Elevated serum midkine levels in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected patients.

Background: The coronavirus disease-2019 (COVID-19) pandemic has caused important health, economic, social, and cultural problems worldwide. Recent findings demonstrate an excessive cytokine release during the disease development, especially in the seriously life-threatening form of COVID-19. Among other chemokines and cytokines that are released in high amounts at the infection site of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), midkine (MK), which is a potent pro-inflammatory growth factor/ cytokine, can be also overexpressed and contribute to the pathophysiological process in patients infected with SARS-CoV-2.

Association between the Trp64Arg polymorphism of the ADRB3 gene and overactive bladder.

Background: The β -adrenergic receptor (ADRB3) is very important in the regulation of the human detrusor muscle function. The well-known tryptophan64arginine polymorphism of the ADRB3 gene alters the response of the receptor to various stimuli, including adrenalin and noradrenalin, and may increase the susceptibility to develop overactive bladder (OAB). Therefore, this study was performed to determine whether ADRB3 Trp64Arg polymorphism is associated with the pathophysiology of OAB syndrome.

Inhibition of midkine by metformin can contribute to its anticancer effects in malignancies: A proposal mechanism of action of metformin in context of endometrial cancer prevention and therapy.

Metformin, a drug widely used in the treatment of type II diabetes mellitus (T2DM), has been the focus of interest as a potential therapeutic agent for certain types of malignancies, including gynaecological cancers [i.e. endometrial cancer (EC)].

Dual inhibition of P-glycoprotein and midkine may increase therapeutic effects of anticancer drugs.

Multidrug resistance (MDR) to chemotherapy may significantly affect the outcome of cancer treatment. ATP-dependent drug efflux pumps, including P-glycoprotein (P-gp), contribute to the resistance of various chemotherapeutic agents. Overexpression of P-gp in tumor cells induces chemoresistance via pumping the anticancer drugs out of the cells.

Association of the ABCB1 3435C>T polymorphism with antiemetic efficacy of 5-hydroxytryptamine type 3 antagonists.

Background: Resistance to antiemetic treatment with 5-hydroxytryptamine type 3 (5-HT(3)) receptor antagonists is still a major problem resulting in patient discomfort and poor compliance to chemotherapy. We hypothesized that clinical resistance to 5-HT(3) antagonists is associated with the single-nucleotide polymorphism (3435C>T) in the gene that codes for the drug efflux transporter adenosine triphosphate-binding cassette subfamily B member 1 (ABCB1).

Methods: Patients with cancer (N = 216) treated with chemotherapeutic regimens composed of highly or moderately emetogenic agents were examined for their antiemetic responses to tropisetron, ondansetron, or granisetron.

Angiotensin-converting enzyme insertion-deletion polymorphism in primary open-angle glaucoma.

Purpose: To investigate the hypothesis that primary open-angle glaucoma (POAG) is associated with a common insertion-deletion (I/D) polymorphism in the angiotensin-converting enzyme (ACE) gene.

Methods: ACE I/D polymorphism was investigated in a control group of healthy subjects (n = 101) and in a group of patients diagnosed with POAG (n = 104). Polymerase chain reaction detection of I/D polymorphism was used to determine the presence of the two ACE alleles in the groups.

Association between angiotensin converting enzyme gene polymorphism and coronary artery disease in individuals of the South-Eastern Anatolian population.

Methods: Angiotensin converting enzyme genotypes were determined in 133 CAD patients who underwent coronary angiography.

Protective role of glutathione S-transferase P1 (GSTP1) Val105Val genotype in patients with bronchial asthma.

Background: Glutathione S-transferase P1 (GSTP1), the abundant isoform of glutathione S-transferases (GSTs) in lung epithelium, plays an important role in cellular protection against oxidative stress and toxic foreign chemicals. It has been suggested that polymorphisms in the GSTP1 gene are associated with asthma and related phenotypes. As significant interindividual and interethnic differences exist in the distribution of xenobiotic-metabolizing enzymes, we have studied the GSTP1 Ile105Val polymorphism in patients with asthma in a Turkish sample.

Beta 2-adrenergic receptor polymorphism and susceptibility to primary congenital and primary open angle glaucoma.

Objective: It has been shown that arginine to glycine (Arg16Gly), glutamine to glutamic acid (Gln27Glu) and threonine to isoleucine (Thr164Ile) exchanges in codons 16, 27 and 164, respectively, of the beta 2-adrenergic receptor (B2AR) gene significantly alter receptor function. As B2ARs are located on the afferent blood vessels supplying the ciliary body and trabecular meshwork cells, which control aqueous humour dynamics, polymorphisms of B2AR may be involved in the pathophysiology of certain eye diseases, such as glaucoma. Therefore, the aim of the present study was to investigate the distribution of B2AR polymorphisms in patients with primary congenital and primary open angle glaucoma.

T102C polymorphisms at the 5-HT2A receptor gene in Turkish schizophrenia patients: a possible association with prognosis.
