Turkish Journal of Biology
Unnecessary weed growth in sugarcane fields forces plants to compete for nutrients and sunlight for survival, which most often leads to significant yield losses. As chemical herbicides cannot differentiate between crop plants and weeds, the development of herbicide-tolerant crops is anticipated. Four sugarcane varieties, CPF-234, CPF-213, HSF-240, and CPF-246, were used to develop glyphosate herbicide tolerance. A glyphosate-tolerant gene of 1368 bp cloned directionally under the 35S promoter with the \Beta-glucuronidase (GUS) reporter gene was used as the transgene. Through the biolistic transformation of sugarcane, calli of all cultivars were transformed with glyphosate-tolerant gene constructs. Efficient regeneration conditions were optimized …

Glycosylation Changes Leading To The Increase In Size On The Common Core Of N-Glycans, Required Enzymes, And Related Cancer-Associated Proteins, Sabi̇re Karaçali, Savaş İzzetoğlu, Remzi̇ye Deveci̇
Turkish Journal of Biology
Glycan parts of glycoconjugates on the surfaces of cells regulate many kinds of interactions between the cells and their immediate environments. Alterations in glycosylation on the cancer-associated glycoproteins are responsible for changes in their molecular interactions and biological functions. Glycosylation changes occur in the core and/or at the nonreducing end of the oligosaccharide chains of N-glycans. In this review, we focus on the branching of the common core structure of N-glycans, the responsible enzyme, and the extensions of some of the branches causing size increases on the surface of tumor cells. Abnormal branching, elongation of the branches, and increasing size …

Progesterone Receptor Modulators In Breast Cancer, Ronald D. Wiehle
Turkish Journal of Biology
Breast cancer has been treated successfully with selective estrogen receptor antagonists (SERMs) such as tamoxifen, receptor-depleting agents such as fulvestrant, and aromatase inhibitors such as anastrozole. Selective progesterone receptor modulators (SPRMs or PRMs) have not been studied as much and are currently under investigation for inhibition of mammary carcinogenesis in animal models and breast cancer prevention trials in women. They might follow tamoxifen and aromatase inhibitors in the adjuvant treatment of breast cancers with acquired resistance. These uses have not provoked ground-breaking progress or studies and PRMs do not have a high profile. Most in vitro and in vivo studies …
The Role Of Abc Transporters In Anticancer Drug Transport, Serhan Karvar
The Role Of Abc Transporters In Anticancer Drug Transport, Serhan Karvar
Turkish Journal of Biology
The main clinical problem in cancer treatment is the development of multidrug resistance. Tumors can be intrinsically drug-resistant or develop resistance to chemotherapy. Multidrug resistance can develop by diverse mechanisms including decreased rate of drug uptake, increased drug efflux, alterations in drug metabolism, mutation of drug targets, activation of DNA repair mechanisms, and evasion of apoptosis. The use of modern genomic, proteomic, bioinformatic, and systems biology approaches has resulted in a substantial increase in our ability to identify molecular mechanisms that are involved in multidrug resistance in cancer and to find drugs that may block or reverse the development of …

Noncoding Rnas And Cancer, Hesna Begüm Akman Tuncer, Ayşe Eli̇f Erson Bensan
Turkish Journal of Biology
New and diverse groups of noncoding RNAs are beginning to be discovered. These noncoding RNAs are grouped based on their sizes, genomic positions, or distinctive functions ranging from the regulation of chromatin structure and gene expression to genome stability maintenance. Among noncoding RNAs, microRNAs are the best studied and understood small RNAs with direct and indirect roles in normal and in cancer cells. Given the high rate of transcription from noncoding parts of the genome, other noncoding elements are also of great interest. It is also of interest to understand that there may be interesting cases of crosstalk and/or coregulation …

The Taxonomic Status And Geographic Distribution Of The European Hare (Lepus Europaeus Pallas, 1778) In Turkey (Mammalia: Lagomorpha), Yasi̇n Demi̇rbaş, İrfan Albayrak
Turkish Journal of Zoology
This study was based on 125 specimens of hares collected from 61 different localities in Turkey between 2006 and 2010. We present diagnostic characters, pelage coloration, external, cranial and phallic measurements, skull and phallus features, hair structure, and collection localities of hares from Turkey. Additionally, we analyze morphometric variations of 5 regional populations according to the physiography/orography of the study area. Among the morphometric variables, 10 characters (weight, tail length, basal length, condylobasal length, rostral breadth, height of braincase, foramen incisiva length, occipitonasal length, profile length, and mandible length) are found to be significantly different between the populations (ANOVA, P < 0.01). Principal component analysis of 22 morphometric measurements is performed, and 71.56% of total variance is explained through 5 principle components. The Thracian specimen is distinguished from other populations on the first 2 canonical discriminant functions and the cluster dendrogram. The hair structure, as examined by scanning electron microscope, is found to be flattened and imbricate. Our Anatolian specimens are discussed at the subspecies level, comparing them to the relevant literature, and it is concluded that Lepus europaeus in Anatolia is represented by only one subspecies, Lepus europaeus syriacus.

In this study, the seasonal distribution of mesozooplankton was investigated between 1999 and 2006 at a station located in the southeastern Black Sea region. A total of 40 cruises were done within the southeastern continental shelf throughout this period in order to collect mesozooplankton samples. A total of 10 mesozooplankton species were identified. The average annual highest abundances of species were 67,770 ind./m^2 in 2000 (Penilia avirostris), 50,048 ind./m^2 in 2001 (Sagitta setosa), 42,143 ind./m^2 in 2006 (Oikopleura dioica), 27,987 ind./m^2 in 2005 (Acartia clausi), 25,792 ind./m^2 in 2001 (Oithona similis), 24,806 ind./m^2 in 2005 (Pseudocalanus elongatus), 12,094 ind./m^2 in …
