Abstract
Cancer along with cardiovascular disease are the main causes of death in the industrialised countries around the World. Conventional cancer treatments are losing their therapeutic uses due to drug resistance, lack of tumour selectivity and solubility and as such there is a need to develop new therapeutic agents. Therapeutic peptides are a promising and a novel approach to treat many diseases including cancer. They have several advantages over proteins or antibodies: as they are (a) easy to synthesise, (b) have a high target specificity and selectivity and (c) have low toxicity. Therapeutic peptides do have some significant drawbacks related to their stability and short half-life. In this review, strategies used to overcome peptide limitations and to enhance their therapeutic effect will be compared. The use of short cell permeable peptides that interfere and inhibit protein-protein interactions will also be evaluated.

Abbasian M, Eslampanah Seyedi HA, Sayed Tabatabaei BE, Arab-Bafrani Z, Mofid MR, Zareie R. Recombinant production, purification and characterization of vessel dilator in E. coli. Protein Expr Purif 2016; 129:75-83. [PMID: 27664437 DOI: 10.1016/j.pep.2016.09.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2016] [Revised: 09/10/2016] [Accepted: 09/20/2016] [Indexed: 10/21/2022]
Abstract
Vessel dilator is a 3.9-KDa potent anticancer peptide and a valuable candidate in the treatment of conditions such as congestive heart failure and acute renal failure amongst others. Here we report the recombinant production of vessel dilator in Escherichia coli. Three different synthetic ORF's dubbed VDI, VDII and VDIII, each encoding a trimmer of the vessel dilator peptide attached to a His tag sequence at their C- terminal, were synthesized and placed in pET21c expression vectors. The highest yield, following expression in E. coli BL21 (DE3), was recorded with VDII that carried the shortest fusion partner. Subsequent to the initial capture of the fusion protein by a Ni affinity column, the vessel dilator monomers were cleaved by trypsin treatment, and further purified to at least 90% homogeneity by anion exchange chromatography. De-novo sequencing and in vivo anticancer activity tests were used to verify the peptide sequence and its biological activity, respectively. The final yield was estimated to be approximately 15 mg of the purified vessel dilator per gram wet weight of the bacterial cells.

Subramanian V, Vellaichamy E. Atrial natriuretic peptide (ANP) inhibits DMBA/croton oil induced skin tumor growth by modulating NF-κB, MMPs, and infiltrating mast cells in swiss albino mice. Eur J Pharmacol 2014; 740:388-97. [PMID: 25058907 DOI: 10.1016/j.ejphar.2014.07.024] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2014] [Revised: 07/11/2014] [Accepted: 07/14/2014] [Indexed: 01/29/2023]
Abstract
Cardiac hormone atrial natriuretic peptide (ANP) and its receptor, natriuretic peptide receptor-A (NPR-A) are implicated as a vital regulator of cancer cell growth and tumor progression. However, the underlying mechanism by which ANP opposes the cancer growth in in-vivo remains unknown. Herein, we investigated the anti-cancer activity of ANP on 7, 12-dimethyl benzanthracence (DMBA)/Croton oil- induced two-step skin carcinogenic mouse model. Skin tumor incidence and tumor volume were recorded during the experimental period of 16 weeks. ANP (1 μg/kg body weight/alternate days for 4 weeks) was injected subcutaneously from the 13th week of DMBA/Croton oil induction. ANP treatment markedly inhibited the skin tumor growth (P<0.001). A significant reduction in the level of NF-κB activation (P<0.001), infiltrating mast cell count (P<0.01) and MMP-2/-9 (P<0.001, respectively) were noticed in the ANP treated mice skin tissue. Further, ANP treatment revert back the altered levels of serum LDH-4, C-reactive protein (CRP), and enzymatic antioxidants (SOD and CAT activities) to near normal level. Taken together, the results of this study suggest that ANP opposes the skin carcinogenesis by suppressing the inflammatory response and MMPs.

Ding JH, Chang YS. Atrial natriuretic peptide: a possible mediator involved in dexamethasone's inhibition of cell proliferation in multiple myeloma. Med Hypotheses 2012; 79:207-9. [PMID: 22595807 DOI: 10.1016/j.mehy.2012.04.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2011] [Revised: 04/17/2012] [Accepted: 04/22/2012] [Indexed: 11/26/2022]
Abstract
Atrial natriuretic peptide (ANP) has been recognized for several decades for its role of regulating blood pressure. Recently, cumulating evidences show that ANP plays an anticancer role in various solid tumors via blocking the kinase cascade of Ras-MEK1/2-ERK1/2 with the result of inhibition of DNA synthesis. ANP, as well as its receptors (NPR-A and NPR-C) has been identified present in the embryonic stem cell and a wide range of cancer cells. Various lymphoid organs, such as lymph nodes, have been detected the presence of ANP. Multiple myeloma (MM), though the therapies have evolved significantly, is still an incurable disease as B lymphocyte cell neoplasm. Dexamethasone is the cornerstone in treatment of MM via inactivation of Ras-MEK1/2-ERK1/2 cascade reaction. Coincidently, dexamethasone can increase the expression of ANP markedly. Nevertheless, the role of ANP in MM is unclear. Based on these results above, we raise the hypothesis that ANP is involved in mediating dexamethasone's inhibition of proliferation in MM cells, which suggests that ANP may be a potential agent to treat MM.

Vesely DL. Cardiac Hormones Target the Ras-MEK 1/2-ERK 1/2 Kinase Cancer Signaling Pathways. Cancers (Basel) 2011; 3:1182-94. [PMID: 24212659 PMCID: PMC3756409 DOI: 10.3390/cancers3011182] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2011] [Revised: 03/02/2011] [Accepted: 03/03/2011] [Indexed: 12/04/2022] Open
Abstract
The heart is a sophisticated endocrine gland synthesizing the atrial natriuretic peptide prohormone which contains four peptide hormones, i.e., atrial natriuretic peptide, vessel dilator, kaliuretic peptide and long-acting natriuretic peptide, which decrease up to 97% of human pancreatic, breast, colon, prostate, kidney and ovarian carcinomas as well as small-cell and squamous cell lung cancer cells in cell culture. In vivo, these four cardiac hormones eliminate up to 80% of human pancreatic adenocarcinomas, two-thirds of human breast cancers, and up to 86% of human small-cell lung cancers growing in athymic mice. Their signaling in cancer cells includes inhibition of up to 95% of the basal activity of Ras, 98% inhibition of the phosphorylation of the MEK 1/2 kinases and 97% inhibition of the activation of basal activity of the ERK 1/2 kinases mediated via the intracellular messenger cyclic GMP. They also completely block the activity of mitogens such as epidermal growth factor's ability to stimulate ERK and Ras. They do not inhibit the activity of ERK in healthy cells such as human fibroblasts. The final step in their anticancer mechanism of action is that they enter the nucleus as demonstrated by immunocytochemical studies to inhibit DNA synthesis within cancer cells.
