Piperine and piperidine are the two major alkaloids extracted from black pepper (Piper nigrum); piperidine is a heterocyclic moiety that has the molecular formula (CH2)5NH. Over the years, many therapeutic properties including anticancer potential of these two compounds have been observed. Piperine has therapeutic potential against cancers such as breast cancer, ovarian cancer, gastric cancer, gliomal cancer, lung cancer, oral squamous, chronic pancreatitis, prostate cancer, rectal cancer, cervical cancer, and leukemia. Whereas, piperidine acts as a potential clinical agent against cancers, such as breast cancer, prostate cancer, colon cancer, lung cancer, and ovarian cancer, when treated alone or in combination with some novel drugs. Several crucial signalling pathways essential for the establishment of cancers such as STAT-3, NF-κB, PI3k/Aκt, JNK/p38-MAPK, TGF-ß/SMAD, Smac/DIABLO, p-IκB etc., are regulated by these two phytochemicals. Both of these phytochemicals lead to inhibition of cell migration and help in cell cycle arrest to inhibit survivability of cancer cells. The current review highlights the pharmaceutical relevance of both piperine and piperidine against different types of cancers.

Abstract C/EBPδ belongs to the family of highly conserved CCAAT/enhancer binding protein (C/EBP) transcription factors. Members of this family play a critical role in the regulation of mitotic growth arrest and differentiation in numerous cell types. To examine the consequences of C/EPBδ expression, we transfected C/EPBδ into CML myeloid leukemia (KCL22, K562), prostate (LNCaP, PC3, DU145), and breast (MCF-7, T47D, MDA-MB-231) cancer cell lines. C/EBPδ expression resulted in a proliferative arrest and an increase in apoptosis of the myeloid leukemia cells, as well as the prostate cells LNCaP and PC3, and the breast cells MCF-7 and T47D. In contrast, DU145 prostate and MDA-MB-231 breast cancer cells were not inhibited by C/EBPδ, indicating that the biologically properties of C/EBPδ depend upon its cellular context. We further studied the molecular mechanisms underlying the affect of C/EPBδ expression in CML leukemic cells. Myeloid differentiation of KCL22 and K562 blast cells as shown by morphologic changes and induction of secondary specific granule genes, occurred within 4 days of inducing expression of C/EBPδ. Furthermore, expression of C/EBPδ was associated with downregulation of c-Myc and cyclin E, and upregulation of the forkhead transcription factor FoxO1a (FKHR) and the cyclin-dependent kinase inhibitor p27Kip1. In addition, microarray analysis showed that C/EBPδ mRNA is upregulated during granulocytic differentiation of normal CD34+ bone marrow cells, suggesting that C/EBPδ is involved in lineage-specific differentiation. Taken together, these results show that expression of C/EBPδ in BCR-ABL-positive CML cells in blast crisis, is sufficient for neutrophil differentiation and suggest that ectopic induction of C/EBPδ in the blastic phase of CML, as well as in certain cases of prostate and breast cancers, may hold promising therapeutic potential.

Background and Objective: Herbal extracts and plant compounds are increasingly becoming of interest for their therapeutic potential in various cancer types. Momordica charantia is well known for its anti-diabetic, anti-inflammatory, and anti-cancer properties. Methods: In the present study, we investigated the antiproliferative and pro-apoptotic effects of Momordica charantia seed and aryl extracts on breast cancer cells and explored the underlying molecular mechanisms. Results: Our results showed that both extract significantly inhibited the growth of MCF-7 and MDA MB-231 cells in a concentration-dependent manner, and induced apoptosis by upregulation of caspase 9 and caspase 3 mRNA levels. In addition, in different incubation time, both extract evidently inhibited EGF and induced EGFR phosphorylation/activation in both cell lines. Moreover, Momordica charantia aryl and seed extracts inhibited phosphorylation/activation of PI3K/AKT and MAPK (ERK and P38) pathways in both cell lines. Conclusion: The current study clearly demonstrates that the Momordica charantia aryl and seed extracts have the potential to exert its cytotoxic effect on breast cancer cells by a mechanism involving inhibition of EGFR and EGRF related pathways with the induction of apoptosis. The overall finding demonstrates that this plant, especially seed extract, could be a potential source of new anticancer compounds for possible drug development against cancer.

As we enter into the era of modern medicine, breast cancer remains a significant public health concern that has a noteworthy global impact in developed and developing countries. The modern era has seen an increase in the knowledge of the molecular mechanisms underlying cancer progression, leading to many anticancer drugs. The practice of curing certain diseases with the help of plant-derived compounds was one of the traditional methods. Phytochemicals and derivatives present in plants have shown a promising effect for improving efficiency in the treatment of cancer patients and reducing adverse reactions such as integration therapy with chemotherapeutic agents. The primary objective of this review is to compile ongoing research, preclinical studies, and clinical trials of some of the important phytochemicals. In recent years, increasing evidence from preclinical and clinical studies suggests that phytochemicals can favorably modulate several signaling pathways involved in cancer development and progression. Furthermore, phytoconstituents or plant-derived compounds show synergistic action against breast cancer when integrated with chemotherapy. Thus, the therapeutic potential of naturally occurring phytochemicals is of great interest as a part of integration therapy in cancer care. This review focuses on phytochemicals from quinones, terpenoids, alkaloids, polyphenols, steroidal lactones, and glycosides classes that help treat breast cancer. In addition, the phytochemicals act by various pharmacological mechanisms like carcinogen inactivation, inhibiting proliferation, cell cycle arrest, and apoptosis. Collectively, detailed information about specific classes of phytoconstituents along with their mechanism of action is mentioned in this review.

Hox Protein

: HOX genes belong to the highly conserved homeobox superfamily, responsible for the regulation of various cellular processes that control cell homeostasis, from embryogenesis to carcinogenesis. The abnormal expression of HOX genes is observed in various cancers, including breast cancer; they act as oncogenes or as suppressors of cancer, according to context. In this review, we analyze HOX gene expression patterns in breast cancer and examine their relationship, based on the three-dimensional genome structure of the HOX locus. The presence of non-coding RNAs, embedded within the HOX cluster, and the role of these molecules in breast cancer have been reviewed. We further evaluate the characteristic activity of HOX protein in breast cancer and its therapeutic potential.
