and categories (5) were emerged. The 5 categories were as follows: communication with God, healing and peace, spiritual growth, distrust in prayer, and method of prayer. Conclusion: Further studies need to consider the period of faith, comparison between christian and other religions, and length of diagnosis. A better understanding of the meaning of prayer will lead to a more comprehensive view of the spiritual care for patients with breast cancer, and can lead to guidelines for assessment and intervention to reduce suffering from cancer.

A case of invasive cribriform carcinoma of the breast is presented with fine needle aspiration cytologic features. The aspiration was performed from a papable 2.0 cm mass in the upper outer quadrant of the right breast in a 53 year-old woman. The aspirate showed cellular smear composed of larger three dimensional tight clusters, smaller monolayered loose clusters, and many individual cells on the clean background. In the clusters, the tumor cells were bordering central lumina, quite similar to the cribriform in histology. The tumor cells in the clusters and individual tumor cells had uniform, small and round nuclei. The chromatin was finely granular, and nuclear membrane was smooth No discernible nucleoli were present (nuclear grade $1\sim2$). Unless the abundance of individual cells and the cribriform growth pattern are recognized in the smear, the cytologic diagnosis of invasive cribriform carcinoma is difficult.

The aim of present study was to investigate the effects of kaempferol on cellular proliferation and cell cycle arrest and explore the mechanism for these effects in human breast carcinoma MDA-MB-453 cells. Cells were treated with kaempferol at various concentrations (ranging from 1 to $200\;{\mu}M$) for 24 and 48 hrs. Kaempferol significantly inhibited cancer cell growth in cells exposed to 50 and $10\;{\mu}M$ of kaempferol and incubated for 24 and 48 hrs, respectively. Exposure to kaempferol resulted in cell cycle arrest at the G2/M phase. Of the G2/M-phase related proteins, kaempferol down-regulated CDK1 and cyclin A and B in cells exposed to kaempferol. In addition, small DNA fragments at the sub-G0 phase were increased by up to 23.12 and 31.90% at 10 and $50\;{\mu}M$ incubated for 24 and 48 hrs, respectively. The kaempferol-induced apoptosis was associated with the up-regulation of p53. In addition, the phosphorylation of p53 at the Ser-15 residue was observed with kaempferol. Kaempferol inhibits cell proliferation by disrupting the cell cycle, which is strongly associated with the induction of arrest at G2/M phase and may induce apoptosis via p53 phosphorylation in human breast carcinoma MDA-MB-453 cells.

c-Jun N-terminal kinases (JNKs) have a Janus face, regulating both cell apoptosis and survival. The present study focused on understanding the function of JNK in tumor development and the chemoresistance underlying JNK-mediated cancer cell survival. We identified an inhibitor of JNK1, an important regulator of cancer cell survival. Kinase assay data showed that JNK1-dependent c-Jun phosphorylation was inhibited by indirubin derivatives. In particular, indirubin-3-monoxime (I3M) directly inhibited the phosphorylation of c-Jun in vitro, with a half inhibition dose (IC₅₀) of 10 nM. I3M had a significant inhibitory effect on JNK1 activity. Furthermore, we carried out assays to determine the viability, migration, and proliferation of breast cancer cells. Our results demonstrated that cell growth, scratched wound healing, and colony forming abilities were inhibited by the JNK inhibitor SP600125 and I3M. The combination of SP600125 and I3M significantly decreased cancer cell proliferation, compared with either SP600125 or I3M alone. Our studies may provide further support for JNK1-targeting cancer therapy using the indirubin derivative I3M in breast cancer.
