Abstract
Hemokinin-1 (HK-1), the newest tachykinin encoded by the Tac4 gene was discovered in 2000. Its name differs from that of the other members of this peptide family due to its first demonstration in B lymphocytes. Since tachykinins are classically found in the nervous system, the significant expression of HK-1 in blood cells is a unique feature of this peptide. Due to its widespread distribution in the whole body, HK-1 is involved in different physiological and pathophysiological functions involving pain inflammation modulation, immune regulation, respiratory and endocrine functions, as well as tumor genesis. Furthermore, despite the great structural and immunological similarities to substance P (SP), the functions of HK-1 are often different or the opposite. They both have the highest affinity to the tachykinin NK1 receptor, but HK-1 is likely to have a distinct binding site and signalling pathways. Moreover, several actions of HK-1 different from SP have been suggested to be mediated via a presently not identified own receptor/target molecule. Therefore, it is very important to explore its effects at different levels and compare its characteristics with SP to get a deeper insight in the different cellular mechanisms. Since HK-1 has recently been in the focus of intensive research, in the present review we summarize the few clinical data and experimental results regarding HK-1 expression and function in different model systems obtained throughout the 16years of its history. Synthesizing these findings help to understand the complexity of HK-1 actions and determine its biomarker values and/or drug development potentials.

Abstract
Our previous studies have shown that an active fragment of human tachykinins (hHK-1(4-11)) produced an opioid-independent analgesia after intracerebroventricular (i.c.v.) injection in mice, which has been markedly enhanced by a δ OR antagonist, naltrindole hydrochloride (NTI). In this study, we have further characterized the in vivo analgesia after i.c.v. injection of hHK-1(4-11) in mouse model. Our qRT-PCR results showed that the mRNA levels of several ligands and receptors (e.g. PPT-A, PPT-C, KOR, PDYN and PENK) have not changed significantly. Furthermore, neither transcription nor expression of NK1 receptor, MOR and POMC have changed noticeably. In contrast, both mRNA and protein levels of DOR have been up-regulated significantly, indicating that the enhanced expression of δ opioid receptor negatively modulates the analgesia induced by i.c.v. injection of hHK-1(4-11). Additionally, the combinatorial data from our previous and present experiments strongly suggest that the discriminable distribution sites in the central nervous system between hHK-1(4-11) and r/mHK-1 may be attributed to their discriminable analgesic effects. Altogether, our findings will not only contribute to the understanding of the complicated mechanisms regarding the nociceptive modulation of hemokinin-1 as well as its active fragments at supraspinal level, but may also lead to novel pharmacological interventions.

Abstract
Endokinins are four novel human tachykinins, including endokinins A (EKA), B (EKB), C (EKC), and D (EKD). Endokinin A/B (EKA/B) is the common C-terminal decapeptide in EKA and EKB, while endokinin C/D (EKC/D) is the common C-terminal duodecapeptide in EKC and EKD. In this study, we attempted to investigate the interactions between EKA/B, EKC/D, and endomorphin-1 (EM-1) on the depressor effect at peripheral level. The effects of EKA/B produced a U-shaped curve. The maximal effect was caused by 10 nmol/kg. EKC/D and EM-1 showed a dose-dependent relationship. Co-administration of EKA/B (0.1, 1, 10 nmol/kg) with EM-1 produced effects similar to those of EKA/B alone but slightly lower. Co-injection of EKA/B (100 nmol/kg) with EM-1 caused an effect stronger than any separate injection. Co-administration of EKC/D (10 nmol/kg) with EM-1 (30 nmol/kg) caused a depressor effect, which was one of the tradeoffs of EM-1 and EKC/D. Mechanism studies showed that SR140333B could block the depressor effects of EKA/B, EKC/D, EM-1, EKA/B+EM-1, and EKC/D+EM-1; SR48968C could block EM-1, EKA/B, EKC/D, and EKC/D+EM-1 and partially block EKA/B+EM-1; SR142801 could block EM-1, EKC/D, and EKC/D+EM-1 and partially block EKA/B and EKA/B+EM-1; naloxone could block EM-1, EKC/D, and EKC/D+EM-1 and partially block EKA/B and EKA/B+EM-1. Pretreatment with NG-nitro-l-arginine methyl ester partially decreased depressor intensity and half-recovery time of EKA/B and EKC/D.

Abstract
Human hemokinin-1 (hHK-1) is a substance P-like tachykinin peptide preferentially expressed in non-neuronal tissues. It is involved in multiple physiological functions such as inflammation, hematopoietic cells development and vasodilatation via the interaction with tachykinin receptor neurokinin-1 (NK1). To further understand the intracellular signal transduction mechanism under such functional multiplicity, current study was focused on the differential activation of Gs and Gq pathways by hHK-1 and its C-terminal fragments, which is termed as functional selectivity. We demonstrated these hHK-1 and related peptide fragments can independently activate Gs and Gq pathways, showing a relative bias toward Gq over Gs pathway. The T1, K3 and Q6 of hHK-1 might play roles in the activation of adenylate cyclase mediated by Gs, while having negligible effect on Gq mediated intracellular calcium release. The stepwise truncation of N-terminal amino acid of hHK-1 caused gradual decrease in ERK1/2 phosphorylation level and NF-κB activity. However, it had little influence on the induction of NK1 receptor desensitization and internalization. Taken together these data support that hHK-1 and its C-terminal fragments are human NK1 receptor agonists with different functional selectivity properties and that such functional selectivity leads to differential activation of downstream signaling and receptor trafficking.

Abstract
Background Human hemokinin-1 (hHK-1) and endokinins are peptides of the tachykinin family encoded by the TAC4 gene. TAC4 and hHK-1 expression as well as effects of hHK-1 in the lung and airways remain however unknown and were explored in this study. Methods RT-PCR analysis was performed on human bronchi to assess expression of tachykinin and tachykinin receptors genes. Enzyme immunoassay was used to quantify hHK-1, and effects of hHK-1 and endokinins on contraction of human and guinea pig airways were then evaluated, as well as the role of hHK-1 on cytokines production by human lung parenchyma or bronchi explants and by lung macrophages. Results In human bronchi, expression of the genes that encode for hHK-1, tachykinin NK1-and NK2-receptors was demonstrated. hHK-1 protein was found in supernatants from explants of human bronchi, lung parenchyma and lung macrophages. Exogenous hHK-1 caused a contractile response in human bronchi mainly through the activation of NK2-receptors, which blockade unmasked a NK1-receptor involvement, subject to a rapid desensitization. In the guinea pig trachea, hHK-1 caused a concentration-dependant contraction mainly mediated through the activation of NK1-receptors. Endokinin A/B exerted similar effects to hHK-1 on both human bronchi and guinea pig trachea, whereas endokinins C and D were inactive. hHK-1 had no impact on the production of cytokines by explants of human bronchi or lung parenchyma, or by human lung macrophages. Conclusions We demonstrate endogenous expression of TAC4 in human bronchi, the encoded peptide hHK-1 being expressed and involved in contraction of human and guinea pig airways.

Abstract
Rat/mouse hemokinin-1 (r/m HK-1), human hemokinin-1 (h HK-1) and human hemokinin-1(4-11) (h HK-1(4-11)) are members of the tachykinin family. In the present study, the coronary vascular activities and cardiac functions of r/m HK-1, h HK-1 and h HK-1(4-11) were investigated in isolated, spontaneously beating guinea pig hearts. Bolus injections of r/m HK-1 caused decrease in perfusion pressure indicative of coronary vasodilation, which was primarily due to the action on tachykinin NK1 receptors on vascular endothelial cells, causing the release of nitric oxide that relaxed the coronary vessels. H HK-1 caused biphasic perfusion pressure changes that were coronary vasodilation followed by coronary vasoconstriction. The mechanisms involved in the vasodilation induced by h HK-1 were similar to that of r/m HK-1 while the mechanisms for coronary vasoconstriction were mediated through the activation of tachykinin NK2 receptors on coronary sympathetic neurons to release catecholamines. H HK-1(4-11) only produced coronary vasoconstriction and the mechanisms involved in this effect were similar to that of h HK-1 in vasoconstriction. Moreover, r/m HK-1 and h HK-1 produced similar decreases in heart rate indicative of negative chronotropic responses and the decreases were mainly mediated through the activation of tachykinin NK1 receptors to release ACh acting on muscarinic receptors. H HK-1(4-11) also produced negative chronotropic response, which was mainly mediated through tachykinin NK2 receptors and muscarinic receptors. Our present results provide evidence that all of the three tachykinins could influence cardiac function and coronary vascular activity in the isolated guinea pig heart.

Abstract
Human hemokinin-1 (h HK-1) and its truncated form h HK-1(4-11) are mammalian tachykinin peptides encoded by the TAC4 gene identified in human, and the biological functions of these peptides have not been well investigated. The tachykinins have shown immuno-regulatory activities in humans. In the present study, we investigated the effects of h HK-1 and h HK-1(4-11) on the proliferation and differentiation of a human promyelocyte leukemia cell line, HL-60. It is noteworthy that h HK-1 (1-300muM) displayed inhibitory effects on the proliferation of HL-60 cells in a dose- and time-dependent manner. The effect of suppressing proliferation induced by these peptides was accompanied by an accumulation of cell cycle in the S phase. Moreover, this peptide induced differentiation of HL-60 cells by significantly increasing the NBT-reduction activity. The effects induced by h HK-1(4-11) on HL-60 cells were similar to that of h HK-1, indicating that it is the active fragment of h HK-1. However these effects induced by h HK-1 or h HK-1(4-11) were not antagonized by the NK(1) receptor antagonist SR140333 or the NK(2) receptor antagonist SR48968. All the results indicated that h HK-1 and h HK-1(4-11) were able to significantly inhibit proliferation and induce differentiation and S phase arrest of a human promyelocyte leukemia cell line HL-60, which may not be mediated through the activation of classical tachykinin NK(1) receptors and tachykinin NK(2) receptors. Our observations also implied that h HK-1 and h HK-1(4-11) could act as immunomodulatory factors in cancer chemotherapy.
